7.5KW Solar Inverter AC Compensation Pump

WP-7K5 Solar Pump Inverter
Manufactured by Foshan Top One Power Technology Co., Ltd.

The WP-7K5 is a 7.5 kW solar pump inverter from Foshan Top One Power Technology Co., Ltd., a manufacturer based in Foshan that has been producing renewable energy equipment since 2003. It is part of the WP Series and has been designed specifically for solar-powered water pumping, such as for agricultural irrigation, livestock watering and rural water supply, in areas where grid access is limited or unavailable.

The WP-7K5 takes DC from solar panels, converts it to three-phase AC to run pumps and adjusts pump speed based on available sunlight. The MPPT algorithm operates with 99% efficiency, continuously identifying the maximum power point, even under changing conditions such as cloud cover or temperature shifts. This ensures you get the most out of your panels throughout the day.

The WP-7K5 has a rated output of 18.5 A and supports a DC input of up to 800 V. For efficient wiring and reduced cable losses, a recommended MPPT voltage of 550 V is suggested. The output frequency is adjustable from 0 to 400 Hz, enabling you to match the pump speed to the head height and flow requirements. The unit runs on a three-phase 380 V AC output.

A notable feature is the AC compensation function, which automatically compensates for any shortfall in solar input by pulling from the grid or a generator. This ensures that the pump continues to run during cloudy periods or at night. The unit also includes water level sensing for low-water and full-tank conditions, so the pump won't run dry or waste water.

The WP-7K5 is IP65-rated for outdoor installation, so dust and rain are not an issue. Protection is provided against over-voltage, under-voltage, overload, short circuits and over-temperature. Backed by the CE and ISO9001 certifications of Foshan Top One Power Technology Co., Ltd., which has over 16 years' experience in the industry and exports products worldwide, the WP-7K5 delivers reliable performance when water depends on the sun.
