After 3 other turbines I have this installed for 3 months now. I am really liking it. Have seen 2.2kw out of it. Check it out here :

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.
