Frequently asked questions

What is the maximum head of the 4HJSS series?

Maximum head ratings range from 70–112 m across 3 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 4HJSS series deliver?

Maximum flow ratings range from 2.6–3.7 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 4HJSS series?

The catalog lists these voltage options: 48V, 72V V. Match the selected model and controller specifications when sizing the solar array.
