22KW Solar Pump System Inverter

SPC-22K0 solar pump inverter – manufactured by Foshan Top One Power Technology Co., Ltd.
The SPC-22K0 is a 22 kW solar pump inverter manufactured by Foshan Top One Power Technology Co., Ltd., a company based in Foshan, Guangdong, which has specialised in the production of renewable energy equipment since 2003. It is part of the SPC series and has been designed specifically for solar-powered water pumping, including agricultural irrigation, livestock watering, rural water supply and remote off-grid sites where grid power is not an option.

The SPC-22K0 differs from standard solar inverters in that it is designed for a specific purpose. A standard solar inverter converts DC to AC for homes or the grid. The SPC-22K0, however, is tuned for pumps. It handles the startup surge, adjusts speed based on available sunlight and keeps water moving even when clouds roll in. It's a tool for moving water, not just generating electricity.

The SPC-22K0 has an output of 22 kW with a rated current of 45 A - enough to power medium to large pumps for farmland irrigation or community water systems. The MPPT tracking achieves 99% efficiency, meaning it utilises almost all of the energy produced by your solar panels for pumping water. The DC input range is wide (250V to 800V), so there is flexibility in panel configuration. The output frequency ranges from 0 to 400 Hz, enabling precise adjustment of pump speed for different head heights and flow requirements.

The unit runs on a three-phase 380 V AC output. It has an AC compensation feature that blends solar and grid power automatically. If the sun provides 80% of the required power, for example, the inverter will pull the remaining 20% from the AC input to ensure the pump runs at full capacity. This is a useful feature for hybrid systems where downtime is not an option.

Cooling is handled by an intelligent, speed-regulated fan that ramps up when necessary and slows down when it isn't. Protection is provided against over-voltage, under-voltage, overload and over-temperature. Backed by the CE and ISO9001 certifications of Foshan Top One Power Technology Co., Ltd., the SPC-22K0 delivers.
