Hello Grand RV community!
We just purchased a 2023 17MKE and we want to upgrade the batteries (and perhaps the solar system) to be able to boondock for at least 3 days. We live in sunny Arizona and primarily camp in the mountain areas here.
I currently have 2 group 24 lead acid batteries on the tongue, one 165 watt Furrion Solar panel, Furrion MPPT Solar Controller (FSSC30) with max charging current of 25 amps, and WF-8930 converter that has a sticker on front saying lithium compatible. I also have 12v 10cuft refrigerator. I also see #8 wire gauge from batteries to trailer (and charge controller?).
My question is this: can I get any size lithium batteries to suit our needs, even though the manual clearly states using only group 24 or 27 batteries? Why would this be a requirement? Is this due to the battery tray size on the tongue, or due to wire gauge?
If I get 200 or 300 AH lithium batteries (maybe EPOCH?), do i need to change any components or wires (i.e. different gauge)?
Thanks for any advice on this - greatly appreciated!!
