Solar Power Control System / Booster

The Solar Power Control System – Booster” – SPCS-B drives are designed to be built in autonomous solar pump installations. The SPCS-B device is intended for direct feeding a three phase AC induction pump motors. SPCS-B drive integrates a step-up DC-DC converter for optimizing the installed PV panels and reducing the overall system cost.

The SPCS-B drive is for outdoor installation. It implements user friendly “plug & play” design for quick installation and fan less design. After installation the drive could work in automatic mode and there is no need of additional adjustments.

The drive is compatible and easy to operate with different types of water pumps.

The system implements water level control functionality through one set of liquid level sensors (electrodes).
