AC3, Inverter FW D0.535-A0.535 - Battery FW 3013
I know I've got a problem with over voltage, that is being looked into by SSEN but I do wonder whether the AC3 is not helping?
My batteries, 5.2 + 9.5, are currently sitting at 52% with no charge restriction so in theory they could be drawing up to 3kw. However, when an over voltage error occurs the AC3 goes into idle and the inverter exports everything unless it drops out as well and/or the grid voltage comes down enough to keep the AC3 happy. It appears to take quite a while to wake up at times but the first action appears ( I could be wrong of course) to be an attempt to export, and that on occasion can tip the over voltage again.
I would have thought that the first action should be a 'charge battery', if there was capacity, to present the load to the inverter and help reduce any over voltage problem rather than presenting an export which would (?) cause the AC3 to increase voltage and possibly cause a problem?
I'm pleased to say that since starting to document this the grid voltage has gone down a bit in general so the batteries are charging!!
