INVT GD100-PV 18.5kW MPPT Three Phase Solar Pump Inverter

INVT GD100-PV 18.5kW is a professional MPPT solar pump inverter designed for photovoltaic water pumping systems used in agriculture, irrigation, tube wells and water supply applications. The GD100-018G-4-PV provides 18.5kW rated motor output and is designed for three-phase 380V pump motors. It features 47A rated input current, 38A rated output current and supports up to 50A maximum DC input current. Its advanced built-in MPPT algorithm continuously tracks the maximum available solar power, achieving more than 99% MPPT efficiency for efficient pumping under changing sunlight conditions. For the 380V class, the inverter supports up to 800V maximum DC input voltage, 300V startup voltage and 250V minimum working voltage. The recommended PV operating voltage range is 300V to 750V, with approximately 550V recommended MPP voltage. The GD100-PV platform supports both solar PV DC input and three-phase AC grid input, allowing hybrid operation and reliable pumping when solar energy alone is insufficient. Integrated solar pump control and protection functions make it suitable for agricultural irrigation, groundwater pumping, tube wells, livestock water supply and other continuous water pumping applications.
