Xantrex over voltage fault error

[RolloMartins]

I am on shore power and receiving a fault light warning (Over DC Voltage). The builder of my van says he's never seen it before, but it is in the manual. It says to check cables and/or shut off alternate power charging sources. So I am thinking my 200w solar panels are bringing too much DC amps to the batteries and the Xantrex unit is showing the error from that. Should the solar unit shut off automatically? I don't see any way of shutting it off...but maybe I shouldn't even care. I get the fault and error but everything still runs (microwave/frig). Anyone seen this before?

You may want to call the manufacturer of both the solar charge controller and the inverter.
I use a morning star dou 25 amp charge controller and a magnum ms2818 .
