6.2 Charging Modes
The inverter offers four optional battery charging modes to suit different energy management strategies:
Figure 8: Four selectable battery charging modes.
- Solar First: Priority is given to charging by PV. Mains charging will only start if PV fails.
- Mains First: Priority is given to charging by Mains Power. PV charging will only start if Mains Power fails.
- Hybrid Charging: Hybrid charging of PV and Mains Power. Priority is given to PV MPPT charging, with Mains Power supplementing if PV energy is insufficient.
- Only Solar: Only PV charging is initiated; no mains charging occurs.
6.3 AC Output Modes
The inverter provides four AC output working modes for diverse application needs:
Figure 9: Four selectable AC output modes.
- PV Priority: Select this mode to maximize the use of green solar energy. Suitable for regions with relatively stable power grids.
- Utility Priority: Switches to inverter power supply only when Mains Power has failed. This functions as a backup UPS and is used in regions with suitable power grids.
- Inverter Priority: Switches to Mains Power supply only when the battery is under-voltage. Maximizes the use of DC energy and is suitable for areas with stable power grids.
- Hybrid Output and Grid Connection: In the utility bypass state, when no battery is connected or when the battery is full, the load power is supplied by the PV and the utility together if the hybrid function is enabled. Surplus PV energy is fed back to the grid if the grid connection function is enabled.

8. Troubleshooting
This section provides basic troubleshooting steps for common issues. For complex problems, contact PowMr technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter not turning on | No battery connection, low battery voltage, AC input not present, ON/OFF switch off. | Check battery connections and voltage. Ensure AC input is available. Turn ON/OFF switch to ON. |
| No AC output | Overload, short circuit, battery low, inverter fault. | Reduce load. Check for short circuits. Charge battery. Check LCD for error codes. |
| PV charging not active | Low PV voltage, PV input disconnected, MPPT controller fault. | Check PV array voltage and connections. Ensure PV voltage is above starting voltage. |
| Overload warning | Connected load exceeds inverter's capacity. | Disconnect non-essential loads. Reduce total power consumption. |
Refer to the detailed error codes and advanced troubleshooting steps in the complete product manual, typically available on the manufacturer's website.
