Charge Algorithm
The charging process involves three phases:
- Boost CC (constant current level): If AC input is applied, the charger runs at full current until the boost voltage is reached.
- Boost CV (constant voltage level): The charger maintains the boost voltage until a timer expires, then drops to the float voltage when charging current falls below 20% of the set value.
- Float (constant pressure level): In float mode, the voltage stays at the float voltage. If AC is reconnected or battery voltage drops below 12Vdc/24Vdc/48Vdc, the charger resets the cycle.

MPPT Charger Controller Matching
In application systems, MPPT controllers and inverters charge batteries simultaneously. To prevent unsafe situations from excessive charging current, a matching function is included to protect the battery more effectively and manage charging scientifically.
NOTE: The inverter and MPPT controller must be from the same manufacturer for compatibility. The maximum continuous charging current should not exceed 30% of the battery capacity (e.g., for a 48V 200AH battery pack, the current should be less than 60A).
Main Functions of Matching
- Enable or disable the inverter to match the MPPT function. (Special note: When upgrading inverter firmware, disable the MPPT matching function first).
- Limit the inverter charging current. This is managed based on the MPPT charging current relative to the inverter's limit.
Matching the Inverter to the MPPT Controller
- Ensure the inverter and MPPT controller are powered on and communication lines are connected.
- Press and hold the "Down" button on the inverter for over 2.5 seconds until the MPPT charger icon flashes. Release the button.
- The flashing icon indicates the inverter is attempting to communicate with the MPPT. The icon will stop flashing after 10 seconds. Successful communication means the function is enabled.
- Once enabled, the matching MPPT function flag is saved in EEPROM. The inverter does not need manual re-enabling after a restart.
- After successful enabling, PV voltage, power, and other MPPT information will be displayed when cycling through the LCD screen.
Matching MPPT Function is Prohibited
- To prevent matching, turn off the MPPT or disconnect the communication.
- Press and hold the "Down" button for over 2.5 seconds until the MPPT charger icon flashes. Release the button.
- The icon stopping flashing after 10 seconds indicates successful prohibition. Failure to communicate also signifies prohibition.
- The matching MPPT function flag is saved in EEPROM. Restarting the inverter will maintain the prohibited status.
- After successful prohibition, MPPT information will no longer be displayed on the LCD.
Action and LCD Display Examples
Matching MPPT Function Enable/Disable
| Action | Instruction | LCD Display |
|---|---|---|
| Match MPPT function enable | Long press "Down" button until the icon in the red box flashes, indicating communication attempt. Icon stops flashing after 10 seconds. |  |
| Match MPPT function is prohibited | Long press "Down" button until the icon in the red box flashes. Icon disappears after 10 seconds. |  |
Matching MPPT Function Successfully Enabled
| Action | Instruction | LCD Display |
|---|---|---|
| If MPPT is in charging state: When the MPPT function is successfully enabled, the icon in the red box will appear. | | |
| If MPPT is not in charging state, but PV voltage > 30V and in startup state: When the MPPT function is successfully enabled, the icon in the red box will appear. | |
Matching MPPT Function is Prohibited Successfully
| Action | Instruction | LCD Display |
|---|---|---|
| When the matching MPPT function is prohibited successfully, MPPT icon information will no longer be displayed. | |
Whether matching MPPT function enables judgment
- If the MPPT function is enabled, the LCD interface page turning will display PV voltage, power, and other information.
- If the matching MPPT function is prohibited, the LCD interface page turning will not display PV voltage, power, and other information.
