Trial Time Setting Function Solar Water Pump Controller With 99% Efficient MPPT
1. The advantages of solar pump inverters
1) Operates without grid directly from photovoltaic (PV) cells to save more energy and provide enough power
for your solar water system
2) Automatic start and stop with solar radiation to make sure that the solar pump inverter can work in high efficiency
when the solar power is enough for the machine
3) Built-in maximum power point tracking(MPPT), more than 99% MPPT to provide you stable flow power
4) Easy installation and set-up for serial production, more compact product size for better installation and save more
space for delivering
5) Compatible with all pump types, which can be applied in many industries for different motors
