What are the different pressure limits for a DualSun installation?

The inflation pressure of the expansion tank and the maximum pressure of the solar circuit at panel-level are given in the following table:

 

Height difference between
panels and expansion tank

2m

4m

6m

8m

10m

12m

14m

Pre-inflation expansion tank pressure

0.9 bar

1.1 bar

1.3 bar

1.5 bar

1.7 bar

1.9 bar

2.1 bar

Maximum solar circuit pressure

1.4 bar

1.6 bar

1.8 bar

2.0 bar

2.2 bar

2.4 bar

2.6 bar

 

These pressures must not be exceeded in order for the warranty to remain valid.
