5.2 Charging Modes

The inverter offers four charging modes to optimize battery charging based on available power sources:

1. Solar Only: Charges batteries exclusively from solar power.
2. AC Priority: Prioritizes AC utility power for charging, using solar only when AC is unavailable.
3. Solar Priority: Prioritizes solar power for charging, using AC utility power only when solar is insufficient.
4. Hybrid Charging: Utilizes both solar and AC utility power for charging, balancing sources for optimal efficiency.

5.3 Output Modes

Three output modes allow for flexible power delivery to your loads:

1. Mains Priority: Prioritizes AC utility power to supply loads. The inverter switches to battery/solar power if AC utility is unavailable.
2. PV Priority: Prioritizes solar power to supply loads. The inverter switches to AC utility or battery power if solar is insufficient.
3. Inverter Output: The inverter continuously supplies power from the battery/solar, regardless of AC utility availability.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your inverter.

• Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Ensure ventilation openings are free from dust and debris. The IP65 dustproof design helps minimize internal dust accumulation.
• Connections: Annually check all electrical connections for tightness and signs of corrosion. Loose connections can lead to overheating and poor performance.
• Ventilation: Ensure the intelligent cooling fans are not obstructed and are operating correctly. The variable speed fan adjusts based on internal temperature.
• Battery Health: If using batteries, monitor their health and charge levels regularly. Follow battery manufacturer guidelines for maintenance.
