11Kw 15Hp Inverter 99.6% 380V Output High Mppt Vfd Solar Pump Inverter For Agricultural Irrigation
ZK SG600 Solar pumping system overview
The SG600 series solar pump inverter is a low voltage AC drive of 0.3 to 100KW above rating designed to operate with energy drawn from solar panel or photovoltaic cells (PV). The inverter is customized to operate in dual supply mode, so the grid connected supply is used in the absence of energy from PV cells. This drive functions with the latest in technology maximum power point tracking (MPPT) algorithm to derive maximum power from the PV cells at any instant. The inverter is specifically designed to meet the requirements of pump manufacturers and the original equipment manufacturers (OEM).

Solar arrays selection table for inverter and pumps
Connecting solar panels in series to get enough voltage input, and then calculating how much strings for getting enough power. Take a solar panels Voc38VDC, Vmp 31VDC, 265W for exampling. Please check if enough DC voltage input for system, Voc and Vmp. If the input voltage is correct, the inverter will not work properly. If the output frequency is not high, lower than 50/60Hz even in good sunlight radiation, please check if enough solar panels have been connected. The total power should be at least bigger 1.3 times than of rated power of pumps
