Battery Isolator
Posted a question two weeks ago about the possibility of running an inverter off of the battery isolator. Not such a good idea. I'll go to solar to keep my batteries topped off while I'm driving. Wh...

I'm not so sure I like this solution. Is there a better way of getting the voltage down?
I'm an EE. If you're measuring the no-load voltage coming out of a charge controller when not hooked to a battery, I wouldn't be afraid of 15.5V. It simply doesn't mean much as no load.
What matters is how many amps are being pushed when it is connected and how high it'll allow the battery to charge.
Generally, connected, I wouldn't want to see a charge voltage much higher than 14.7v.
You may be chasing shadows here... It much more important for your charge source to be able to regulate-down when the battery gets full than it is to hit or miss any peak no-load voltage.
