GD100-PV series solar vfd drives are that INVT newly launches specially for solar pumping applications. Based on the original solar pump inverter products, which optimizes the usability and performance, and extends applicable voltage levels and power range of the product. The voltage level can be applied to single phase/three phase 220V, three phase 380V pumps, power range from 0.4kW to 110kW.
Comprehensive voltage level and power range Support single phase/three phase 220V, and three phase
380V solar water pump inverter, power from 0.4kW to 110KW
Easy to use Simply connect the photovoltaic panel to the inverter, no need to set any parameters, and the
PV pump can be automatically started after power-on
Multiple protection measures It has protection functions such as PV over-voltage protection, PV polarity reverse connection alarm, over-temperature automatic derating, etc., which can effectively extend the life of the product
Advanced MPPT algorithm Ensure solar power tracking efficiency can reach 99%
Boost module2.2KW and below models can be equipped with boost module to meet the needs of low voltage operation, which can reduce solar panel configuration and reduce user system cost
