Well since you ask,
I have already installed a 460 AH Vatrer lithium battery since it was on sale and my old led acid batteries were 5 years old. The battery was $1100 and 4 agm batteries were going to be close to that.
I also plan to install 600 watts of solar, 6-100 watt eco-worthy 12 v panels that were also on sale, I don't remember the exact price, but just under $300.00. Of course then I needed mounting brackets so just over $300.00.
The two wires from Beaver are heavy enough to use,10ga, to hook up to a charge controller. I bought a Victron MPPT 100/50 charge controller, also on sale, for about $125.00. I also have some wiring combiners left over for a different project. I will need a few other pieces, but less than $100.00.
I plan to clean, seal, and then re-coat my roof before the install, so at least spring if not summer.
With the above set-up I believe I will be able to run my 12 volt refrigerator pretty much indefinitely unless the panels are covered with snow. This should also keep all the batteries charged.
This is still a plan in progress. I did install a BIM to protect the alternator, and currently use a trickle charger to keep the chassis batteries charged while the original freedom 15 inverter charges the house battery just fine. I did have to reconfigure the dip switches, but with the batteries BMS it will charge up to 100% when it decides it is time to charge the battery.
I am far form an expert so just take this as what I am doing. There are others here that are much more informed than me so ask questions before you plan yours. I pieced together the on sale version.
