mareng16 Posted June 4 Share Posted June 4 Hi everyone ... I'm new in this forum, but I use Shelly since longer times. My question now: I want to use the above Shelly for simultaniously output AND input power. I have 3 consumers ( 2 for a short time and very less current, and 1 with up to 70 W for more ore less continous time). And now I think about using the free channel to attach my "Balkonkraftwerk" (balcony solar) with up to 600 W. I want to measure the pump (70 W) and the output of the solar panel system at the same time. Is there a risk for the Shelly Pro 4 PM ?? Can I do this ? I don't want to kill the new device. Thanks in advance. mareng16 Quote Link to comment Share on other sites More sharing options...
Administrators Olsche Posted June 4 Administrators Share Posted June 4 It is possible without any problems, I also use something similar with similar consumers and a balcony power plant. Please note, however, that it is probably necessary to use an RC snubber with the pump https://kb.shelly.cloud/knowledge-base/rc-snubber Quote Link to comment Share on other sites More sharing options...
