Can you run a well pump with a Sol-Ark 15K inverter?

Sol-Ark 15K Inverter Capacity

The Sol-Ark 15K inverter has a maximum continuous output capacity of 14.5 kW, which can support a residential well pump with a moderate to high water demand. For example, a 2 HP (1.5 kW) submersible well pump used in a typical residential application would fall within the inverter’s capacity range. When selecting a well pump for use with a Sol-Ark 15K inverter, consider the pump’s power requirements during startup and running conditions.

Compatiblity and Configuration

To ensure compatibility and optimal performance, it is essential to verify the well pump’s voltage requirements match the inverter’s output voltage. The Sol-Ark 15K inverter can produce a maximum DC output voltage of 450 VDC, and a maximum AC output voltage of 240 VAC. If the well pump requires a higher or lower voltage, additional components such as a DC-DC converter or a transformer may be necessary to match the inverter’s output to the pump’s requirements. Consult the Sol-Ark documentation and the well pump manufacturer’s specifications to ensure proper configuration and compatibility.

Well Pump Startup and Running Requirements

When sizing the well pump for use with a Sol-Ark 15K inverter, consider the pump’s startup requirements. A high-inrush current during startup can cause the inverter to momentarily go into a low-power state or even shut down if the current exceeds the inverter’s capacity. To mitigate this issue, consider using a well pump with a lower inrush current or installing a soft-start device to gradually increase the pump’s speed and reduce the inrush current. Additionally, ensure the well pump is designed for continuous operation and can handle the inverter’s fluctuating output power.
