4. Safety Information
- Always install circuit breakers for all lines connected to the inverter.
- Do not connect or disconnect lines while power is applied to the system. Ensure all power sources are disconnected before performing any wiring or maintenance.
- Be aware of high voltage. The inverter system operates at high voltages which can be dangerous.
- When connecting inductive load appliances (e.g., refrigerators, washing machines, air conditioners), ensure the inverter's power rating is at least three times the total power of these appliances to prevent damage and ensure proper startup.
- Follow the correct connection sequence as per the installation instructions.

- A: No, this inverter model is not designed for series or parallel connection.
- Q: What types of batteries can be used?
- A: Lead-acid batteries, gel batteries, Lithium Iron Phosphate (LiFePo4), and other lithium batteries can be used. For the 3.6KW model, a 24V battery system is required. For the 6.2KW model, a 48V battery system is required. The battery capacity should not be less than 100AH.
- Q: Can it be used with air conditioners, water pumps, and wind turbines?
- A: It can be used with air conditioners. However, it is not suitable for use with water pumps and wind turbines.
- Q: Is it possible to use PV, battery, and grid supply at the same time?
- A: Yes. The default mode is PV priority. When the PV input is insufficient, the system will automatically utilize power from the battery and utility grid.
9. User Tips
- The output frequency of the inverter can be configured to either 50Hz or 60Hz, depending on your regional requirements.
- When connecting household appliances with inductive loads (e.g., refrigerators, washing machines, air conditioners), ensure the inverter's power rating is at least three times the total power of these inductive loads. This prevents potential damage to the inverter and ensures proper startup of the appliances.
- Take advantage of the smart monitoring feature via the dedicated app, available for both iOS and Android systems, to check the running status of your inverter remotely.
