No matter how I change this parameter even at 13v boost I’m getting an intermittent surge of 17.5 which is coming from the charge controller.

I spoke with the people at current connected. They recommended the victron. They told me they just don’t hear anyone coming back with issues on the victron. Any reason in particular you recommend MorningStar?
