Choose a solid, non-flammable surface for mounting. Install the inverter at eye level for easy LCD display reading. Ensure the ambient temperature is between -10°C and 60°C. Maintain at least 30cm clearance on all sides for heat dissipation and wiring access.
- Drill holes using an Ø8 drilling bit with 110mm spacing. Insert M6 expansion screws.
- Align the inverter's top screw holes with the expansion screws and fix it to the wall.
- Before connecting wires, remove the bottom cover by unscrewing the four screws.
2.4 AC Input / Output Connection
WARNING! All AC wiring must be performed by qualified personnel and comply with local electrical safety standards. Install a separate AC breaker (recommended 80A) between the inverter and the AC input power source.
CAUTION! Do not mis-connect AC IN, AC OUT1, and AC OUT2 terminals. Ensure correct polarity (L and N wires) to prevent utility short-circuits in parallel operation.
Recommended AC wire gauge:
- AC OUT1 (Max 70A): 6 AWG (13.3 mm²)
- AC OUT2 (Max 40A): 10 AWG (5.26 mm²)
Steps for AC connection:
- Open the AC circuit breaker first.

- Ensure all cables are securely connected.
2.5 PV Connection
WARNING! Install a separate DC circuit breaker between the inverter and PV modules. Do not ground positive or negative PV terminals. Exposure to sunlight generates lethal high voltages; adhere to safety precautions. Connect PV terminals to corresponding ports on the inverter; reversing polarity can damage the inverter. All wiring must be performed by qualified personnel.

4. Maintenance
4.1 Battery Equalization
The equalization function helps reverse the buildup of negative chemical effects like stratification and removes sulfate crystals from battery plates, which can reduce battery capacity. It is recommended to equalize batteries periodically.
Note: Do not activate this mode when using lithium batteries.
How to Apply Equalization Function:
You can enable battery equalization in Program 32 (Charging Time Setting) or choose immediate equalization in Program 35. Then, configure the following settings:
- Set equalization voltage point on Program 31.
- Set equalization charging time on Program 32.
- Set equalization delay time on Program 33.
- Set equalization interval time on Program 34.
- Set immediate equalization mode activation on Program 35.
When to Equalize:
In float stage, when the set equalization interval is reached, or equalization is active immediately, the controller will enter the Equalize stage.
During the Equalize stage, the controller charges the battery until the battery voltage reaches the equalization voltage. It then maintains constant voltage regulation. The battery remains in this stage until the set equalization time is reached.
If the battery equalization time expires and the voltage hasn't reached the set point, the charge controller will extend the time until it reaches the voltage. If the voltage is still below the set point after the extended time, the controller will stop equalization and return to the float stage.
5. Troubleshooting
5.1 Fault Reference Code
When a fault occurs, the fault indicator (red LED) is always on, and the buzzer sounds for 10 seconds then stops. The system attempts to restart automatically. If it fails after six attempts, the machine and LCD will remain in fault status. You must completely power off the unit or wait 15 minutes to restart.

7. User Tips
- Inductive Load Considerations: The starting power of inductive load electrical appliances should be at least three times their rated power. Ensure your inverter's power capacity is sufficient for the starting power of connected appliances to prevent damage.
- Batteryless Operation: Yes, the inverter can operate without a battery, powering loads directly from PV or AC sources.
- Grid Feedback: The inverter supports grid-tie functions. Excess solar energy can be fed back into the grid, depending on the selected operating mode (e.g., PGB mode).
- Optimal System Setup: For stable operation and electricity bill savings, connecting a battery is recommended. When the mode is set to SBU (Solar-Battery-Utility), the system prioritizes PV and battery power before drawing from the utility grid.
8. Warranty and Support
For any warranty claims, technical support, or repair services, please contact your local distributor or the manufacturer directly. Ensure you retain your purchase records for warranty validation.
