Batteries Overcharging Badly

[pgchin]

I'm glad you will be getting to go on your trip and did not miss out!!!! The diodes as well as the regulator being correctly wired info in this thread would be helpful to them and you......take it with you on your trip as well if you have limited internet access in case you have issues on the trip.
Don't worry about the batteries........run them for an hour or two, then when you pull into a rest area for a break, open up the battery compartment doors and feel the sides of the batteries for "heat".......they should be at ambient temp all the time. An overcharged battery will run hotter than ambient temp. Also I think I read you were running flooded cells, take a flash light and check for wetness around the cell caps of all batteries...... overcharging flooded cells will spew acid and the tops of the batteries around the cell caps will be "wet"....... Most of all ENJOY your trip........we ALL run with issues and a punch list............ nature of the beast!
PS FWIW the "default" settings for the inverters is flooded cells so you should be OK............when the panels/ inverters loose power like replacing batteries, disconnects, etc. the inverter settings revert to the default settings.....
