BATTERY EQUALIZATION
Equalization mode is used for Flood and User-defined batteries.
Equalization is an advanced charging process of the inverter, designed to improve the performance and to extend the
life of a multi-battery string. By carrying out a controlled overcharge, it brings the batteries to a much higher voltage
than usual and maintains them there for a time. This removes inert lead sulfate compounds from the battery plates. It
also reduces stratification by circulating the electrolyte. If left unchecked, such conditions will degrade the capacity of
the batteries. Therefore, we recommend carrying out maintenance equalization cycles periodically.
• How to set up the equalization function
Battery equalization mode must be first enabled in item 33 of the LCD configuration screen.
Then, equalization can be either started manually or on an automatic “interval” basis. The available options are:
1. To program automatic equalization setpoints, access in item 37.
2. To carry out immediate equalization, manually activate the cycle in item 39.
• When to equalize
Once the interval setpoint (battery equalization cycle) is reached, or the equalization cycle is activated immediately in
float stage, the controller will initiate the equalization process.
• Equalization charging time and timeout
During this process, the controller will supply power to charge battery and hold it there until the voltage reaches the
set equalization point. Then, the timer will enter a constant voltage stage which requires the battery to be held at the
equalization level until the cycle time expires.
