CyberPower 3.7kW Solar Pump Controller CPSPI3700EVF380

Solar-Powered Water Pumping — Zero Fuel Cost

The CPSPI3700EVF380 converts solar energy directly into three-phase AC power to drive agricultural and domestic water pumps. No batteries required — the controller operates the pump whenever sufficient solar energy is available, automatically adjusting pump speed to match available solar power.

3.7kW / 5HP Motor Drive

Powers standard three-phase water pumps up to 3.7kW (5 horsepower) with surge handling up to 8250W for motor startup. This capacity serves most agricultural submersible pumps, surface pumps, and irrigation systems used in small to medium farming operations.

Intelligent Water Management

Built-in water level detection automatically controls pump operation based on water levels in towers, tanks, or wells. Dry-run protection prevents pump damage when water source is depleted — a critical feature for borehole applications where running dry can destroy expensive submersible pumps.

Wide Solar Input Range

Accepts 350-750V DC solar input with MPPT tracking up to 98% efficiency. The wide voltage range accommodates various panel string configurations and maintains pump operation even during partial cloud cover when panel voltage drops.

Applications

Agricultural irrigation, livestock watering, village water supply, fish farming, and remote water distribution. Eliminates diesel fuel costs entirely — the water pump runs on free solar energy for 15+ years.
