Please note that the input and output voltage must be within the voltage range of the product. Please note that the output port of the inverter must be connected to the household power grid socket (civil single- phase power grid) through an AC power line so that the product can work normally! Please note that the PV input power is recommended to be greater than 20% of the rated power of the product. Please note that the Vmp of the solar panel must be within the MPPT range to ensure the best MPPT maximum power output. We recommend using 36V photovoltaic panels (VOC voltage between 26-50V) or 36V batteries as input power to obtain better output power. Please note that the DC terminal must be tightened, otherwise, the product may be damaged. Please note that the grid tie inverter cannot be used as off grid/stand alone solar system. The output needs to be connected to the grid power. And it can not supply power directly to the AC loads. Please read the operating manual completely before use. And pay particular attention to the safety instructions included. High-Efficiency MPPT TechnologyEquipped with advanced Maximum Power Point Tracking (MPPT) to maximize solar energy harvest and ensure stable output. Clear LCD Performance DisplayIntegrated LCD screen provides real-time monitoring of voltage, current, power, and frequency, making operation transparent and easy to manage. Robust Safety FeaturesIncludes over-temperature, under/over-voltage, overload, short circuit, and electrical isolation protections to ensure safe and reliable inverter operation.
