Maximum charging / discharging voltages for non supported devices.

Bulk charge (stop charging)

54.6V

Float charge (if applicable)

53.8V

Low battery discharge:

48V

Check that the Equalisation function are disalled, then verify if there is a voltage difference on
the inverter display and the battery terminals @0.3C discharge / charge current. If so adjust

the values above.

Please check if your inverter charger has been approved by Solar MD and it is CAN
compatible.
