Key Features
Dual Power Joint Supply & Adjustable Input Priority
PV and grid/generator can jointly power loads when solar energy is insufficient; users can configure PV first or grid first working mode freely.
Flexible Charge & Discharge Time Schedule
Customize charging and discharging time periods according to local electricity price or sunshine condition to optimize energy utilization.
Expandable Parallel Connection
Support maximum 9 inverters connected in parallel, expand total system capacity up to 45kW to meet large off-grid load demands.
High Voltage MPPT Solar Charger
Max PV open circuit voltage up to 500VDC, max PV array power reaches 6000W for 5kW model, wide MPPT range 120-450VDC to improve solar charging efficiency.
Unique Work With / Without Battery Function
Two operation modes available: work with 48V LiFePO4/lead-acid battery for energy storage, or run without battery for direct PV-to-load power supply to cut equipment cost.
Multi-Source AC Input Compatibility
