Epever 5415AN PV overvoltage

[Olker]

Hello Forums,
i own a Tracer5415AN with maximum PV open circuit Voltage of 150V.
My Panels open cuircuit voltage is 115V - also shown in the Epever station Monitor software.
But the problems is that the Tracer is blinking fast green - "PV overvoltage".

What could be the Problem..?

Best regards

Olker

Put a DMM on the input leads and see what you're getting.
The assumption is your panels are wired in series - how many of what rating?

For a system reset, be sure to power off the PV array first, then battery connection to the SCC - start them in reverse, battery first, then PV.

Has this setup worked correctly for some time? Or is this a new installation?

I have a XTRA controller and it's a little funky from time to time, but no errors.

The DMM shows the identical voltage as the Epever.
The wiring in Series is with two Panels with Voc 66,6 open circuit and Vpm 53 on load.
It is a new installation.

Is it charging? Or shut down?
Mine flashes green when it's charging.

It is not charging. I will try this night to leave it on its own without Battery connected.
So PV voltage can increase in the morning. See what is happening.

Controller needs to be powered up before PV current is connected.
