[NSW] Neovolt 10.1kWh Home Battery (inc Inverter) Installed from $7,500, Redeem $1,600 VoltX Cashback (Limit 300 Claims) @ VoltX

760

Great price on a 10KwH AC coupled home battery system which includes installation. The battery also includes a 5kw inverter.

Australian guy from SA posted his experiences over six months on reddit. He worked out the ROI was 6 years without even installing solar, as he just charged up his home battery on off peak power at 8c/kw during midday. Then used the battery to draw power for the evening and night. Rinse repeat.

His posts are here https://www.reddit.com/r/AusFinance/s/606GQLsOKZ

Great info and commentary in his posts.

Had initially been waiting for powerwall 3 but this could be too good to pass up.

    • Waiting until November 1st for the government rebate is an option, but there’s a risk of installation backlogs due to high demand. Typically, installation costs may rise due to peak demand. We’ve seen this happen in other states where the uptake of batteries was significant, even when prices were higher. We expect NSW uptake to skyrocket, potentially causing a backlog into 2025. In fact, we were interviewed by Channel 7 News discussing the strong reasons you should not wait. This should be airing this weekend.

      Most definitely, you should weigh all options. However, one other factor to consider is the potential savings you can make from now until a future installation date.

    • Got a link to the rebate details?

      • Nsw battery rebate

        I guess there will be more info after the 1st of Nov. You can register to be informed.

        I just received letter on my mail that offer $2999 for the battery bundle including installation from one of the company, but the offer is only valid to end of this month.

        I will still give it a hard pass and will wait until the rebate comes in. I dont mind to wait a bit longer as i think the battery market are not mature yet at this point.

        • I did call this company. Turns out, $2999 is the price just from a 5kwh battery! To get the full system which includes a 10kwh battery plus 5kw inverter, the total is around $10000 at the end T_T

          • @oranged: Ah cool thanks for letting me know. It did sound too good to be true.

  • We already got a inverter with our solar. Whats the use of another inverter?

    • Your current inverter may not be able to work with a battery, not all can.

      • Does this mean our inverter needs to be replaced with this inverter? Or both in place?

        • How would they know what inverter you have?

        • Your existing inverter doesn't need to be replaced. The NeoVolt battery systems inverter will work alongside your current solar inverter. This set up will ensure compatibility with the battery, even if your current inverter isn't compatible with battery storage.

          • @VoltX Energy: if we have a 2.5KW system already can this be added to the current set up?

            • +2

              @May4th: If you mean a 2.5kW inverter, the NeoVolt battery can be added to your setup seemlessly.

              However, if you have a 2.5kWh battery system, this battery will likely not work properly on the same phase with a different battery system.

              On a separate note, if you have a 2.5kW solar system, it may not be big enough to fully charge the battery, but you can use off-peak rates to charge it.

              Our technical team can provide more specific guidance based on your exact setup.

  • Unfortunately in my area if you install a battery they immediately switch you to tou tariffs, and well the current rates are terrible. Even charging a battery off-peak the math is better staying on the current single rate plan.
    If Ithe battery was bigger or install a few then amber may make sense. But really not worth the cost of money.

  • +1

    What's the actual usable capacity in reality? The spec says 9.6kwh but some people say it needs to be at least 20% / 12.5% / 10% reserved for inverter or other electronics.

    10.1kwh battery capacity -> 9.6kwh usable capacity -> what's the actual usable in reality? 7.68 - 8.64 kwh?

    • +1

      The NeoVolt battery has a capacity of 10.1kWh with 95% usable, which gives you 9.6kWh usable capacity.

      You can adjust the minimum cut-off state of charge (SOC) via the smartphone app, with settings ranging from 5% to 10%. The default is set at 10%. So, the actual usable capacity can be up to 9.6kWh, depending on your settings.

      • Hi rep.
        * Can this system installed still charge the battery from solar when disconnected (running in backup power mode) from the grid in the instance of a blackout?
        * What is the app that is used to control the system called ( most battery rely on good software interface these days)
        * And is this the cost for the first battery, what's the cost for an additional bare battery (as won't need another coupled inverter)
        Cheers

        • +1

          Can this system still charge the battery from solar when disconnected (running in backup power mode) from the grid in the instance of a blackout?

          Yes, this scenario is possible. With AC coupling (integrating with existing set up), the solar can’t charge the battery during blackouts. However, with DC coupling, where your solar is connected directly to the battery through our hybrid inverter, the solar can still charge the battery when the grid is down.

          What is the app that is used to control the system called (most batteries rely on a good software interface these days)?

          The system is controlled using the Neovolt app, just search Neovolt on iOS or Android app stores. The app is really clean and very functional. It's designed specifically for this inverter and battery.

          And is this the cost for the first battery? What’s the cost for an additional bare battery (as it won’t need another coupled inverter)?

          Yes, the cost of the first battery and inverter package is $7500, and with $1600 cashback this comes down to $5900. An additional battery by itself is priced at $6,000. Our cashback can only be applied once, per installation address.

          • @VoltX Energy: Awesome thanks rep 😁

          • @VoltX Energy: Hi Rep
            The 5kW inverter that comes inbuilt with the battery - is the hybrid type you mentioned for DC coupling of the battery (so that Solar can charge batteries even in grid outage and supply the house?)

            If it is a regular 5kW battery inverter that comes with battery, can it be swapped with 5kW/10kW hybrid version for hooking up the solar to use the above grid independent solar charging of battery and possible house supply when grid is down?

            How much extra it would cost us to use a 5kW/10kW hybrid inverter to bw swapped in place of regular 5kW battery inverter that comes in?

            Can this product supply the whole house in an event of grid outage? (say like Tesla PW2 & the likes?)

            How much is the continuous battery supply capacity DURING a grid outage? - Is it 5kW or less like 4.2kW?
            What is the LRA value, limited short time surge kW capacity and for how many seconds it is?

            • @maddykartik:

              • Upgrading to a 5kW hybrid inverter costs an additional $300. Currently, there’s no 10kW hybrid inverter option available.
              • The product is typically set up to back up 1 light circuit and 1 power circuit. Additional circuits can be backed up for an extra charge. For full house backup similar to Tesla Powerwall 2, a larger inverter would be recommended.

              Regarding LRA values:
              * The continuous supply capacity during a grid outage is 5kW.
              * The surge power capacity is 10kW for at least 5 seconds.

              Hope these help!

  • Can you stack or chain two of these together for higher capacity?

    • Yes, you can add up to 5 more battery units, giving you a total of 6 NeoVolt 10.1kWh Home Batteries with a combined capacity of 60.6kWh.

  • how programmable is this battery- I am on the ovo ev plan, and would like to take advantage of the cheaper electricity. could I charge the battery from the grid between midnight and 6am, and then run the house with it in the morning, and then charge it to full again b/w 1100-1400, and then run the house with it in the evening?

    and can it provide backup in a blackout? I have a 3-phase house.

    • Yes, through the app, you can set specific times for the battery to charge from the grid and to what percentage, as well as set it to discharge at certain hours.

      Yes, it can also provide backup during a blackout; this feature is optional and involves some additional electrical wiring and work. We can install it in a three-phase house by adding a smart meter. This scenario is very common.

      • how fast does it cut in during a blackout?

        • This battery system is designed to cut in almost instantly during a blackout, typically within 10 milliseconds, ensuring minimal disruption to your power supply.

      • Hi, I have a few questions:

        1. Does the app communicate directly with the battery (e.g. you connect the battery via wifi/bt, and then the app communicates via wifi/bt to the battery) or does Neovolt host a web service that battery sends out telemetry to their web service and back to the app?

        2. Will this work ok with a solar set up that uses Enphase microinverters?

        3. What kind of discount would you provide for multiple batteries?

        4. Can these be installed on an outdoor wall, or should they be installed inside?

        • +1
          1. The NeoVolt app communicates with the battery via a web service. The battery sends telemetry to the NeoVolt web service, and the app retrieves this data for user interaction. So to clarify, the system can be accessed remotely, via the app.
          2. Yes, the NeoVolt battery system will work with a solar setup that uses Enphase microinverters.
          3. For discounts on multiple batteries, please contact our sales team directly for a personalised quote based on your needs.
          4. The batteries can be installed on an outdoor wall or inside, but we recommend an installation location that provides some protection from extreme weather conditions to ensure optimal performance and longevity. The system is IP65.
          • @VoltX Energy: Thanks for the detailed response. I'll get in touch with your team about #3.

      • so I can set it to charge up from the grid while I export my solar at the same time?

        what is the smart meter needed for backup? I have a smart meter for electricity all ready- is it another seperate meter?

        does it connect via 4g/wifi/ethernet?

        • No, you can't set it to charge from the grid while exporting solar simultaneously. Any excess solar energy will automatically go to the battery first, and only once the battery is fully charged will the solar export to the grid.

          For backup functionality, a separate smart meter specific to the battery system is required, even if you already have a smart meter for electricity.

          The system connects to you home WiFi which can then be accessed from any location using the mobile app.

          • @VoltX Energy: how quickly can the battery charge from empty to full from the grid on 3-phase please?

            if my all my solar generation is being consumed all by my house, can the battery be force charged from the grid at certain times (eg 1100-1400) simultaneously?

            I wish there was a simulator/demo for the app somewhere

            • +1

              @derdew: The app is sort of a rebadge of the AlphaESS app with cut down features. The AlphaESS app has a demo if you want to get a feel of what might be available.
              But yes, the batteries can be force charged from the grid. The app allows you to configure at most 2 charging periods and you can set up to what % you allow the batteries to be charged up to.

              Regardless of phase, I believe the you'll be limited by the max 5kW limit of the inverter. So around 2 hours to charge 1x battery.

            • +1

              @derdew: A 10kWh NeoVolt battery can charge from empty to full in about 2 hours using a 5kW 3-phase grid connection, though it might take slightly longer due to inefficiencies.

              Through the NeoVolt app, you can configure the system to charge from the grid at specific times, such as 11:00-14:00, even if your solar generation is being consumed by the house.

              For a desktop demo of the app, you can visit the Byte Watt website and log in as a guest:
              https://monitor.byte-watt.com/login

              Or contact our support to schedule an appointment to visit our Regents Park office for a demonstration of the mobile app 🙂

      • I am also on ovo plan.

        Can I charge the battery during the free electricity period? (11am - 2pm)? How long does it take to charge?

        • Yes, you can set 11a-2pm to charge batteries from grid. Since the inverter takes 5kW max, you're looking at pulling 15kWh in 3 hours. If you get 1 battery, you can fully charge it in 2ish hours then it stops pulling fro grid. If you get 2xbatt, 3 hours is about 75% worth.

          • @mbcd: Yes, totally correct. This scenario might be worthy of adding a second inverter, rather than just a battery. Both ways work, but depending on the solar setup (if there is one) and your consumption, you might be able to fully charge and discharge both batteries twice per day.

    • That plan is for EV charging at night, not battery charging, just sayin'

      • The OVO EV plan is for all consumptions during 12AM-6AM unless you gave them control on your EV so they know how much is for charging.

      • Charging an EV is just charging a battery after all.

        • Yes. All I’m saying is they can’t differentiate between charging EV and normal household consumption as long as you don’t give them access to your EV. Same goes for AGL EV plan.

  • Hi Mate,
    Just wondering if you install in regional areas/Central West NSW - Bathurst/Orange/Dubbo. If so is there an additional install charge?

    • Yes, we do install in regional areas, including Central West NSW (Bathurst, Orange, Dubbo). There is $500 a travel fee as our trusted install team based in Sydney will travel to your location for the installation. If you have any more questions or need further details, feel free to ask!

      • Is the $500 applicable for Queanbeyan/Googong too?

        • Yes, the $500 is applicable for Queanbeyan/Googong too.

    I will not trust unknown brand of a battery no matter how cheap the price is.
    Lithium battery is very easy to catch fire and for a small overseas manufacturer, the battery quality has not been tested from Australian market and the manufacturer’s financial stability is unknow.
    I would rather pay my bucks on a battery from a larger enterprise.

    • Thanks Finn

    • Irony that most dangerous home batteries have been lg, 13 fires.
      Imagine spending a extra 2k over growatt, just got your house to burn down.

    • There are types of Lithium batteries. The ones that have been known to catch thermal runaway aka fire are NMC types which I believe are used by the LG Resu. I haven't checked if an LFP battery was part of the recall.
      The relatively safer type is the LFP battery.

      The Neovolt battery is listed in https://www.cleanenergycouncil.org.au/industry/products/batt…
      which according to sites says
      "the products included on the list have been independently tested to confirm that they meet the necessary electrical safety and quality standards under the Clean Energy Council’s Battery Assurance Program."

      How extensive those tests are I have no idea since the ones recalled from trusted brands such as LG, Red Earth, Redback, Varta have been in the approved list.

      • The NeoVolt batteries are LFP and not the Lithium Ion batteries that caused major issues over the past few years. You’re in much safer hands!

  • Hi Rep, appreciate you joining to answer questions.

    Is this an actual VoltX product? Is the Adelaide guy a reseller of yours or a competitor?

    What’s the ideal setup for three phase with two solar systems? Assuming one battery or two batteries.

    • Hi there, no worries! Happy to join and help with your questions.

      The NeoVolt battery is a co-branded product with VoltX. The guy in Adelaide is a business partner, although we are different entities, I wouldn't suggest they are a competitor.

      We’d be excited to review your specific scenario with a three-phase setup and two solar systems and provide you with the best solution. Both one and two battery systems can work and you might have the option of adding multiple inverters. Our solutions architects will give the best options. Please reach out to our team for a detailed consultation. This is done at no cost and you and with no obligation.

  • Hey VoltX Energy, does the inverter or battery have a generator input so I can feed power in from my V2L ev?

    • Yes, the inverter and battery do have a generator input. Please contact our team to discuss the details and how it can be integrated into your setup.

  • @VoltX Energy Are there any plans to come out with true 3 phase batteries? That can power all phases if the grid is down and not just one?

    • Our single-phase system is tried and tested and works very well with 3-phase systems. However, we are having discussions and testing for a true three-phase battery. It might be 3-6 months before we have a clear answer on this.

    Hi Rep
    The 5kW inverter that comes inbuilt with the battery - is the hybrid type you mentioned for DC coupling of the battery (so that Solar can charge batteries even in grid outage and supply the house?)

    If it is a regular 5kW battery inverter that comes with battery, can it be swapped with 5kW/10kW hybrid version for hooking up the solar to use the above grid independent solar charging of battery and possible house supply when grid is down?

    How much extra it would cost us to use a 5kW/10kW hybrid inverter to bw swapped in place of regular 5kW battery inverter that comes in?

    Can this product supply the whole house in an event of grid outage? (say like Tesla PW2 & the likes?)

    How much is the continuous battery supply capacity DURING a grid outage? - Is it 5kW or less like 4.2kW?
    What is the LRA value, limited short time surge kW capacity and for how many seconds it is?

    • I would love to know also 😎
      I also found this site which has more detail and specs(link via the app for the control of battery) https://www.byte-watt.com/

      • Upgrading to a 5kW hybrid inverter costs an additional $300. Currently, there’s no 10kW hybrid inverter option available.
      • The product is typically set up to back up 1 light circuit and 1 power circuit. Additional circuits can be backed up for an extra charge. For full house backup similar to Tesla Powerwall 2, a larger inverter would be recommended.

      Regarding LRA values:
      * The continuous supply capacity during a grid outage is 5kW.
      * The surge power capacity is 10kW for at least 5 seconds.

      Hope these help!

      • Thanks @VoltX Energy

        Just wondering when Tesla PW2 is rated for the same 5kW battery inverter output and still manages to backup whole house, why cant we do the same thing here?
        (of course we exclude power hungry things like aircons, ovens, elec hot water system, pool heater pump etc)

        5kW is plenty for all other house load.

        Would you be able to do full house backup at least when running 2 of your units in parallel - which gives a full 10kW backup output on 20kW battery pack?

        • Yes, what you suggest is definitely possible with a small electrician’s fee. We typically avoid backing up the entire house because the likelihood of tripping the fuse is high if multiple appliances run simultaneously. However, with user awareness and managing the load, this can be effectively avoided. Running two of our units in parallel would indeed provide a full 10kW backup output on a 20kW battery pack, allowing for a more comprehensive backup solution. We are flexible and can customise the setup based on your needs.

          • @VoltX Energy: @VoltX Energy
            Could you please be more specific on how much is the "small electrician's fee" for whole house backup on 5kW inverter output? (to exclude power hungry things like aircons, ovens, elec hot water system, pool heater pump etc)

            If all the pricing is right with above features, you would have people be seriously considering purchasing the product

            Just asking - even if the battery trips, it is all about switching off the power hungry appliances and resetting the battery tripper?

              @maddykartik:

              small electrician's fee

              In my experience a small electrician fee is at least $1000

              • @easternculture: We understand your concern about electrician fees. However, since our electricians are full-time in-house, we’re able to offer more competitive pricing.

            • @maddykartik: Certainly! Here are the pricing details for setting up a whole house backup:

              • $500 for manual backup, including 2 circuits.
              • $600 for automatic backup, including 2 circuits.
              • $100 for each additional circuit.

              That's correct, if the inverter trips, it’s simply a matter of switching off the power-hungry appliances and resetting the inverter.

                @VoltX Energy: Thats close to the mates rates my electrician offers and still makes a killing. Definetly not a small fee though .

              • @VoltX Energy: @VoltX Energy
                It still doesn't address my question.

                Please advice your electrician fees for backing up the entire (not just 2 circuits) house on 5kW Inverter output on 10.1kW battery system.
                (of course we exclude power hungry things like aircons, ovens, elec hot water system, pool heater pump etc)

                Can your product backup the entire house in the first place? (Tesla PW2 does it on the same 5kW inverter output though)
                It is more around if your product is safely capable of doing it and if there is in-house expertise to do it.

                Not sure how you calculate number of "circuits" - individual GPOs counted as one or the whole circuit from power board counted as one with multiple points under it.

                For eg:
                My house have one MCB for every room in the power board. There are like 7 MCBs (6A-10A) covering various rooms with lights and GPOs. Additionally AC, Oven, elec hot water are on extra separate MCBs with higher Amp (16A-20A) power rating.

                So to backup all those under light duty 7 MCBs (6A-10A), would it be like $1100 ? ($600 + 5*$100)
                Very costly though !!!

                If you are counting individual GPOs as one circuit - god forbid, it is going to cost more than the unit to backup :)

                • +1

                  @maddykartik:

                  • We suggest backing up 2 circuits and can extend to 4 if needed. For a reliable whole house backup that can properly support your whole house, a different set up may be needed. We would need to review your scenario in detail to provide options. Please contact our team for a thorough assessment.
                  • For a standard installation, we use a 6mm cable with a 32amp MCB for both grid and backup port. For whole house backup, we would need to upgrade to a 10mm cable with a 50amp MCB to prevent tripping during a blackout.
                  • The Tesla Powerwall 2 uses a gateway to control the backup, which usually costs an additional $1500.
                  • When we refer to circuits, we mean the entire circuit from the power board, not individual GPOs. For example, if your house has 7 MCBs (6A-10A) for various rooms and additional MCBs for high-power appliances, the cost to back up the 7 light-duty MCBs would be calculated as follows:
                  • $600 for the first 2 circuits.
                  • $500 for the additional 5 circuits ($100 per circuit).
                  • This totals $1100 for backing up all 7 light-duty circuits.
      • Hi @VoltX Energy
        In future if we decide to include a different battery unit say the likes of Tesla Power Wall 3, can it co-exist with your battery or should it be just one or the other?

        • It would be best to use one type of battery system at a time. Different battery units typically have varying management systems and integration requirements, which can lead to compatibility issues if combined

  • For systems that have AC coupled Solar arrays (Enphase Micro inverters), can this energise the micro inverters in event of a blackout, I haven't looked into this too much but I'm assuming it would need to be placed behind a switch so it doesn't feed back into the grid in event of a grid outage.

    • I have Enphase microinverters. They couldn't get this feature to work with AC coupled unfortunately. So, no, the sun is wasted while there is an outage.

  • man this is very tempting. any idea what the shipping costs are to WA?

    • We can quote a delivery cost to WA. Please contact our support and we can help out.

    • well thats a sobering read

    • not surprising that such aggressive testing just ruined most battery setups with severe loss of capacity. Show us the individual cell voltages as they approached their full discharge and full charge. With such aggressive charging and discharging this would have unbalanced the cells and most battery balance systems need days to rebalance a pack so that it can regain full capacity to allow the cell voltages to stay together at full discharge and discharge To get a 10 yr lifespan need to operate between 20% and 98% SOC. LiFePO4 are not set and forget and any system that does not allow individual cell voltage monitoring and management (balancing) is less likely to last the distance. The EV battery world has much better quality control than the residential storage battery world.

  • What if my solar inverter is already battery compatible, do I still need an additional inverter?

    • If your solar inverter is already compatible with a battery, you won’t need an additional inverter. However, it’s crucial to check for compatibility with your existing inverter. Compatibility includes matching voltage, communication protocols, and other technical specifications. Please contact our support team, we can review this in detail for you.

      • Would that reduce the price then?

        • +1

          Unfortunately, the price reduction applies only to the whole unit, not just the battery. The regular price for a battery and inverter unit is $7500, and an extra battery alone is $6000. Our current rebated price for the whole unit is $5900. You are much better off taking the whole unit, even if you store the inverter as a spare.

  • can you install multiple batteries on a single phase system?

    i.e. if i want 20kWh of storage can I install two of these?
    do they work well together?

    • +1

      You certainly can. You can add up to 5 more battery units, giving you a total of 6 NeoVolt 10.1kWh Home Batteries with a combined capacity of 60.6kWh.

  • Anyone get/got this system would love to know how they’ve gone?

  • What the product warranty and performance warranty are for this battery system?
