4. Installation and Wiring
Proper installation and wiring are crucial for the safe and efficient operation of your inverter. Refer to the following steps and diagrams.
4.1 Unboxing and Initial Inspection
Upon receiving your inverter, carefully unbox it and inspect for any physical damage. Ensure all components listed in the packing list are present.
4.2 Wiring Instructions
Before connecting any wires, ensure the inverter is turned off and disconnected from all power sources. Open the cover plate by removing the screws to access the wiring terminals.
- **Connect the Battery**: Connect the positive (+) and negative (-) terminals of your battery bank to the corresponding BATTERY terminals on the inverter. Ensure a secure connection.
- **Connect the PV Panels**: Loosen the screws for the PV IN terminals and connect the positive (+) and negative (-) wires from your solar panel array. Tighten the screws securely.
- **Connect the Ground Wire**: Connect the ground wire to the COMM terminal.
- **Connect AC Input/Output**: Connect the AC input (utility grid) and AC output (loads) wires to the respective AC IN and MAIN OUT/SECOND OUT terminals. Ensure correct line (L) and neutral (N) connections.
After completing all wiring, close the cover plate and secure it with screws.
5. Operating Instructions
5.1 Starting the Inverter
Follow this sequence to safely start the inverter:
- Turn on the battery switch.
- Turn on the inverter using its power switch.
- Once the inverter is working, turn on the PV input, mains (AC input), and load switches.
Attention: AC and PV inputs can only be turned on after the inverter is working. Otherwise, the unit may be damaged easily.
5.2 Monitoring and Settings
The LCD display allows you to view various operational data and configure inverter settings. Use the function buttons (up, down, enter) to navigate through the menus.
Models with WiFi functionality allow for remote monitoring and control via a dedicated app for iOS and Android devices.
5.3 Load Output Modes
The inverter supports three load output modes:
- **Utility First (USB)**: Utility power is the primary source for loads. Solar power and battery energy will only supply power when utility power is unavailable.
- **Solar First (Default - SUB)**: Solar energy is the primary source for loads. If solar energy is not sufficient to power all connected loads, utility power will supplement. Battery power is used next if both solar and utility are insufficient.
- **SBU Priority (SBU)**: Solar energy is the primary source for loads. If solar energy is not sufficient to power all connected loads, battery energy will supplement. Utility power is used last if both solar and battery are insufficient.
5.4 Operation with/without Battery
The AN-SCI-ECO-4200 and AN-SCI-ECO-6200 models can operate with or without batteries. The AN-SCI-ECO-2000 and AN-SCI-ECO-3200 models require a battery to operate.
5.5 Shutting Down the Inverter
Follow this sequence to safely shut down the inverter:
- Turn off the switches for the load, PV input, and mains (AC input).
- Turn off the inverter using its power switch.
- Finally, turn off the battery switch.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your inverter.
- **Cleaning**: Periodically clean the exterior of the inverter and ensure ventilation openings are free from dust and debris. Use a dry cloth for cleaning.
- **Connection Checks**: Regularly inspect all wiring connections (battery, PV, AC input/output, ground) to ensure they are tight and free from corrosion.
- **Environmental Conditions**: Ensure the operating environment maintains the specified humidity (5% to 95% Relative Humidity, non-condensing) and temperature (–10°C to 50°C).
- **Battery Health**: Monitor battery health and charge levels. Ensure the battery type is compatible and correctly configured in the inverter settings.
7. Troubleshooting

10. User Tips
- **Battery Compatibility**: The inverter is compatible with Lead-acid, Gel, AGM, Lithium Iron Phosphate (LiFePo4), and Lithium batteries. Ensure the battery voltage matches the inverter's requirements (e.g., 24V for 3.6KW/4.2KW, 48V for 6.2KW) and the capacity is not less than 100AH.
- **Inductive Loads**: When connecting inductive loads like refrigerators or air conditioners, ensure the inverter's power rating is at least three times the appliance's starting power to prevent operational issues.
- **Simultaneous Power Sources**: The inverter can utilize PV, battery, and grid supply simultaneously. The default mode prioritizes PV.
- **AC Output Voltage**: Note that the inverter provides 220V/230V/240V AC output. If your region uses 110V AC, a step-down transformer or a different inverter model may be required as these models do not support 110V output.
- **WiFi Module**: Some models come with a WiFi module for remote monitoring. Verify your model's specifications if this feature is desired.
- **PV Input for 2000W/3200W Models**: The upgraded 2000W and 3200W models can operate with an open-circuit voltage of the solar panel higher than 35VDC, and a stable input of 30VDC is sufficient, eliminating the need for a continuous 90VDC input like some other series.
