Why do I need a 3 bar valve if the maximal pressure in the module is 1.2 bar?

The maximum operating pressure of the hybrid module is 1.2 bar dynamically. For installations where the difference in height between the machine room and the panels is less than 15 meters: the solar thermal stations include 6 bar safety valves, which is not enough to protect the hybrid panel.

It is therefore necessary to install a safety valve with a set pressure of 3 bar. For installations where the difference in height between the machine room and the panels is greater than 10 meters, a solar thermal station equipped with a 6 bar safety valve is suitable.
