Hi. I have a Multiplus II, Gerbo GX and MPPT 150/85, 12 Panels and 2x Averge 4.8kwh batteries. The batteries are managed by their internal BMS software. When the batteries are completely drained ( and there is no grid input), the system goes into acontinous reboot cycle, untill the PV output maches the current power consumption. Is there a way to "tell" the system, not to output power, untill the batteries reach a certain %, lets say 20%. Do I need to get additional hardware? The company who installed the system, cannot iffer a solution for this challenge.
