4. BATTERY EQUALIZATION
The 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, the condition, called sulfation, will reduce the overall capacity of the battery. Therefore, it is recommended to equalize the battery periodically.
- How to Apply Equalization Function
You must enable the battery equalization function in the monitoring LCD setting program 33 first. Then, you may apply this function in the device by either one of the following methods:
Setting the equalization interval in program 37.
Activating equalization immediately in program 39.
- When to Equalize
In the float stage, when the set equalization interval (battery equalization cycle) is reached, or equalization is activated immediately, the controller will start to enter the Equalize stage.
● Equalize charging time and timeout
In the Equalize stage, the controller will supply power to charge the battery as much as possible until the battery voltage rises to the battery equalization voltage. Then, constant-voltage regulation is applied to maintain the battery voltage at the battery equalization voltage. The battery will remain in the Equalize stage until the set battery equalized time is reached.
However, in the Equalize stage, when the battery equalized time expires and the battery voltage does not rise to the battery equalization voltage point, the charge controller will extend the battery equalized time until the battery voltage achieves the battery equalization voltage. If the battery voltage is still lower than the battery equalization voltage when the battery equalized timeout setting is over, the charge controller will stop equalization and return to the float stage.

- Before starting setting, you must get the battery BMS specification:
A. Max charging voltage B. Max charging current
C. Discharging protection voltage
- Set battery type as "USE" (user-defined)
| 05 | Battery type | AGM (default) | Flooded |
User-Defined | If “User-Defined” is selected, battery charge voltage and low DC cut-off voltage can be set up in program 26, 27 and 29. |
- Set C.V voltage as Max charging voltage of BMS - 0.5V.
| 26 | Bulk charging voltage (C.V voltage) | default setting: 56.4V |
| If self-defined is selected in program 5, this program can be set up. range is from 24.0V to 31.0V for 24v model and 48.0V to 62.0V for model. But the setting value must be more than or equal the value of program27. Increment of each click is 0.1V. |
- Set floating charging voltage as C.V voltage.
| 27 | Floating charging voltage | default setting: 54.0V |
| If self-defined is selected in program 5, this program can be set up. Setting range is from 24.0V to the value of program 26 for 2 model and 48.0V to the value of program 26 for 48v model. Increment of each click is 0.1V. |
- Set Low DC cut-off voltage ≥ discharging protection voltage of BMS + 2V.
| 29 | Low DC cut-off voltage | default setting: 42.0V |
| If self-defined is selected in program 5, this program can be set u Setting range is from 20.0V to 27.0V for 24v model and 40.0V to 54.0V for 48v model. The setting value must be less the value of program12. Increment of each click is 0.1V.Low DC cut-off voltage will be fixed to setting value no matter what percent of load is connected. |
- Set Max charging current which must be less than the Max charging current of BMS.
| 02 | Maximum charging current: To configure total charging current for solar and utility chargers. (Max. charging current = utility charging current + solar charging current) | 60A (default)  | If selected, acceptable charging current range will be within 1-Max. charging current of SPEC, but shouldn't be less than the AC charging current ( program 11 |
- Setting voltage point back to utility source when selecting "SBU priority" or "Solar first" in program 01. The setting value must be ≥ Low DC cut-off voltage + 1V, or else the inverter will have a warning as battery voltage low.
| 12 | Setting voltage point back to utility source when selecting “SBU priority” or “Solar first” in program 01. | Available options in 48V models: 46V (default) |
Available options in 24V models: 23V (default) |
It is better to finish the settings without turning on the inverter (just let the LCD show, no output); when you finish the settings, please restart the inverter.
