The battery manufacturer should be consulted. Clean, distilled water will need to be added to the
battery AFTER the equalization process.
4.2.1 Automatic Equalization Charging
Automatic Equalization charge is only available when battery voltage is higher than the Low
Voltage Disconnect (LVD) voltage , see 4.3.1.
To set Automatic Equalization Charging, set the dip switch 2 to OFF position
.
The PV Charge Controller will perform Equalization charging for 2 hours once every 30 days
During equalization charge , it can be stopped any time by pressing the Reset button
once and
