Operating Modes
The inverter offers flexible charging and load output modes to optimize energy usage based on your preferences and available power sources.
Charging Modes
There are four selectable battery charging modes:
Figure 5: Visual representation of the four battery charging modes: Solar Charging, Electricity Utility Priority, Solar Priority, and Hybrid Charging.
- Only Solar: Battery is charged exclusively by solar power.
- Utility Priority: Utility power is prioritized for charging; solar charges only when utility is unavailable.
- Solar Priority: Solar power is prioritized for charging; utility charges only when solar is insufficient.
- Utility & Solar Hybrid Charging: Both utility and solar power are used for charging.
Load Output Working Modes
Three load output working modes are available:

- PV Priority: Solar power is prioritized to supply the load.
- Utility Priority: Utility power is prioritized to supply the load.
- Inverter Mode: The inverter supplies power from the battery.
LCD Display and Indicators
The LCD display and LED indicators provide real-time system data and operational status. Users can access and modify over 20 programmable parameters, including input/output voltage range, battery charging current, battery type, and charging/discharging priority.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your PowMr Solar Inverter. Perform the following checks periodically:
- Cleaning: Keep the inverter's ventilation openings clear of dust and debris to ensure proper airflow and cooling. Use a soft, dry cloth for cleaning the exterior.
- Connection Checks: Periodically inspect all electrical connections (PV input, battery, AC input/output) for tightness and signs of corrosion. Loose connections can lead to overheating and performance issues.
- Environmental Conditions: Ensure the inverter is installed in a well-ventilated area, away from direct sunlight, moisture, and flammable materials. Maintain the recommended operating temperature range.
- Firmware Updates: Check the manufacturer's website for any available firmware updates that may improve performance or address known issues.
Troubleshooting
This section provides guidance on common issues you might encounter with your solar inverter. For complex problems, contact technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter not turning on / No display | No DC input from battery or PV; loose battery connections; AC input breaker tripped. | Check battery voltage and connections. Ensure PV input is sufficient. Reset AC input breaker. |
| No AC output | Overload; short circuit; low battery voltage; inverter in fault mode. | Reduce load. Check for short circuits. Charge battery. Check LCD for fault codes and refer to manual. |
| Battery not charging | PV input too low; AC input unavailable (if utility charging); incorrect charging mode setting. | Ensure sufficient solar irradiance. Verify AC input. Check and adjust charging mode settings (e.g., "Only Solar", "Utility Priority"). |
| Fan noise / Fan error | Normal operation under load; obstructed fan; internal wiring issue. | Fan noise is normal during high load or high temperature. Check for obstructions. If persistent error, contact support. |
| Inverter frequently switches between modes | Incorrect battery voltage setpoints for mode switching. | Review and adjust "Battery Power to Utility Setpoint" ([04]) and "Utility to Battery Power Setpoint" ([05]) in the inverter settings. Ensure "Battery Undervoltage Alarm" ([14]) is set appropriately. |
