Solar Motor Drive
Designed for 3-phase AC motors, the HAMAK PVMT Series features a proprietary MPPT algorithm that converts DC power from solar panels directly into AC power. No battery storage is required. It efficiently drives water pumps, aerators, and industrial ventilators, making it the ideal partner for agriculture, aquaculture, and industrial energy savings.
Feature Highlights
Battery-free architecture
The integrated MPPT and proprietary MPP program adjust output according to solar irradiance, enabling operation from morning to late afternoon without any batteries, reducing CAPEX and eliminating battery replacement costs.
Reuse existing motors and machinery
With standard three-phase AC output (220Vac or 380/400/415/440Vac), HA-PVMT drives existing pumps, aerators, blowers, and fans without replacing motors or mechanical systems, minimizing retrofit effort.
High efficiency with full protection
With >98% full-load efficiency and comprehensive protection (PV reverse polarity, over-temperature, over-current, earth leakage, etc.), plus forced-fan cooling and an LCD for real-time monitoring, the system runs safely and reliably for years.
Smart Automation
Equipped with two sets of sensor interfaces (AVI/ACI) for connecting water level sensors or dissolved oxygen sensors, enabling fully automatic start/stop control without manual supervision.
Customizable Start Power
End-users can configure the drive's starting power based on different motor types to ensure the submersible motor delivers the minimum required pumping lift to overcome the TDH, preventing potential motor burn-out.

Agriculture: Water pumps, Livestock & Greenhouse ventilators
Aquaculture: Feed-in pumps, Paddle wheel aerators, Recirculating pumps
