Frequently asked questions

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

Maximum head ratings range from 26–255 m across 38 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 4DFSW (AC/DC) series deliver?

Maximum flow ratings range from 4.8–30 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 4DFSW (AC/DC) series?

The catalog lists these voltage options: 80-430V, 110V, 72V V. Match the selected model and controller specifications when sizing the solar array.
