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.
