Phoenix Inverter Smart with Autotransformer

I'm designing an off grid system and I'd potentially like to use a Phoenix Inverter Smart with a Victron Autotransformer. The photo below is what I want to do:

My question is where should I attach the ground relay control (shown above) and is this setup compatible with the Phoenix Inverter smart?


From the Victron Autotransformer manual (page 3), I see that,

From the Phoenix Inverter Smart manual (page 9), I see that,

Since the system is in a vehicle does that mean I simply need to connect the ground relay control wire to the same ground as the inverter?


Thanks for your help and let me know if you need any more details!

Hi @Ben Zook

Safe design and installation of ground fault equipment in vehicles is not easy, and giving an appropriate level of advice on a site like this is nearly impossible.

There is a safe and informative level of general theory in the current draft of Wiring Unlimited:

I encourage you to read that, continue to understand as much as possible, and then also seek the advice and experience of a suitably qualified local installer/electrician tradesperson.
