240v EV Charger on AC-Out-2 of Quattro II

[Robert T]

I'm planning on putting a 240v Emporia level 2 EV charger on the AC-Out-2 of my 12v Quattro II 3000 2x120v Inverter. This will only be available when I'm hooked up to shore power and the inverter is in passthrough mode. I'm aware that I will probably have to limit charging to 32A since the connection maxes out at 50A/240v (edit: the Emporia maxes out at 48A) and most RV outlets don't do very well at max rating continuous. The Emporia has smart load management which should work well with this setup. I was planning on putting a 40A breaker on my charger.

Any advice would be greatly appreciated! Can anyone think of any problems I might run into with this setup?

Thank you, I <3 this forum

[edit] for clarity my RV has a standard dual phase 50A inlet.

I run dual Quattro 5000 in split phase and use my AC out2 for a 240V ev charger or buddy plug at 50A/240V. I have the quattro 1's which has 100a on out1 and 50a on out2. Since my inverters are split phase I program AC out2 to turnoff at 50% so I can charge my ev off batteries, you can leave the default so it'll only be on when on shore since itll be 120v when inverting.

I wired it from the inverter to a single gang breaker box (like a home AC type) then to a 50a/240V shore plug box with a cover. Have it in a basement bay next to the inverters and crack the bay door if something's plugged into it. I'd suggest you do the same then plug the EV charger into it. This way you can easily unplug and use for anything else. I'm thinking about buying an electric grill/cooktop type thing

You should be able to get 40a perfectly fine (80% of 50a) but I think most L2 chargers are 32A anyways.

Oh you are right! I'm limited to 32a anyhow so this should work out perfect, thank you!
