The S1-200 offers great flexibility to ensure maximum efficiency in every application. For this reason we designed three different pump ends: HR07, HR14 and HR23, which differ in their capacity, i.e. the amount of flow and head (or pressure) that they handle.
The following table shows the maximum flow rate and head values for each pump end:
| Pump system | S1-200 HR07 | S1-200 HR14 | S1-200 HR23 |
| Max. flow rate | 1.0 m3/h [4 US gpm] |
1.9 m3/h [8 US gpm] |
3.0 m3/h [13 US gpm] |
| Max. head | 40 m [130 ft] |
30 m [100 ft] |
17.0 m [55 ft] |
The following charts show the performance range of the S1-200 pump covered with the different pump heads HR07, HR14 and HR23.
The data includes the daily water to be pumped at different vertical heads. This data is based on using a single 205 Wp PV module at location 15N 0E.
Note that it is the same graph but with different units of measurement, the first one using the international system and the second one using the U.S. system.
