The KEWO PV1000 5.5KW 13A is the upscaled, higher-capacity model in the PV1000 series. It is specifically engineered to drive larger solar-powered submersible and surface water pumps without the need for storage batteries.

Upgraded Technical Specifications

• Power Output: 5.5 Kilowatts (5.5KW), which is equivalent to approximately 7.5 Horsepower (7.5 HP).
• Current Output: 13 Amperes (13A), providing higher torque and capacity for larger motors compared to the 4KW model.
• Input Voltage (DC/PV): Accepts a wide input range from 250V to 800V DC. The optimal MPPT voltage range is between 486V and 750V DC.
• Output Voltage (AC): Supplies 3-Phase AC voltage ranging from 380V to 460V AC.

Solar Array Configuration Guide

To run a 5.5KW pump safely and efficiently, consider the following manufacturer recommendations:

1. Total Solar Array Capacity: It is highly recommended to oversize the solar array by 1.3 to 1.5 times the pump's power. For a 5.5KW load, you should install a minimum total of 7.15 kW to 8.25 kW of solar panels.
2. String Voltage Configuration: Connect your solar panels in a series string so that the total Open Circuit Voltage (\(V_{oc}\)) reaches between 620V and 750V DC. This ensures early-morning startup and reliable torque in low-light conditions.

This unit maintains the full suite of smart features including 99%+ MPPT efficiency, dry-run protection to safeguard the pump when the well is empty, and hybrid capability allowing alternative AC input from the grid or a generator.
