Setup the Inverter for Voltage control or open loop with the batteries
Voltage control or
Open Loop values for
Absorption and Float
Voltage should be
54.40V
Absorption time and
interval are set at 0.25
Hrs and 45 days
Charge current is
dependent on type
and number of
batteries and Inverter
Quatro 48/3000 – 35A
Quatro 48/5000 – 70A
eFlex < 55A
eVault < 150A
Pro tip: If a BMS error occurs when powering up the inverter, turn the batteries off. Connect the inverter and any
battery breakers so that power can flow from the batteries to the inverter. Turn the batteries back on again. Then
power up the inverter again. You may need to repeat this process up to three times to pre-charge the inverter
enough for it to power up.
