When solar output cannot meet load demand, solar power and municipal grid supply household appliances simultaneously, delivering consistent, uninterrupted electricity for daily use.

2. Customizable Battery Charge & Discharge Timers

Freely program charging and discharging periods to take advantage of off-peak utility rates, effectively cutting long-term household electricity expenses.

3. Expandable Parallel Design — Up to 9 Units, Max 45kW Total Output

Connect up to 9 inverters in parallel to scale the whole system to 45kW, fully catering to power needs of large villas and multi-family residential buildings.

4. 500VDC Max PV Open Circuit Voltage, Wide 120–450V MPPT Operating Range

Compatible with most mainstream high-wattage solar panels. Offers flexible rooftop array layout and maximizes overall solar harvesting efficiency.

5. Switchable Input Priority Modes

Two customizable operation logics: Solar First or Grid First, to fit diverse family energy consumption preferences.

6. Unique Dual Operation Mode: Run With or Without Batteries

Exclusive circuit architecture allows the inverter to operate stably even without battery storage, slashing upfront solar system investment costs significantly.

7. Built-In AC Charger, Universal for 48V Batteries

Works seamlessly with LiFePO4 lithium and lead-acid batteries. The integrated high-speed AC charger quickly refills batteries via grid power.

8. Pure Sine Wave Output + Auto 50/60Hz Frequency Detection

Clean pure sine wave power safeguards delicate household electronics against damage. Automatic frequency recognition supports deployment across global markets.

Application Scenarios
