80V throughput when SSR is off

Hi guys, I have a problem with the 3 phase SSR from the brewpi shop.
When the SSR is off there are still 80 Volts on the output side. Does anybody have the same issue and possibly a solution?

Can I guess that you did not have a heating element connected? The SSR has a very high resistance when turned off, but if you connect nothing on the other side, the really tiny current that can pass through the SSR will give a voltage on your multimeter, which also has a very high input resistance. Once you connect your element (very low resistance), you will measure zero voltage at the output in the off state.

Yep, you’re right. I will test it with the connected heating element. Thanks for the quick help!
