PV Module Selection:
When selecting proper PV modules, consider the following parameters:
- Open circuit Voltage (Voc) of PV modules must not exceed the maximum PV array open circuit voltage of the inverter (500VDC).
- Open circuit Voltage (Voc) of PV modules should be higher than the minimum battery voltage.
| Inverter Model | Max. PV Array Open Circuit Voltage | PV Array MPPT Voltage Range |
|---|---|---|
| 1.5KVA / 3.5KVA / 5.5KVA | 500VDC | 120VDC~450VDC |
Parallel Operation:
The PowMr 5.5KW 48V Hybrid Solar Inverter supports parallel operation for increased capacity, up to 9 units. The parallel kit is built-in for models supporting this feature.
Single Phase Parallel Operation:
Three-Phase Parallel Operation:
WARNING: Do not connect the current sharing cable between inverters that are in different phases. Otherwise, it may damage the inverters.
5. Operation
The inverter features a comprehensive LCD display and user-friendly buttons for configuration and monitoring. Refer to the detailed instructions in the included user manual for specific menu navigation and setting adjustments.
Configurable Settings:
- Battery Charging Current: Adjust the charging current to optimize battery life and performance based on your battery type and capacity.
- AC/Solar Charger Priority: Set the preferred power source for charging your batteries (e.g., prioritize solar power over AC utility).
- Input Voltage Range: Configure the acceptable input voltage range for different applications (e.g., UPS mode for sensitive electronics or appliance mode for wider tolerance).
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your PowMr Hybrid Solar Inverter.
- Cleaning: Keep the inverter's exterior clean and free from dust. Use a dry cloth for cleaning. Ensure ventilation openings are not blocked.
- Connections: Periodically check all electrical connections (PV, battery, AC input/output) for tightness and signs of corrosion.
- Environment: Ensure the operating environment remains within the specified temperature and humidity ranges.
- Battery Health: Monitor your battery bank's health and charge levels, especially if using lead-acid batteries, to ensure efficient operation and prevent damage to the inverter.
7. Troubleshooting
