Adopting the proposed dynamic VI maximum power point tracking (MPPT) control method; Fast
response speed and stable operation; Better than the conventional methods which may lead to the
problems including poor tracking performance, unstable operation or even damaging water hammer
effects when the irradiation on the array change rapidly.
Digital control with full automatic running, data storage and complete protective functions (overload, over
voltage, under voltage, over heat, reverse polarity, thunder, over flow and dry running).
The main circuit adopts intelligent power module (IPM), with high reliability and high efficiency 98%.
Unique design of aluminum alloy with good cooling and shielding, LCD display (43*29mm) and keys, easy operation, good view through LCD when setting parameter, feel comfortable.
Protection degree IP41, working temperature: -10c+50c
Inverter connects to city power when there is no sunshine to keep system pumping water is available
(optional).
Low voltage drive device is our patent right product, can be used in small solar pumping system to save
the quantity of solar panels.
