2x Phoenix 12/500 with one GX Device

Is it possible to use 2x Victron Phoenix 12/500 in one system? (same battery but just two inverters) From what i can find the phoenix 12/500 doesn't support parallel operation but I just want to power 2 devices from two inverters (1 device per inverter)

Can't say I've tried it but electrically it has to work. I'm not sure what the GX would make of it though!

I am not sure that it will work! When I tried to run 2 x MultiPlus 3000 without phasing them together, I got an Alarm #3 Expected device error. I wanted to be able to save the idle current 24/7/365 because it is seldom I need the extra power, (on a separate output). Phasing them together, and switching off the slave, gave (off course) same error. Trying to attach two different Multiplus, a 3000 and a 1600 gave also same result.

Connecting their outputs together is dangerous as they are not in sync, don't do that! My test was only to see how the GX would handle two separate devices.

Hi @xPatrik,

There are limitations, please read this section of the GX manual for more details and post back if it's still not clear - Connecting multiple VE.Bus systems to a single Cerbo GX
