Hi All,
I'm using a SunGold SPH8048 which is a SNRE 8k hybrid inverter, 8kw of panels spread over the 2 MPPTs, and 400ah of SunGold 48v LFP batteries. My setup has been running for a few weeks now and I believe I have everything dialed in the way I want but there is 1 thing that seems off with charging the batteries. I'll try to describe below using a few scenarios.
1. During the day the solar charges the batteries fully and powers the house loads, then at night the batteries start to drain. In the morning when the sun comes out the batteries start to charge again. This is expected behavior and everything works.
2. During the day the solar charges the batteries fully then the house loads exceed solar production and the batteries start to discharge. This is also expected. HOWEVER, when the house loads drop back down, the batteries do NOT charge back up until the next morning. It's as if after the SOC reaches the fully charged limit it has to drop X% before the inverter will start charging again. I cant find any setting that would cause this. Is this built in to prevent short cycling of the batteries?
Thanks
