Monitor Panel and Converter

[Koroks]

Recently encountered an electrical loss during a thunderstorm. Power went off for roughly 3 - 5 seconds. I am connected to a 50A power pole, I do not have a surge protector in-line.

Since this incident, my monitor panel will only display maximum values on all tanks/battery, even tho some are duds like the Blk2. All other switches for slides, water heater, interior lights etc. are functioning. Would this likely be a shorted monitor board?

I have also started recording the voltage at the DC distribution and have noticed a continued decline in voltage with what I assume is no charge from the converter. Is there a good way to test or reset the converter, other than monitor battery voltage?

This is a 2022 Crossroads Volante 32FB, any help appreciated I'll keep scratching my head looking for solutions.
