Frequently asked questions

What is the maximum head of the 4HJSC (AC/DC) series?

Maximum head ratings range from 50–203 m across 28 models. Select a model using its performance curve at your required total dynamic head, including elevation, pressure and pipe friction losses.

How much water can the 4HJSC (AC/DC) series deliver?

Maximum flow ratings range from 3.5–30 m³/h. Actual flow depends on operating head and available power. Maximum head and maximum flow are separate ratings; check the performance curve for your operating point.

What voltage options are available for the 4HJSC (AC/DC) series?

The catalog lists these voltage options: AC380/DC520V V. Match the selected model and controller specifications when sizing the solar array.
