Quick update. We have had these installed for a little over 2 months, now, and couldn't be happier. Overnight use takes the bank down to about 88% and if it's sunny we are in float by noon. We have a TV running for a couple hours at night, laptop, 12V Furrion 'fridge, 5 cu ft chest freezer, CPAP machine, and assorted wall-warts and battery chargers.
My wife is so happy with them she told me to order another! Should be here in a couple of weeks so we will have 4 for 800 AH.
