While dad and I were on the boat, I made a “small” change to one of the Xantrex inverter/charger settings. The ‘Power Share’ setting in the Xantrex menu was set at 15 amps. Not reading the manual at the time, I changed the setting to 30 amps; after all, Lollipop has a 1400 plus amp hour battery bank. Whoops! I was thinking 12 volt DC output when it is 30 amps @ 120 volts or 3600 watts / 12 volts = 300 amps DC. Fortunately, the battery charger output is only a mere 200 amps. This was not a problem until the boat was off shore-power and generator power for a while and was using the battery bank. When we hooked back to shore-power, the charger started pushing all 200 amps into the battery bank, heating up the batteries and leaving no power to run anything on that leg of the breaker panel. Luckily for me, the charger is equipped with a temperature probe, and when the battery bank reached 135 degrees F, it backed off on the charge rate. “Lessons learned!”
Unfortunately, this required a trip back to the boat to correct, but that is Deb’s story.
