Hello everyone,
I am working on a battery, that should cover our nightly energy consumption. We have ~6.5kwp of photovoltaic panels. They produce about double the electricity that we need and I would like to charge my battery at daytime and drain it at nighttime.
Therefore I would need a way to control the current that goes into the grid at night. Idealy I would like to use an inverter, that just sends as much power into the grid, as our house needs. I think our solar inverter is not ideal for use with a 14s battery (which I plan to build) and also is not controllable (it just pumps the whole power from the solar panelsinto the grid).
I would be glad to get some inputs aboutpossible inverter setups. The inverter should be compatible with 3 phases (ideally individually cover the phases) and 230v/50hz and should deliver a minimum of ~2kwp (I think it would be ok to get higher peaks from the grid at the moment... I rather would like to cover the permanent load).
Thank you for your inputs in advance!
Cheers

PS: right now I have ~800 18650cells lying around and growing, ~200 are tested and are <80m? >1700mAh... perhaps I'll even drop out the cellsbelow 1900mAh... suggestions?
