Automatic Equalization

The C-Series controller can automatically trigger an equalization charge every 30 days. The status LED will indicate that the equalization process is occurring.

The equalization process will continue until the voltage has been held above the bulk setting for a cumulative period of two hours. This might take several days on larger systems with big batteries and small PV arrays. The battery voltage only needs to exceed the bulk setting for the timer to start counting–the voltage may not reach the equalization voltage setting.

To enable automatic equalization, the jumper located on the right side of the circuit board must be moved to the AUTO setting. The default setting of the C-Series controller is for manual equalization. To disable the automatic equalization system, move the equalize jumper to MANUAL.

Once a manual equalization has been triggered, the 30-day period to the next automatic equalization will be restarted. To prevent automatic equalization, move the equalize jumper to the manual position.

Important: It is not recommended to use the Equalization feature if the R46 Resistor is clipped.
