Dear Victron community,
I’m going to use a Pylontech UP2500 (24V) in a campervan = offgrid system. Please find attached the first version of my electrical diagram.
I've read carefully the document written by Victron staff on how to parameter GX system in DVCC mode (https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom)
I used a full Victron system in the past, the Vebus BMS was able to stop charge/discharge process automatically, and I would like to do the same thing in my setup thanks to the Cerbo GX.
Unfortunately, products such as Orion Charger/converter or battery protect don’t have any VE BUS or CAN communication port to allow direct charge/discharge communication. But both has the capability of being switched remotely. My idea is to use the two relays in alarm mode of the Cerbo to trigger the switch of the Orion and Battery protect in case of error sent by the Pylontech BMS.
For instance, in case of the Orion Tr Smart charger, wire the H pin (Figure c.3 manual).
Do you have any suggestion for this particular setup ? My French Victron distributor told me it was technically feasible but any advice is welcomed.
