Solution?! UPS 1s Interrupt EP500Pro

Hey everyone,

i’ve recently catch a topic here, where someone mentioned a 1s AC Interrupt while using UPS mode.

Cant find that post anymore, but it was mentioned, that the issue cant be reproducted. I had a similar issue yesterday with my EP500Pro, which may could the source of this.

For save some of the energy, when my B210 is full from the balcony system, i do have smartplug which turn on, when there is a certain grid export reached.

My EP500Pro was in Standard UPS mode, AC charging is set to 1A. Every few minutes, the pro stops charging for about 1s and continue after that just fine. No error. Everytime this happend, you hear the realy clicking. The smartplug is on, all the time.

I start to search, what this problem could trigger.

Didnt find a final conclusion, but when i switch to custom UPS, still with 1A and extend it later to 2A. Its just gone.

Maybe that help you guys to find and fix the problem.

greetings
Erik
