What are the different pressure limits for a DualSun installation?
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.
