AC coupled inverter battery PV set up
Hello all, I'm sure this has been asked before but I can't find it so sorry if I've missed the answer somewhere.
I have three single phase SunSynk inverters a 3.6kW , 5.5kW and an 8kW.
These inverters are AC coupled and grid tied no other coms cables etc. The 8kW is in a separate building some 30m away from the other two but all connect to the same consumer unit and grid connection point. The CT's for all three inverters are in the same place at the grid connection point. I know I can't parallel them due to being different inverters and the distance between and I don't need to parallel or load share etc.
My question
At present I have a set of SunSynk batteries on the 8kW , I know I could increase the capacity of these but I need a charge /discharge rate of more than 8kW.
So can I add another set of batteries to the 5.5kW ?
Thanks for this Groots. Even though it's been weeks waiting for an answer from Sunsynk via their ticket system I have actually spoken to a SunSynk engineer this morning. Thay have confirmed what you've said in that I can put batteries on more than one inverter and they confirmed there are compatibility issues with different batteries. However there are two types of battery that can be used together on the same inverter and that is SUN BAT 5.32 and the SUN BAT 5.12 these appear to be the two types I have. The SunSynk Eng is coming out tomorrow so I'll let you know how it gets on. However I want them moving to where they should be anyway so not really fussed if the manage to get them working on the 8Kw or not.
