Solar Power Control System
Type “SPCS 4 (5,5) – 400”

The Solar Power Control System” – SPCS 4 (5.5) – 400 drives are designed to be built in autonomous solar pump installations. The device is intended for direct supply the pump’s three phase AC induction motor.

The 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 and could use up to two sets of liquid level sensors (electrodes).
