Introduction

SolarTech PK Series Pump Drives offer a cost-effective solution to convert existing AC pumps into solar pumps without replacement. They use solar panel power, converting it to AC to run pumps at variable speeds based on sunlight availability.

General Description

Solar power varies throughout the day. By running the pump at variable speed, load power is matched to available solar power. The built-in MPPT extracts maximum energy, while a DC-DC converter adjusts voltage for AC conversion. Output frequency adapts to available power, controlling pump speed and flow accordingly.

Compatible with range of pumps

Compatible with submersible, surface, swimming pool, and other pumps using single-phase or three-phase asynchronous motors.

Fast MPPT

Leading MPPT algorithm, fast response, good stability and maximum 99% MPPT efficiency.

Automatic speed adjustment and soft start

With fast response and stable performance, the system offers fully automatic operation, adjustable frequency range, soft start, full motor protection, and optional water level switch for overflow and dry-run protection.
