What are the different pressure limits for a Dualsun installation?

Edited

The inflation pressure of the expansion tank (which is not always mandatory :

Is it necessary to have an expansion tank with a Dualsun SPRING installation? ) and the maximum pressure of the solar circuit at panel-level are given in the following table:

 

Heigth between the panels and the solar station [m]

0

2

4

6

8

10

12

14

Service pressure [bar]

1,5

1,7

1,9

2,1

2,3

2,5

2,7

2,9

 

This tab follow the rule Pmax =1,5 + H/10

 

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