- ●Compatible with submersible pumps, surface pumps, swimming pool pumps and other pumps using three-phase/single-phase asynchronous motors.
- ●Advanced MPPT algorithm, fast response, good stability and maximum 99% MPPT efficiency.
- ●Fully automatic operation, the inverter drives the pump to work from sunrise to sunset, without manual operation after installation.
- ●Full protections including overvoltage protection, overcurrent protection and overheat automatic frequency reduction protection to extend product life effectively.
- ●Full motor protections, optional water level switch to prevent overflow and dry running.
- ●Optional power supply automatic switching function, switching to solar power or grid/diesel power supply automatically according to solar radiation conditions, which satisfies all-weather 24hours unattended water supply demand.
- ●Optional boost module for low power models (≤2.2kW) to achieve normal operation under minimum 150V input so as to solve the difficulty of solar modules configuration for low power models and reduce the overall system cost.
- ●Optional DM-BR Data Monitor, remotely monitoring system operation status with mobile APP or web pages at anytime and anywhere.
