First of all, did anyone know where I can get the actual manual for this battery? I have 2 4.8kw shoto batteries (although 1 currently went in as it wasn't charging for some reason) Ohm inverter I have always had it set on % mode, and I never realized it was a bit of a guessing game until recently. Although it always seemed fairly accurate. In any case, installer has insisted to use V mode. But this is confusing me. Currently have it set to shut down at 47V, restart at 48v But I really want to use the battery as close to full capacity as is, safe. The idea is to try to get us through the night after sun set (which should theoretically work with around 9. 6kw of available backup stored?) 80% of that is 7.6kw Sundown between 5 and 6, and thereafter we may draw 400-600w till 9.30 and from then on 200-400w Any ideas?
