Sargent EC155 over-voltage alarm

[LSNE]

OK so, my issue is this.
I have a Sargent EC155 control unit in my van, 150W solar system, and an Ablemail B2B charger

When my onboard fridge finishes it's cycle, it looks like the solar unit momentarily outputs over 15v which triggers the over-voltage alarm on the Sargent EC155 unit.
(I put it down to solar as it happens while driving and when engine is turned off)

Is there anyway to stop the system from generating over 15V output?

Cheers

What solar controller are you using?

I've got one inbuilt to the Ablemail, but after issues with the switching on it, I'm running with a Photonic Universe one.
