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

Description

Overview

This 11 kW solar pump inverter converts DC power from solar panels into three-phase AC to drive an 11 kW pump motor, with no grid connection needed. It uses MPPT (maximum power point tracking) to draw the most from the panels as the sun changes, and it outputs up to 25 A over a 0 to 600 Hz range. It works with surface and submersible pumps, so it suits borehole, irrigation, livestock watering and water transfer jobs on farms and remote sites.

Key features

• 11 kW, 3-phase output, 25 A output current
• Input voltage 540 to 700 V DC, maximum open-circuit voltage (Voc) 780 V
• MPPT to optimise power from the panels in changing weather
• Sleep function to cut energy use when idle
• Dry-run protection that detects low water levels
• Over-current and low-frequency protection for the motor
• Minimum power protection to keep the pump running when sun is reduced
• Air cooled with a fan, 0 to 600 Hz frequency range

Where it works

Use it on irrigation and livestock water systems in Limpopo and the Free State, on remote boreholes in the Northern Cape and Karoo, and for community water supply where grid power is poor or load-shedding hurts. Keep the open-circuit voltage of the panel string below 780 V on cold mornings, and install the inverter in a dry, dust-free cabinet, as it is rated IP20. Larger pumps need the 15 kW inverter or the 18.5 kW inverter. Browse more solar pumps.
