4.7. Battery Equalization
Equalization function is added into the charge controller. It reverses the buildup of negative chemical effects like stratification, a condition where acid concentration is greater at the bottom of the battery than at the top. Equalization also helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this condition, called sulfation, will reduce the overall capacity of the battery. Therefore, it's recommended to equalize battery periodically.
How to Apply Equalization Function:
You must enable battery equalization function in monitoring LCD setting program 30 first. Then, you may apply this function in device by either one of following methods:
- Setting equalization interval in program 35.
- Active equalization immediately in program 36.
When to Equalize:
In float stage, when the setting equalization interval (battery equalization cycle) is arrived, or equalization is active immediately, the controller will start to enter Equalize stage.
Graph: Battery Equalization stages including Bulk, Absorption, Float, and Equalize.
Equalize Charging Time and Timeout:
In Equalize stage, the controller will supply power to charge battery as much as possible until battery voltage raises to battery equalization voltage. Then, constant-voltage regulation is applied to maintain battery voltage at the battery equalization voltage. The battery will remain in the Equalize stage until setting battery equalized time is arrived.
Graph: Battery Equalization Charging Time and Timeout.
4.8. Mains and Lithium Battery Activation Function
- After 90s of mains power connection to the inverter, the machine is connected to the mains and starts to work.
- The inverter is in lithium battery mode (item 05 is Llb or Llb-485). After the mains is connected, the battery is not connected, and the mains activation function is automatically enabled.
5. Maintenance
5.1. Clearance and Maintenance for Anti-Dust Kit
