PV & Grid Jointly Supply Loads When Solar Power Is Insufficient
Dual power complementary design; grid/generator automatically supplements power when PV generation is inadequate to guarantee continuous power supply for household loads.
Flexible Time Schedule for Inverter Charging & Discharging
1. Customize charging and discharging time periods as needed to realize intelligent energy management and maximize solar self-consumption rate.
Support Up To 9 Units Parallel, Max 45KW Total Expandable Power
2. Parallel connection of 9 inverters enables total system power up to 45kW, meet the power demand of large villas, small farms and multi-family off-grid systems.
Max 500VDC PV Input Voltage, High MPPT Solar Charging Capacity
3. 120V-450V wide MPPT operating window, max PV open circuit voltage 500V, match high-power solar modules and reduce wiring loss.
Configurable Grid or Solar Input Priority
4. Freely switch power supply priority between solar PV and auxiliary AC power according to local sunshine and electricity price conditions to cut energy cost.
Dual Working Modes: Work With Or Without Battery
5. Two operation modes available, applicable to users with battery storage and users who only need real-time solar power without energy storage.
High Surge Power & Pure Sine Wave Output
6. Double surge power can easily start heavy loads like air conditioners and water pumps; pure sine wave output protects sensitive electronic equipment from damage.
7. Lightweight Compact Body, Easy Indoor Installation
Ultra-light weight (9.2kg/9.8kg) and small size, save installation space, simple wall-mounted operation for installers.
1. Small Rural Off-Grid Household Power Supply (Africa, Remote Middle East)
Independent solar power system for rural villages without stable municipal grid, supply daily power for lighting, fans, TV and small home appliances.
2. Household Emergency Backup Power (Turkey, Power-Unstable European Regions)
Quick switching backup power during grid blackouts, maintain normal operation of refrigerators, lighting and essential loads.
3. Small Cabins, Camping Sites & Tiny Homes
Lightweight solar power solution for mountain cabins, RV camps and temporary tiny houses, support battery-free real-time power supply.
4. Small Farm & Greenhouse Standalone Power System
Self-sustaining power for agricultural greenhouses, irrigation pumps and farm lighting, optional battery-free mode to save storage cost.
5. Old Small Off-Grid Solar System Capacity Expansion
9-units parallel design supports capacity upgrade of existing small solar systems without full set replacement.
7. Low-Budget Solar Power System Without Battery
Battery-free operation mode for users who only need daytime real-time solar power, reduce initial investment of energy storage equipment.
