6. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your inverter. Follow these steps carefully.
6.1 Mounting the Inverter
- Choose a suitable location: Select a cool, dry, and well-ventilated area, away from direct sunlight, flammable materials, and moisture. Ensure sufficient clearance around the inverter for air circulation.
- Secure mounting: Use appropriate screws and anchors to securely mount the inverter to a solid surface. The inverter can be mounted vertically or horizontally.
6.2 Electrical Connections
Before making any electrical connections, ensure all power sources are disconnected.
- DC Input Connection (Solar Panels):
- Connect the positive (+) cable from your solar panel array to the red DC input terminal on the inverter.
- Connect the negative (-) cable from your solar panel array to the black DC input terminal on the inverter.
- Ensure the DC input voltage from your solar panels is within the inverter's MPPT voltage range (22V-50V) and does not exceed the maximum input voltage (50V).
- AC Output Connection (Grid/Load):
- Connect the AC output cables from the inverter to your electrical panel or load, ensuring correct phase, neutral, and ground connections.
- Install the provided circuit breaker in the AC output line as a protective measure.
- The inverter provides integrated grounding via the PE wire in the AC cable.
- Antenna Installation:
- Screw the provided antenna onto the designated antenna port on the inverter for WiFi communication.

7. Operating Instructions
Once installed, the inverter is ready for operation. This section covers basic startup and monitoring.
7.1 Initial Startup
- Verify Connections: Double-check all DC and AC connections to ensure they are secure and correct.
- Apply DC Power: Connect the solar panels to the inverter. The inverter will automatically start when sufficient DC voltage is detected.
- Apply AC Power: Turn on the circuit breaker connected to the inverter's AC output. The inverter will synchronize with the grid and begin power generation.
7.2 Tuya APP Remote Monitoring
The inverter supports remote monitoring via the Tuya APP, allowing you to track performance and manage settings from your smartphone.
- Download the Tuya APP: Search for "Tuya Smart" or "Smart Life" in your mobile app store (iOS or Android) and install it.
- Register/Log In: Create a new account or log in to your existing Tuya account.
- Add Device:
- Ensure your smartphone is connected to a 2.4GHz Wi-Fi network.
- Open the Tuya APP, tap the "+" icon to add a device.
- Select "Electrical Engineer" or "Power Strip" (or similar category for inverters/power devices).
- Follow the in-app instructions to connect the inverter to your Wi-Fi network. This typically involves putting the inverter into pairing mode (refer to the inverter's display or indicator lights for specific instructions, if available).
- Monitor and Control: Once connected, you can view real-time power generation, energy consumption, historical data, and adjust operational modes (e.g., grid-tied, reverse termination) directly from the app.
8. Maintenance
Regular maintenance ensures the longevity and optimal performance of your inverter.
- Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Do not use liquid cleaners or solvents. Ensure cooling vents are free from dust and debris.
