Hi all. I just bought a new to me 2022 Shamrock 233S. Been reading threads on here like crazy. We are leaving for a trip to Rocky Mountain NP in two weeks where we will be 4-5 nights without electric hookup. Currently we just have the one 190w solar panel, one 12v 85ah battery and the original solar charge controller. We do not plan to be very power hungry as we will be out most of the day hiking but want to mainly just be able to run the fridge for those 4-5 days as well as the water pump when we need it and minimal usage of lights. I tested the battery in the driveway from full charge at 8pm only running fridge and only made it about 18 hours before battery was about 20-25% (there was essentially 0 sun considering it was over night and heavy cloud cover the next day).
My question here is what upgrades might get me to last the lets say 4 days without shore power?
My first thought is upgrade to a 300ah LiFePO4 battery. If I only do this, is it a pretty much just swap out the batteries situation and changing the battery type on the solar charge controller?
Second thought is adding another solar panel. I know they are not a miracle energy source but again we are not power hungry and just looking to make it around 4 days running the fridge.
If I did just the battery upgrade or both would that get me those 4 days do you think? If I did one or both of those upgrades would I need to upgrade the solar charge controller and is that a pretty easy switch out as well ie just changing the panel in the wall?
I’m new to this and any help would be greatly appreciated!
