Warning: Overload L1 on Ve.bus

Good day all.

I've been getting the above mentioned warning for a few weeks now. My installation went live 24 November 2022.

Every time the grid fails (loadshedding in South Africa), I get this warning and then it clears. Warning only, no alarm.

My installer installed an over under voltage protection relay after my main incoming breaker.

My grid code was changed as well as AC in low was changed to 210V

Still I get the Overload L1 warning when the grid fail. Not every time, but occasional. Few times a week.

Looks like my system is picking up a very low voltage from the grid just as the grid drops out (saw 61.4V today on the VRM graphs)

No idea how to or where to now from here?

What else can we try or look at?

Would really appreciate if anyone can assist in this matter.

It is not uncommon and can have different causes, one of which is a poor grid.

My supply does the same from time to time, I just disabled that warning so it didn't bug me once it became apparent it was inherent in the environment and wasn't causing problems.

6 month view (happens every couple of days or so).
