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 33 first. Then, you may apply this function in device by either one of following methods: 1. Setting equalization interval in program 37. 2. Active equalization immediately in program 39. 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. 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. However, in Equalize stage, when battery equalized time is expired and battery voltage doesn't rise to battery equalization voltage point, the charge controller will extend the battery equalized time until battery voltage achieves battery equalization voltage. If battery voltage is still lower than battery equalization voltage when battery equalized timeout setting is over, the charge controller will stop equalization and return to float stage. 38 SPECIFICATIONS Table 1 Line Mode Specifications MODEL Input Voltage Waveform Nominal Input Voltage Low Loss Voltage Low Loss Return Voltage High Loss Voltage High Loss Return Voltage Max AC Input Voltage Max AC Input Current Nominal Input Frequency Low Loss Frequency Low Loss Return Frequency High Loss Frequency High Loss Return Frequency Output Short Circuit Protection Efficiency (Line Mode) Transfer Time Output power de-rating: When AC input voltage under 170V the output power will be de-rated.
