This 48V off-grid inverter integrates high-efficiency MPPT solar charger and AC charger in one unit, supporting dual power supply of solar PV and municipal grid. When solar power is insufficient, PV and grid can jointly supply loads to guarantee uninterrupted power for home appliances. Users can freely configure power input priority between solar or grid according to local power conditions.

It supports flexible time schedule for battery charging and discharging, and works stably with or without battery. Up to 9 inverters can be connected in parallel to expand total power up to 45kW, meeting high power demand of large villas and small commercial projects. The maximum PV open circuit voltage reaches 500VDC, compatible with most mainstream solar panels on the market.

Adopting pure sine wave output waveform, the inverter effectively protects sensitive electrical equipment like air conditioners, refrigerators and computers. Optional WiFi communication module enables real-time power data monitoring via mobile APP. The whole machine meets CE, ISO, EMC, RoHS certification standards, smooth customs clearance for Pakistan, Turkey, Middle East and Southeast Asian markets. We provide full OEM private label service for global solar distributors.
