Introduction SolarTech PB – G3 Series Pump Drives offer an advanced 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. Multipump linkage Capability PB – G3 Series supports multi-pump linkage for large-flow, high-lift applications, enhancing power efficiency and reducing the required PV module configuration. Integrated Hybrid power function SolarTech PB – G3 Series supports PV/AC complementary input with a solar priority function, enabling 24-hour operation. The system maximizes solar energy use while automatically limiting AC power consumption to achieve significant energy savings. Flexibility and Robustness Built with high-quality components, the system offers a wide input voltage range, integrated boost circuits for low-power models, and flexible solar panel configuration options.
