Page 12: Introduction
POWER ELECTRONICS INTRODUCTION Power Electronics has a strong commitment to reduce the levelized cost of water (LCoW) by offering upgraded energy saving solutions. Synergies between our Industrial and Solar Divisions have come together in the SD700 SOLAR POWER – SD700SP. This unique 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). -

PV panels connected in series. The number of strings in parallel will be determined according to the pump power. Power Electronics has developed a system, which is able to use all DC energy available and it takes only power from the AC supply when it is needed. This system connects/disconnects the AC input to the mains therefore avoids the need of having a "stand by"... -
