Paradigm 310RL Battery / Inverter Install -- Location & Charging

[Dkamp]

We recently purchased a 2025 310RL and I'm in the process of expanding batteries (24v system) and adding inverters to allow more off grid adventures. As I'm laying out the plans, I wanted to get some feedback on a couple questions I'm wrestling with.
-
Question 1: Location. I keep going back and forth between putting the batteries in the "equipment" space behind the pass-through wall and putting the components on the wall in the pass-through storage or putting everything into the front/nose compartment areas. By going to the nose, it gives me easier access to the batteries if I need to sperate/balance them (using 12V batteries in series) and leaves the pass through completely open. The downside is it forces me to pull the AC power up to the nose and then back to the panel vs just a 12VDC run up to the front factory distribution bar and I lose some storage space. Curious what others have done and if you have any pro's / con's to share?

Question 2: I'm planning to use Victron components and have been looking at the Multiplus II 2x120 and the Quatro II 2x120. Basically, both are the same inverter/charges with the addition of a second line in on the Quatro. I was thinking I could use this 2nd line in as a charging source while towing by using the 1500watt 120v AC output in the bed of the truck (F450 with the generator option). By using the second inbound line I could limit set the power pull from the Victron unit and not have to remember to do it every time I moved. Since I have a 24V battery bank this seemed easier than DC to DC from the truck. I'm curious if others have added a plug to the nose of their trailers and used the AC out from the truck to charge while driving?

Thanks for your input.

I can't provide 310RL specific advice, but for option 1, I did something similar in a Delta. Since you are already pulling 6/3 from the inverter to the breaker panel, pulling 2 wasn't that much more difficult. You can use the existing line going to the panel and connect to a hard-wired surge protector or install a junction box then go to the inverter.

Another thing to take into account is the DC line will be handling a lot more current. A shorter run there may help keep from going to a lower gauge wire.

I wrestled with the location of my power system as well. Finally, I decided I didn't want all the equipment in the same area as PEX water lines. It would only take one busted/leaking PEX connection and I could be out a LOT of money in Victon gear.

I just installed a Victron "Orion" DC-to-DC charger in our 340RL and am VERY pleased with the preformance. Using 4AWG wire, I run it at 40 amps to the RV. I know it can do 50 amps, but I also have 2000 watts of solar on the roof, so I hardly ever need the full 50 amps from Orion, but if I do, it is a simple click on the app to move from 40 to 50 amps.

In the image below you will see a red X...that is where my Orion is now installed. I need to get out there and take a new picture.

I am also in the process of upgrading my electrical to 24V. Currently have two 310 W 12V batteries in Serial supporting 24V with room for 2 more 24V batteries connected parallel to the serial pair for 900W. I have e 410W Bifacial panels for a max of 1-40 W on the roof via a Renogy 60A.
Installed a Victron M10 Distributor, Victron 1K Amp Smart Shunt, Victron Orion 12/24 v 15 Amp DC DC Charger, and a Cliena 24V step down 12V 100A 1200W DC/DC Voltage Converter. The final component is a 6000W ZAPower Pure Sine Split Phase Low Frequency Inverter/Charger integrated Transfer switch w auto start Generator capability. I am looking for assistance connection up the Inverter to avoid complications.
