After returning from a week away the boat, the first thing I did before turning anything on or plugging anything in was to take a voltage reading at the battery
bank using my very good multimeter against the posts on one of the batteries. I did not remove any wires from the house bank (I am assuming this is SOP for measuring the voltage).
Then, I checked the voltage on the xantrex link 10 and it was reading .5 to .10 volts higher.
Is this common for the xantex or is there some way to calibrate the voltages?
