8kw split over 3 phases would probably explain why it was discontinued, 12 kw a much better option.

 

[jezzad]

Ive only ever seen the 12kw version.
Is it a price thing or any other specific reason why you don't want the 12kw instead of the 8kw?

House is 3 Phase we only need 5kw and 12kw is about R20k more than 8kw

Do you have any 3 phase equipment? Easiest is often to just put everything back on one phase. Then you can use a single phase inverter.

I agree with this. If it's not needed then just use 1 phase.

Anyone know where I can get a 8kw 3 phase Sunsynk Inverter? Looking online seems only one shop - https://volocityenergy.com/products...JnPaQxjgGEowgeCCb7O5b3ij9g7HSMat5TVhh3OGWhNU0

Happy to buy direct from installer as well.

Haven't seen...but for a few grand more you can get a 12kw Deye

I'm gonna be spamming a few threads with the monthly production Google Form. There are a lot of new installations, the more data we gather the better. Just for interestest sake.

Please complete the form with your monthly production stats. Stats can be seen here in the 1st post.

I have a DEYE 8kVA single phase inverter with 2x Pylontech UP5000 batteries, no solar panels yet.

Is there a way to tell the inverter to only charge the batteries to say 80% SoC in order to save a little on the cycles?

The lowest SoC that I have seen during a 4-hour loadshedding stint was 54%, so I think I am safe starting at 80%.

Any merit in this approach?

You set the SoC in the system work mode.

By using the time of use table?

Yes

450kwh of lithium batteries or AGM/GEL?

That is an INSANE amount of storage

I think there is a mistake there. Unless it's for 2 to 3 weeks of storage.

Correction 14.3 + 7.4 kWH
All Lithium setup

Lol. There's a pretty hefty difference between 450kWh and 21.7kWh

I mixed up my Ah and Kwh :'(

21.7 @ 54v = 401.85Ah

Good thinking. The problem is that one can only control the charge from Grid and Genny, not solar.

JP van Riel did request it on the Sunsynk forum more than 2 years ago, but like much of the requests there, it was ignored.

Whoops. Had my math malfunctioning a bit...

Batteries should be 48V nominal, so 452Ah.
