5.4 Battery Equalization Description Equalization function is added into charge controller, lt 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: 1. Setting equalization interval in program 35. 2. Active equalization immediately in program 36 When to Equalize in stage, when the setting equalization interval( battery equalization cycle) is arrived, or equalization is active immediately, the controller will start to enter Equalize stage.

Explanation: STG:Battery SOC turn to grid mode. The default setting is 50, and the settable range is [10,90]. PBG priority Mains normal battery mode Switch to mains mode when the lithium battery SOC reaches the set value. After it is turned on, when the SOC is lower than the set point or the battery voltage is lower than the return-to-mains voltage point (see 1.4.2.14), the inverter will switch to the mains mode.it can be set to OFF. At this time, the inverter will no longer switch from battery mode to mains mode according to the SOC. After the function is enabled, if a communication abnormality occurs, the inverter no longer determines the operation logic based on the SOC information, and clears the relevant alarm.When this setting is higher than the STB point, STB and STG will not take effect after the next time they take effect. This function needs to be used in conjunction with the central control board. When the central control board is not connected, this option page is blocked.

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.
38

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. lf 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

Appendix:Parallel Operation Guide
Parallel operation Note: Before paralleling, each machine needs to calibrate the inverter output voltage, DC component, and battery voltage. In theory, The more accurate the calibration, the better, but at least meet the inverter output voltage and battery voltage calibration deviation within ±0.3V, DC component calibration within ±50 mV.
The shutdown state, that is, the standby state, refers to the state in which the inverter has no output, but the LCD screen is on.
The method of entering standby state: when the switch is closed, quickly turn on and then immediately (1 second) turn off, then the inverter enters the standby state.

2.Connection Precautions 2.1 PV connection/Solar Panel Connection Each inverter is connected to the solar panel separately, and the PVs of each inverter cannot be wired in parallel. 2.2 Parallel board connection Note: In each set of parallel systems, select the two sets of machines with the farthest distance and short-circuit the positions A of the parallel board with jumper caps.

Make sure all circuit breakers in the load side line are open And each neutral line (N line) of the inverter is connected together, and the live line (L line) at the load side should also be connected together. Step 2-1: Close the battery breaker (between inverter and battery) then quickly make the inverter switch from power ON to OFF. Step 2-2: You will have 30 seconds to setting in LCD panel,
if LCD panel off,just repeat the Step 2-1,then step2-2. Step 2-3: Go into Inverter setting mode and set “PAR” in program 27 on the LCD. Then turn off all inverters. Note: When setting on the LCD, the power-ON switch must be turned off. Otherwise, settings cannot be made and AC input breaker is not allow to close.

3.LCD Setup and Display For the parallel setting operation, refer to the main manual – function setting operation, item 27 parallel mode setting. 3.1 Single-phase parallel Step 1: Before commissioning, please check the following requirements:ls the wiring correct?
51

Notice: Automatic identification of primary and secondary inverters in the system Step 3: Close the AC circuit breakers of all lines in the AC input, keep the rocker switch not closed, and wake up the parallel system. There are instructions on the next page of P9 on the LCD display interface, as shown in Figure 4.1.1. It is best to have all inverters connected to mains at the same time. If not, it will show fault 23 or 22. Step 4: If there are no more fault alarms and the indicating interface is normal, the parallel system is fully installed. Step 5: Close the circuit breaker on the load side. Turn on the system and start supplying power to the load.

3.2 Parallel as three-phase system (the function is not open) Step 1: Before commissioning, please check the following requirements: Is the wiring correct? Make sure that all circuit breakers on the load side are disconnected, and the neutral wires (N/neutral) of each inverter are connected together, the live wires (L wires) on the load side of the same phase are connected together, and the different phases are connected together. The live wires (L wires) are not connected together. Confirm that the output inverter voltage of each machine, the DC component and the battery voltage are all successfully calibrated. Step 2: Wake up the inverter to put it into shutdown state, Step 2-1: Close the battery breaker (between inverter and battery) then quickly make the
inverter switch from power ON to OFF.
Step 2-2: You will have 30 seconds to setting in LCD panel,
if LCD panel off,just repeat the Step 2-1,then step2-2.
then use program 27 on the LCD to configure each Inverter as 3P1, 3P2, 3P3 in turn. When using the LCD for program setting, the power-on switch must be turned off. Otherwise, settings cannot be made and AC input breaker is not allow to close.

Figure 4.1.2
Note 1: To avoid overloading, it is best to let the whole system operate normally before closing the circuit breaker on the load side. Note 2: There is a switching time for this power supply system. Power outages may occur for critical equipment with high power requirements.

Step 3: Turn on the AC circuit breakers for all lines in the AC input. If an AC connection is detected and matches the device settings, the system is working properly. Otherwise, The system will display an alarm or fault, and will not operate in mains mode. Step 4: Close the AC circuit breakers of all lines in the AC input, keep the rocker switch not closed, and wake up the parallel system. There are instructions on the next page of P9 on the LCD display interface, as shown in Figure 4.1.2, which means three-phase power supply System installation is complete. Step 5: Please close the circuit breakers of all power lines on the load side, close the rocker switch, and the system will start supplying power to the load.
