Installation of a shunt-based battery monitor

I purchased a Renogy 500A battery monitor to install in our 2020 JayFeather 24RL. After looking at the installation instructions and several websites I understand that it has to be installed on the negative side directly inline to the battery prior to anything else being wired in. The most convenient place to install the shunt and monitor would be adjacent to the factory monitoring panel next to the template sticker for a solar controller/monitoring panel. Does anyone know if the negative wire for the 4 LED battery monitor is a direct line to the battery?

The easiest and most obvious thing would be to use the wiring schematic but Jayco won't release it until my warranty expires (I called).

Any thoughts or suggestions? (I did search the forum and didn't see anything relevant.) Thanks.

Best place to install the shunt is directly on the negative side of the battery. That's where I installed my shunt. It was a pain to install the monitor wiring but it can be done.

Hi
I have the same floorplan, but 2017 23rlsw. I'm getting ready to add solar with monitor. Just wondered if you have solar and how you installed your panels and ran wiring.
Thanks

I have attached a picture of my roof with the original 2 panels installed. I routed the cables down the fridge vent, punched a hole through there into the cavity below, and then punched a hole to the underside of the rig.

I then routed the cables, enclosed in spiral wrap, to the other side of the rig and up into the cabinet right next to the battery. I have a second battery in that cabinet. That is where I installed the solar controller. Easy hook up to my second battery which has cables leading to the battery compartment next door.

My controller is bluetooth so I can monitor from my phone which is great since these cabinets are below my slide-out which makes cabinet access a bit inconvenient.

Thanks Jim! I'm looking to route the wires the same way. I like the way you put your panels in the center so you can walk your roof easier. What kind of batteries do you have? I'm looking to buy a Renogy 12v AGM 100ah. I'm reluctant to spend the money of lithium, plus I think I would hv to chg my convertor going with lithium.

I have 2 Costco 12 volt deep cycle batteries. They work OK but I am sure there are better ones available.
