Hello - first post !
my system just won’t use the battery - it only runs when solar is working and completely shuts off when the sun goes down - starts back up when I run the generator at night but “ ignores “ the battery It charges the battery no problems.
I am completely off grid ( wind / solar ). I am using a Growatt SPF 3000TL HVM-24v. I have 12 x 2.2v lead carbon batteries.
I suspect it’s a setting issue that I can’t figure out - how do I get it to use the battery after dark instead of trying to access a non existent grid ?
can anyone suggest settings for a setup with no grid input at all…..
I did get a fault 19 once …. Relay issue ? Could this be a defect where the inverter is not switching to battery as a relay is not working ?
All help most appreciated.
