So looking for some install guidance for what I can’t seem to find and unchartered territory. I’m probably the only one trying to do this and Progressive Dynamics Technical Engineer was absolutely no help even for connection advise or confirmation of compatibility so I am taking this on and even making my own data cables. Most people would toss these inverters and use the MultiPlus II but I had a mission to lose as little storage space as possible and worked out very well.
I have 2 Progressive Dynamic Inverters in my Airstream. 1000w which came OEM that covers drivers side outlets and another 2000w I added with a junction box to include passenger side outlets, MW, and a 15k BTU A/C. System works great. I do all the upgrades myself. 500Ah Battleborn Lithium(which I’m going to likely replace with 1200Ah Epoch bank in same footprint)with Victron MPPT, Smartshunt, DC to DC charger and now finally adding a Cerbo GX into the mix. The 2 x PD inverters do support RV-C via a Molex connector so wanted to tie them into the VE Bus ports of the Cerbo using custom cables with RJ45 conductive wiring.
The Cerbo manual says only a single inverter should be plugged into one of the two VE Bus ports. Also saying if you wanted to add another inverter to the same Cerbo to use the MK3-USB interface but doesn’t get into further. That device seems to be more used to program a Multiplus II and other VE products when customization settings required.
How do I go about capturing the AC and DC load info of both of these inverters into the Cerbo? What happens if I do connect both PD inverters independently to each open VE Bus port on the Cerbo? Or do they need to connect to the Ve Can port as RV-C devices? Im not sure if the PD inverters are compatible to the VE Bus ports of the Cerbo.
I just want to this correctly and smart so works properly but most importantly don’t damage anything in the configuration.
Appreciate proper guidance here.
