D. INSTALLATION
1. VOLTAGE-BASED INSTALLATION
The following values highlighted in blue must be set on the inverter/charger:
Parameter
Cell V
Value
Comment
V high set
3.53 V
56.4 V
Typical bulk/absorption charge setpoint.
V float
3.44 V
55.0 V
Floating voltage set point.
V reconnect
3.06 V
49.0V
Mains or generator must reconnect to charge batteries.
V low set
2.9 V
46.5V
Inverter must switch off the load.
•Maximum Continuous Charge Current limit = 50 A
•Recommended Charge Current = 10 A
•Maximum discharge Current limit = 100 A
•Recommended discharge current limit = 50 A
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.

BlueNova® 52V RacPower batteries can be connected in parallel to each other to increase overall capacity ONLY
IF ALL the requirements below are met:
a. The nominal voltage of all parallel-connected batteries is the same (52V), and
b. The installed capacity for all batteries is the same, and
c. Each battery is operating within its warranty period.
A total of 6 units can be connected in parallel, for total installed capacity of 31.2kWh @C2, 25°C.
2.1 PARALLEL CONNECTION: STEP-BY-STEP INSTRUCTIONS
1. Ensure that all units are grounded by connecting each chassis to GROUND from the rear right panel.
Wire diameter should be equal to or exceed 1mm².
2. Connect the POSITIVE terminals of the first (top) unit to the second unit, then from the second unit to
the third etc. as illustrated above. Wire diameter should be equal to or exceed 8mm².
3. Connect the NEGATIVE terminals of the first (top) unit to the second unit, then from the second unit to
the third etc. as illustrated above. Wire diameter should be equal to or exceed 8mm².
4. Configure the dip switches for the master battery and slave batteries respectively.
5. Connect the RS485 ports of all parallel batteries with each other with a straight 1-to-1 pin RJ45 cable.
2.2 SWITCHING ON PARALLEL CONFIGURATIONS
1. After the system has been fully installed ensure that all the battery units are switched off.
All LED’s on the front panel should be off.
2. Switch on the first (master) unit. The rest of the batteries will then switch on automatically.
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. The battery needs to be charged every 6 months if out of use.
h. Ensure that the stored battery’s state of charge is always above 50%. 100% SOC is optimal.
i. Don’t place more than 6 units on top of each other.
F. TROUBLESHOOTING
Please cross-reference the behaviour of the battery’s LED indicators with the table below to determine whether
your battery is operating correctly. Kindly contact BlueNova Technical Support for assistance if necessary.
