Hello,
Looking installing battery to my solar system, i initially was looking at Tesla Powerwall but due to being on 3 phase power Tesla did not look like a good option. My current inverter is a non hybrid sungrow so would have to replace it to a hybrid one but i have been stared toward Sungrow batteries so i can just add capacity when need seems great but keen to know anyone else with a the full sungrow setup how do you find it?
100% i should have gone a hybrid inverter.
Why?
Cant you get it AC Coupled ?
Sungrow Batteries Vs Tesla
lithium iron phosphate (LFP) vs nickel-cobalt-aluminum (NCA)
IMO LFP is the better choice for a residential battery.
I am using 3 x ZBM3 flow batteries for 3 phase power ;)
Also make sure your inverter is V2G compatible, if only using one battery it can be useful for the 3am - 7am dead battery zone :/
Keen to know whats the setup ? What sort of inverter you are using ? and your usage usecase
Some experimental stuff I probably shouldn't divulge :P
We have a full sungrow setup (3 phase). It has been mostly stress free besides a few technical glitches with their iSolarcloud platform; as in not being able to log in or it reporting nothing on the graphs. Seems to be all resolved now
We also have a full Sungrow stack of batteries (25.6kW - 3 phase) - no real issues or anything and it's integrated into my HomeAssistant setup.
Interested to know how much this setup cost. I have a three phase solar setup with a hybrid inverter and am looking to have batteries added to mix
Our install cost $20k for 10kW Hybrid Inverter (SH-10RT) with 8 batteries (22.4kW total) including install and removal of two old inverters. It would definitely have been better to have had a Hybrid Inverter installed in the first place, but hindsight is always 20/20 - our previous solar installation had already paid itself off.
I later purchased a single battery (3.2kW) to add onto the stack of 8 to max it out for $1.6k
Total cost would be $21.6k - this was unfortunately before the rebates.
It's expensive, but the math checked out where at the current average electricity prices it would take 10 years to pay off (roughly equivalent to the warranty in terms of warranted use capacity).
The storms in December took out the grid a few times (luckily for our area it didn't last long) - but we were 100% uninterrupted during the whole ordeal. Would not have known the power was out if the app didn't send me a notification or friends telling me they lost power.
Another coworker who had a stack of BYD batteries installed wasn't so lucky and had no grid power for days (to the storms) - but his batteries recharged enough from solar during the day to power his house and charge up for the night's use while the grid was out so it worked out great for him too
We did switch over to Amber Electric and have managed to sell some power during price spikes on the whole sale market - hopefully this would speed up ROI
6 months in now and we haven't paid a cent for electricity, and account is currently $520 in credit.
Where abouts are you located? If in Vic would be interested to know your installer
i got quoted 15750k for 12.8kw sungrow and SH-10RT, who was your installer?
@SpeedAU: Our install was done by Arise Solar - I personally can't recommend them (even though I have had no issues with them) as they are apparently known for bad after-sales support if you run into issues - which is likely why they're "affordable". It's also a thing where "people only usually make noise if there's something wrong, and you'll never hear from the people who have no issues" kinda thing.
We had our initial panel and inverters done by them as well in 2020 and didn't have any issues which is why we went with them again for battery install. I've also had them do standard panel and inverter install for my dad's place and no dramas there either.
I've seen many stories about people having inverter issues down the line and it takes forever to chase for a warranty claim/someone to come out to look at it - this is because they just subcontract out the job for much lower to other contractors have them do the installation while they provide the stock themselves.
I've been to their warehouse in Acacia Ridge/Coopers Plains (in 2020) to have a chat with them during the inital quotation and what not - so they are definitely local despite all the phone staff being seemingly from overseas call centres (as per some of the negative reviews found too).
Sungrow are known for very decent Australian support and I've been on the phone with them about some questions and integrations around the battery and inverter and they've definitely supported me well.
SolarQuotes website is a great resource if you are looking for an installer to pick from
+1 Interested
Also did you think now having hybrid would've served you better ?
