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.
