  1. Richard Ashley started following BMS to inverter issue

  2. BMS to inverter issue

    Richard Ashley posted a topic in Batteries
    I have two Volta 10kWh batteries connected to a Deye 12kW inverter. One of the batteries is showing only 2 green lights of charge, the other 4 green lights. The inverter states 80% SOC . I tried switching off the fully charged battery and had an inverter error saying battery over charge on the 2 bar battery. I checked the logger and there was no BMS data except for 100% SOC. It would appear the second battery is not communicating with the inverter. Is this an installation mistake, or is it normal for one battery to dominate?

  3. Strange load reading on one phase

    Richard Ashley posted a topic in Inverters
    I have a 12kW 3 phase inverter with 4kW solar and 20kW batteries. When I put a big load on phase 3 the voltage rises and the grid shows negative load (CT load is normal). Phase 1 behaviour is normal. I get a similar issue on phase 2 as well. What would cause this?
