    Max of 10kw back into the grid in qld & what's the idea with a 15kw inverter with 20kw panels .

    • +5

      Hi Spock.
      It's a max of 10kw inverter per phase, with a 5kw export limit. 95% of homes in Brisbane have a single phase connection, hence the 10kw inverter limit, with a 5kw export, but 133% panels for the rebate on the 10kw inverter.

    • It's not for everyone (wasn't for me) but if you're a high consumer it's worth it. My friend has 20kw of batteries, pool heater, two EVs, a few fridges/bar fridge and central a/c. They have a 20kw inverter system and generally don't hit their export limit as they self consume so much of their solar generation. I'm pretty sure they said they have an export limit of 15kw.

    • +4

      It is only logical to over provision the panels to maximise photons for optimum solar production. 🖖

    • +7

      Thst would be the Feed-in saving component, not the whole picture, as your bill doesn't show what you saved and what actually didn't have to buy, as the power is sourced from your roof first.

      For example, I estimated this system to save someone around $1600 for the year just in solar export alone.

      System Inverter size (20) x 4.4 hours of sunshine = 88 kw hrs made per day, on average (32,120 kW hrs made per annum)

      32,120 x 0.5c (F.I.T)

      = $1606

      Now Imagine if this person cranked AC all day, had a pool, or an EV, the savings can be quite high.

      Yes pigeons can be very bad, and nest in and around the solar panels. Ther are 3rd party solar cleaners that are doing 'bird proofing' as a serivce.

      • +2

        I’ve got a 10.36/8kw inverter, had since 2021, yes FIT was higher but I’ve saved $4600odd on my consumed power throughout the day and fed in $3200 worth.
        So the system has already paid itself off

      • +2

        The calculation is off. You mentioned it is a 15kw inverter, so it is really 15 x 4.4hrs (although this is very optimistic) assuming you have an all your panels facing north on a good angle. You then have a 5kw of solar export limitation, so in theory you can’t sell all your FIT to get that $$ saving figure.

        Another confusion with this deal is that you are providing a three phase 15kw inverter but on your condition below this must be a single phase property as the condition?

        • The calculation is of because I think there is a typo in the post. It's a 3 phase system, so can export 15kw. The terms and conditions state that you must have single phase - I'm thinking it should be three phase.

          It's confusing everyone.

        • I thought I was being conservative. I added conservative numbers to this calculator.

      I don't think you understand how solar works…

  • +1

    If I have an old (>15 years old) existing 5kw system already, what's the general protocol when getting an upgraded system? Do they normally get rid of the existing panels and old inverter or just add to it?

    • +1

      depending on roof space, installation, and existing warrany on the existing setup, the rebate usually makes it a wiser choice to take down and start again, however you can add another system next to it.

      • Is it possible to move the old panels and system to another house and is it worth it cost wise? I wouldn't mind replacing our 5kw system and getting it installed on my parents house.

        • +1

          not at all.

  • +1

    45 is a crapload of panels on a roof! I doubt that many would fit on houses in my area..

    • +2

      It's definitely a big system for big power uses, or someone who plans to use a heap in the future.

  • Any deals going on smaller residential systems currently? We've been in a new house for a few months wirh an existing system but its pretty dated.

  • +2

    I have a massive house with 11kw (25 panels). How the heck would anyone fit 45 on their roof? You'd have to cover the entire roof (that faces away from the sun).

    Unless you've got a packed house, a massive battery, and an EV this would be overkill, surely.

    • +1

      Heaps of big houses that need this power can easily. Your house may even be 2 storey, and can fit 11kw on?

    • I have a massive house with 11kw (25 panels).

      We have 32 panels and room for at least another 20… Only 4brms.

      This would be handy for aircon & pool heater (we ran it during the hols cost $12-$15/day in excess power drawn from the grid).

      • -1

        Do you have a flat roof? If you put panels on the direction not facing the sun, you'll get like 30% less out of them.

    • +1

      I've got 32 panels, 16 facing north, 9 east and 9 west. Works great as I'm on a time of use tarrif where electricity is more expensive before 9am and after 4pm. The direct east and west panels help heaps. I came from an older system that was only facing north and it wasn't producing much when electricity was most expensive. I've easily got enough space on the east and west facing roof for additional 9 panels each (would exceed the 45 mentioned).

      In saying that, I've got a pool and my wife and I run family business from home and our 10kw system exceeds what we need, a 20kw system would be overkill for most people.

      • Yeah …disagree … wish i got a bigger system … rather have peak output for x2 EVs which only get charged when not at work - ie perhaps 2.5 days / week of sunshine including weekend and also bit more allowance for degredation.

        Additionally with vehicle to home just around the corner … more incentive to keep car charged. I'd fit as much as my roof could handle.

        • Yeh true. I guess if you can soak it up with the EVs.

          We only have single phase so we couldn't go larger than 10kw, we had a quote of $6k to upgrade the meter to 3 phases to allow us to the purchase a larger system, but would be difficult to get a return on that added expense.

          Just like today as a example. We generated 69kWh, of that we exported 51kwh. So still had plenty of spare power there.

          Our average monthly bill is around $50, which came down from around $230 a month. Chasing diminishing returns looking at batteries / oversized systems.

      • Nahh. The biggest you can go is the best investment. Who knows when you get a home battery and BEV/PHEV car one day.

  • Just started building. Should we start discussion now? Or wait til it's almost ready? 3 phase with pool

    • Good morning Brandon,

      If it's 2 storey, it might pay to talk to the solar installer now.

      • Sure mate. What's your best contact?

        • Hi, you can call anytime 0411 348 400

  • Do you have a packaged deal for adding a battery with this solar offer?

    • not just like a blanket battery deal, but if you'd like to explore battery options, just give us a call and we can go through some options

    • +1

      yeah mate, forever providing a bit of a laugh and entertainment. I can't help myself as solar is just so boring, bland, and full of sharks and cowboys.
      That first video was actually my parents house during the big bad bushfires filmed during the 2019-2020 NSW fire. The red light was on because there was no power in the grid, the sky was yellow-orange because of the nasty fire… I saw the red light blinking so I pumped out a video. Love Growatt, and that same inverter is still going, since 2017.

      the 2nd video is my Fronius inverter, 8.2 Primo, the noisy dog.

      the third, well didn't TacoBell turn out to be a let down over here?!

      • I've been subscribed for a little while now.

        Love it. Keep it up.

        • +1

          Thanks. Sure beats the same monotonous tone and content driven by this industry's masses. Not too many true and honest in this industry, The circle jerk of the never-ending Virtue Signalling gets a bit tiring.

  • The link on the home page ‘free quote’ is broken, leads to an error page stating ‘this page doesn’t seem to exist’.

  • Very interested in this deal but according to the expire date I may be too late.
    Currently have single phase but looking to upgrade to 3 phase shortly as we have quite a lot of roof space (Not sure if it will be enough for the amount of panels stated though!)
    Do you service to South Toowoomba (4350)?
    Have previously used Solarhart on our old house but won't be using them again
    Thanks!!

    Edit: is it possible to install such a large system before moving to 3 phase power?

    • no, as we need to connect it.

      How much is the three phase connection? $5000 all up?

      Yes, we can do in Toowoomba.

      • Thanks for the reply, I’ve spoken to my electrician and we will be going 3 phase asap (we need it for our new oven). Just hoping Ergon won’t stuff around with their side

        Will contact you as soon as we get it swapped and hopefully the deal hasn’t changed too much!

        Thanks

        • no worries
