Hi BigHatnohorse,

The computer boards in RV's dc systems are safe up to 15.4 volts.

I have the Blue Sky 3024 di. I've never had a problem with over voltage. the unit is set to 15.2 volts for equalization.

Time2roll the Blue Sky has extremely limited adjustment via dip switches. They sell a separate "calibrator" called an IPNPRO remote for fine tuning. It, unfortunately, costs nearly as much as the charge controller itself. Your Morningstar is a much better buy.

There is a dip switch setting to turn equalization off.
