ScottG - call them and they will tell you how to adjust it on the phone. There’s a small pot to adjust it. Mine read high when new and would often shut off power in the middle of the night when campground voltages went higher. I called/adjusted ours in May 2017. I emailed them first and they told me to have the top off and a good voltmeter when I called. Been fine ever since. Hopefully, that still works.
