22 kW Solar Pump Inverter, 3-Phase, 540 to 700 V DC Input

Description

Overview

The 22 kW solar pump inverter converts DC power from your solar array into variable-frequency three-phase output, driving surface or submersible pumps up to 22 kW without mains electricity.

Maximum power point tracking (MPPT) keeps the pump working efficiently as the weather changes. It suits borehole pumps, three-phase motors, irrigation systems, livestock watering and water transfer in remote places. Built-in protection covers dry running, over-current and unstable frequency, and a sleep function cuts consumption when the pump is idle.

Key features

• 22 kW three-phase output, 45 A, 0 to 600 Hz
• DC input of 540 to 700 V, maximum open-circuit voltage 780 V
• MPPT tracking to get the most from the panels
• Sleep function that reduces consumption when idle
• Dry run, over-current and low-frequency protection
• Minimum power protection keeps the pump running in weak sun
• Air cooled with a fan, rated IP20

Where it works

This inverter suits large borehole schemes, centre-pivot and drip irrigation, livestock watering and remote water transfer on large farms in the Free State and other sites where grid supply is weak or too costly. Use it with a three-phase pump of up to 22 kW and a panel string sized to the 540 to 700 V input window, and mount it indoors or in a ventilated enclosure because it is rated IP20.
