Chris,
I have a 12vdc sunfrost fridge and a few 12v receptacles left over from
the 12v days and I did the same as your customer with 2L16’s and a few
panels and backed it up with an Iota charger plugged into an AC outlet
powered by my 48v Outback inverter. Then I discontinued the dedicated Pv
panels when remodeling the house and eventually got rid of the batteries.
Just the Iota to the DC circuit works great!
Happy New Year
