IMPORTANT: Inverter/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 = 56V while inverter voltage = 56.5V,
the voltage difference = 0.5V 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 equalisation. These functionalities should be disabled, where possible.

2. SERIAL COMMUNICATION
BlueNova® HC batteries include serial communication functionality via CAN protocol. Connecting a BlueNova®
HC battery to a compatible inverter, charger or other third-party hardware device normally negates the necessity
of manual voltage-based installation procedures, as described in the section above.
The installation procedure for serial integration varies and is determined by the serial-compatible peripheral
hardware that is being integrated with.
3. PARALLEL CONNECTION
BlueNova batteries with 123Smart firmware version 5.4 & higher as well as BMMC firmware version 2.5 & higher
include MultiCap™ technology. Batteries with MultiCap™ can be connected in parallel to each other to increase
overall capacity, regardless of the age difference and/or rated capacity difference between any two of the
batteries in the parallel configuration ONLY IF ALL of the requirements below are met:
a. The nominal voltage of all parallel-connected batteries is the same (i.e. 52V), and
b. The installed capacity @C10 of the largest battery in the parallel configuration is no larger than 4 x the
installed capacity @C10 of the smallest battery in the same configuration, and
c. The correct firmware versions are installed on all batteries in the configuration & updated accordingly, and
d. Each battery is operating within its warranty period.
Parallel-connected battery configurations should always be connected to the inverter/charger from both ends of
the configuration, as illustrated in either of the 2 x examples below:

E. MAINTENANCE
1. General Guidelines
a. Do not short circuit the battery terminals.
b. Do not use the battery without a BlueNova® approved integrated BMS solution.
c. Do not disassemble, pierce, cut or in any way physically alter any part of the battery.
d. Do not burn, incinerate or otherwise subject the battery to extreme heat.
2. Storage Instructions
a. Ensure that the battery is switched off when stored.
b. Disconnect the communication cable.
c. Always store batteries in a cool and well-ventilated area –ideally 25°C ± 3°C.
d. Store away from moisture and heat.
e. Do not store batteries upside down for overly long periods.
f. Check the open circuit voltage of stored batteries at least once per month. Recharge batteries sufficiently and
frequently enough to prevent the open circuit voltage falling below 40V.
g. Ensure that the stored battery’s state of charge is always above 50%. 100% SOC is optimal.

Fuse Error
1. Check fuse(s) & terminal connections.
2. Power cycle the battery (switch off, then on again).
2. Recovery from over-discharge
BlueNova® batteries will automatically disconnect from the inverter/charger if the battery is over-discharged
to the point that the cell voltage over any single cell reaches 2.85V. For BlueNova’s 52V NG range, the
integrated electronics that drive the OLED display will remain operational while the total battery voltage
remains above 40V (2.5V x 16 cells).
If an over-discharged battery’s total voltage falls below 40V, the battery will automatically enter DDL (Deep
Discharge Lockout) mode. Recovery from DDL mode might still be possible, depending on how long the
battery has remained in this state. Please contact BlueNova Technical Support in such cases.
If an over-discharged battery’s display is still operational, the battery can be recovered from this state by
following the procedure below:
