    MPPSOLAR PIP5048MG 5kW with 2x2kWh Chevy Volt battery Error 58 (Inverter Voltage Too Low)

    My inverter is working great without the batteries, but if I connect my battery array I get Error 58 (Inverter Voltage Too Low). I average around 4kWh on my output. I wonder if there is a setting to load balance with grid or solar so the battery doesn't run out of power. Do I need more batteries...
