Threw dull care away and decided to wire shunt for battery. I was able, using table top clips to mount the controller vertically. I first mounted it on site scrap walnut and rabbeted the edges so the clip would fit. Mounted the clips the box and the controller on a board slides into the clips, snug on the wall of the battery box. The shunt wires go from battery box on top of the water tank to the counter cabinet to the small shunt monitor....seems to be spot on to the Victron app. I have to admit I have learned a lot from the patient folks willing to help out on WTW. There is NO WAY I would have attempted this project without their guidance. Everything is installed. I turned on the fridge and fan to see the load. It really is cool to see what each appliance draws. And to see how the solar panel is doing. I will now plug in the portable 100 (roof is 160) and see how that adds to the picture.
Caring for this LiFePo4 battery will need to be investigated. I know, when storing the camper in the barn for the long cold winter I won't have to plug in the battery. just draw down the voltage and let it sit at 12V. I also need to find out how the FWC shore power plug in will affect the lithium battery. I assume it will work.
I am curious where you got the 12V level for storing your LifeP04?
During my research I have understood that 50% is a good storage level for LifeP04.
Now 12V is 50% for an AGM but not a Lithium. Lithium holds it's voltage through the usage cycle.
When I received my Renogy 50AH LifeP04 I checked it's voltage. It was at 13.1.
I charged it for 4 hours at 5-6 AH's before it stopped taking juice. It had gulped down about 25AH's or 50%.
You might want to check on that voltage number for storage.
I am also new to this so claim no expertise just lots of study.....
Hope this is helpful:)
