Panel-mount variable-speed drive SD700SP Series

The SD700SP Series is a solar pumping manufactured by Power Electronics company. The product takes advantage of the outstanding features of the SD700 variable speed drive to power pumping systems from either the solar PV panels (off-grid) or simultaneously from the PV panels and grid supply (PV solar assisted). The unit is factory approved solution comprising a customized SD700 VSD, DC protections, disconnection and filtering, and an upgraded firmware, which leads to easy installation and commissioning. The AC input voltage determines the SD700SP DC bus voltage and therefore the required DC voltage of the strings..The maximum energy produced at the fixed DC voltage depends on the number of PV panels connected in series.
