Charge Modes:

1. Photovoltaic Priority: Solar charging is prioritized. Mains power is used only when photovoltaic power is insufficient or unavailable.
2. Mains Supply Priority: Mains supply is the primary charging source. Solar power is used as a backup.
3. Mixed Charge: Utilizes both solar and mains power for charging, prioritizing solar when available and supplementing with mains as needed.
4. Only Solar: Exclusively uses solar energy for charging, maximizing renewable energy utilization.

Output Modes:

1. PV Priority: Prioritizes power from solar panels to supply the load. Switches to utility or battery if PV power is insufficient.
2. Utility Priority: Prioritizes power from the utility grid. Switches to battery or PV only when the utility grid is unavailable.
3. Inverter Priority: Prioritizes power from the battery bank. Switches to utility or PV when the battery voltage is low.
4. Mixed Functions Mode: When the battery is not available or fully charged, the load is supplied by a combination of PV and commercial power, with PV providing maximum output.

Monitoring and Control:

The inverter can be monitored and controlled via the SmartESS App. An optional Wi-Fi/GPRS data acquisition module (purchased separately) is required for this functionality.

Monitor and control your inverter settings and performance using the SmartESS App. The Wi-Fi/GPRS data acquisition module needs to be purchased separately.

6. Maintenance

To ensure the longevity and optimal performance of your PowMr Hybrid Solar Inverter, regular maintenance is recommended.

Cooling System:

The inverter features an intelligent variable speed fan system that adjusts its rotation speed based on ambient temperature and environmental conditions. Ensure that the cooling vents are not obstructed to allow for proper airflow.
