Operation
7.1
To Turn the Battery Module ON and OFF
To turn the battery module on, move the circuit breaker ‘up’. This will energise the POWER IN/OUT J1
connector. It will also activate the green LED on the front panel.
To turn the battery module off, move the circuit breaker ‘down’. This will de-energise the POWER
IN/OUT J1 connector. It will also de-activate the green LED on the front panel.
If the green LED does not illuminate when the circuit breaker is in the ‘ON’ position, go to the
trouble shooting section of this manual.
7.2
Power in/out J1
The DC power to the J1 connector is floating. Neither the positive nor the negative is connected to the
modules chassis. DC from the battery module is floating.
When the circuit breaker is in the OFF position, as the circuit breaker is dual pole, both the positive
and negative is isolated from the battery pack inside the module casing
7.3
Charging the Battery Module
These battery modules should only be charged by an approved charger that is designed to charge LFP
chemistry, at the correct voltage, current and charge profile.
The charging profile described below is designed to achieve maximum number of cycles/life of the
battery module.
7.3.1
Operating temperature
An ambient temperature of 23 to 27 Celsius is the ideal temperature for the operation of the battery.
Operating outside of these temperatures will affect cycle life, capacity and possibly the warranty.
7.3.2
Charging current
Commence a charge cycle where the current is limited (Constant Current or CC) at 0.5C
19.2 Amps (for model GC48V-040LFP-2RU)
28.8 Amps (for model GC48V-060LFP-2RU)
7.3.3
Balance voltage
Applicable to all models of 48V modules
Charge the battery module at a Constant Current until the module voltage reaches 57.6 Volts.
Continue charging at a constant voltage of 57.6 Volts for two (2) hours. This will then allow the cells
to ‘balance’ their terminal voltage.
After two hours, the charging voltage can be removed as the module should now be fully charged.
At the completion of the above charge profile, the battery can either be stored or placed on a float
charge.
