5. Installation and Setup
Proper installation is crucial for the safe and efficient operation of the inverter. It is recommended that installation be performed by a certified electrician.
5.1 Site Selection
- Install the inverter indoors, away from direct sunlight, moisture, and corrosive substances.
- Ensure the ambient temperature is within the operating range (refer to specifications).
- Provide at least 20 cm of clearance around the inverter for proper ventilation.
- Mount the inverter vertically on a sturdy surface.
5.2 Wiring Connections
Before making any connections, ensure all power sources (PV array, battery, AC grid) are disconnected and secured against accidental re-connection.
- Battery Connection: Connect the battery bank to the inverter's battery terminals. Ensure correct polarity (+ to + and - to -). The inverter requires a battery connection to operate.
- PV Array Connection: Connect the solar panel array to the inverter's PV input terminals. Observe correct polarity and ensure the PV input voltage is within the specified MPPT range (30-400 VDC) and does not exceed the maximum PV VOC (400 VDC). Recommended PV cable size is 16 AWG.
- AC Output Connection: Connect your household loads or distribution panel to the inverter's AC output terminals.
- AC Input Connection (Grid/Generator): If connecting to the utility grid or a generator, connect it to the inverter's AC input terminals.
- Grounding: Ensure the inverter is properly grounded according to local electrical codes.

6. Operating Instructions
6.1 Initial Power-Up
- After all connections are secure, switch on the battery breaker.
- Switch on the PV array breaker.
- Switch on the AC input breaker (if connected to grid/generator).
- The inverter will power on, and the LCD display will illuminate.
6.2 LCD Display and Settings
The LCD display provides real-time system information and allows for configuration of various parameters. Use the buttons below the display to navigate menus and adjust settings.
- Monitoring: View battery voltage, PV input voltage, AC output voltage, charging current, and load power.
- Charging Current: Adjust the battery charging current.
- Charger Priority: Set the priority for AC charger or solar charger.
- Input Voltage Range: Configure acceptable input voltage ranges for different applications.
6.3 Operating Modes
The inverter supports multiple charging and output modes to meet diverse user requirements:
- Solar Energy Priority: Solar power is primarily used to power loads and charge batteries. Utility power is used only when solar power is insufficient.
- Solar Energy + Utility Simultaneously: Solar power and utility power are used concurrently to power loads and charge batteries.
- Battery Only Charging: The inverter charges batteries from solar or utility, but does not directly power loads from these sources.

6.4 Remote Monitoring
Once the WiFi module is configured, you can monitor the inverter's performance and adjust settings remotely via a mobile application. This allows for real-time data access and control.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your inverter.
- Cleaning: Periodically clean the inverter's exterior with a dry cloth. Ensure ventilation openings are free from dust and debris. Do not use liquid cleaners.
- Connection Check: Annually inspect all electrical connections (PV, battery, AC) for tightness and signs of corrosion. Tighten any loose connections.
- Ventilation: Ensure the area around the inverter remains clear to allow for proper airflow and heat dissipation.
- Battery Inspection: If using batteries, follow the battery manufacturer's maintenance guidelines.
8. Troubleshooting
This section provides solutions to common issues. If the problem persists, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter does not power on. | No battery connection or low battery voltage. | Ensure battery is connected and charged. The inverter requires a battery to operate. |
| No AC output. | Overload, short circuit, or internal fault. | Reduce load. Check for short circuits in wiring. Restart inverter. If fault persists, contact support. |
| Inverter reports an error when load is connected. | Load exceeds inverter capacity, or specific load type incompatibility. | Ensure total load does not exceed 2000W. Some inductive loads (e.g., motors, refrigerators) have high startup currents; ensure the inverter's surge capacity (2000W) is sufficient. Try connecting a smaller, resistive load to test. |
| PV input not detected or low. | Insufficient sunlight, incorrect PV wiring, or PV voltage outside MPPT range. | Check solar panel connections and ensure adequate sunlight. Verify PV voltage is within 30-400 VDC. |
| Overheating warning. | Poor ventilation or excessive ambient temperature. | Ensure adequate clearance around the inverter. Clean ventilation openings. Reduce ambient temperature if possible. |
