Important: Inverter and charger voltage calibration:

Some inverters/chargers have been known to return inaccurate results when measuring voltage. In such cases, the inverter/charger should be calibrated as follows:

Compare the voltage values displayed by the inverter/charger with that of a calibrated voltmeter. If the actual voltage differs by more than 100mV from that measured by the inverter/charger, apply this difference to the highlighted values above (i.e. if actual voltage is 56V while inverter voltage is 56.5V, the voltage difference is 0.5V and should be subtracted from each of the set values above).

Note: Some inverters/chargers have pre-programmed lead-acid related algorithms & functionalities such as auto-desulfation and equalization. These functionalities should be disabled, where possible.

Serial Communication:

BlueNova® 52V RacPower batteries include serial communication functionality via CAN protocol. Serial-connecting a 52V NG battery to a compatible inverter, charger or other third-party hardware device normally negates the necessity of manual voltage-based installation procedures, as described above.

The installation procedure for serial integration varies and is determined by the serial-compatible peripheral hardware that is being integrated with.

Please note for Victron installations the DVCC must be switched on.


BlueNova batteries can be connected in parallel to each other to increase overall capacity ONLY IF ALL the requirements below are met.

  • The nominal voltage of all parallel connected batteries is the same (52V).
  • The installed capacity for all batteries is the same.
  • Each battery is operating within its warranty period.

A total of  9 units can be connected in parallel, for a total installed capacity of 46.8 kWh @C2 at 25 °C.

The Daily Use model also includes serial communication (CAN / RS485) functionality.
