Setup and Installation
Unpacking and Inspection
Carefully unpack the inverter and inspect it for any shipping damage. Ensure all components listed in the packing list are present. If any damage or missing parts are found, contact your supplier immediately.
Mounting
Mount the inverter vertically on a sturdy wall in a well-ventilated area, away from direct sunlight, heat sources, and flammable materials. Ensure sufficient clearance (at least 20 cm) around the unit for proper airflow.
Wiring Diagram
Follow the diagram below for correct wiring connections. All wiring must comply with local electrical codes and standards.
Figure 2: Inverter Connection Diagram
The rear panel of the inverter provides the necessary connection terminals:
Figure 3: Rear Panel Connections
- PV Input: Connect solar panel strings to the PV+ and PV- terminals. Ensure PV input voltage does not exceed 500VDC.
- AC Input: Connect the utility grid or generator AC power to the AC IN terminals.
- AC Output: Connect your AC loads to the AC OUT terminals.
- Battery: Connect the 48V battery bank to the BATTERY POS+ and NEG- terminals.
- Communication Ports: RS232 and RS485 ports are available for monitoring and communication.
Battery Connection
The inverter is compatible with various 48V battery types, including lead-acid (FLD, SLD, AGM, GEL) and lithium (LI) batteries. It also supports user-defined battery parameters. The system can operate in batteryless mode under specific conditions.

Parallel Installation
For increased power output, up to 12 inverters can be connected in parallel. This supports single-phase, split-phase (120V/240V), and three-phase (120V/208V/240V) configurations. Ensure that share current cables and parallel cables are used for multi-unit installations.

Operating Instructions
LCD Display and Indicators
The inverter features an LCD screen and three LED indicators to display real-time system data, status, and error messages. Use the buttons below the LCD to navigate menus and configure settings such as battery charging current, AC/solar charger priority, and acceptable input voltage range.
Charging Modes
The inverter supports four distinct charging modes to optimize energy management:
Figure 6: Four Charging Modes
- Solar Only: Priority is given to solar charging. Mains charging will only start if solar power fails.
- Mains Priority: Priority is given to mains charging. Solar charging will only start if mains power fails.
- Solar Priority: Priority is given to solar charging. If solar PV energy is insufficient, mains power will supplement charging. Mains charging stops when solar PV energy is sufficient.
- Hybrid Charging (Mains & Solar): Both mains and solar power are used for charging, with user-configurable priority.
Output Modes
The inverter provides two primary output modes:
- Mains Bypass: When utility power is available and within acceptable limits, the inverter bypasses its internal circuitry and directly supplies AC power to the loads from the grid.
- Inverter Output: When utility power is unavailable or outside acceptable limits, the inverter converts DC power from the battery or solar panels into AC power to supply the loads.
Batteryless Operation
The inverter supports batteryless operation through its Anti-backflow Grid Connection feature, allowing for direct on-grid power generation from solar panels without requiring a connected battery bank.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your inverter.
- Regular Inspection: Periodically check all wiring connections for tightness and signs of corrosion. Inspect the inverter casing for any physical damage.
- Cleaning: Keep the inverter's ventilation openings clear of dust and debris. Use a soft, dry cloth to clean the exterior. Do not use liquid cleaners.
- Fan Operation: Ensure the cooling fans are operating correctly and are not obstructed. Excessive noise or lack of fan operation may indicate an issue.
- Battery Check: If using batteries, regularly check their terminals for corrosion and ensure they are properly charged and maintained according to the battery manufacturer's instructions.
Troubleshooting
This section provides solutions to common issues. For problems not listed here or if issues persist, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter does not power on | No DC input from battery/PV; DC breaker open; Loose battery connection. | Check battery voltage; Ensure DC breaker is closed; Tighten battery terminals. |
| No AC output | Overload; Short circuit; AC output breaker open; Inverter in fault mode. | Reduce load; Check for short circuits; Close AC output breaker; Check LCD for error codes and clear fault. |
| Battery not charging | PV input too low/high; AC input not present; Charging mode incorrect; Battery fault. | Check PV voltage; Verify AC input; Select correct charging mode; Inspect battery condition. |
| Over-temperature warning | Insufficient ventilation; Blocked cooling fans; High ambient temperature. | Ensure proper clearance; Clean fan vents; Relocate inverter to cooler environment. |
