Have a news van that has an APD 24v aux alternator installed. Plan to add eg4 ll v2 battery with a TE contactor LEV200A5NAA, MultiPlus II 24v 3000, BMV-712. The van was setup with a color control gx and a fancy panel for mounting and display and either had a Quattro or multiplus in it. I’m not quite sure how the communication between the MP, CCGX, and the eg4 battery is supposed to work. Should I just use the bmv-712 to monitor the battery? The eg4 has can capable communication and I have seen people make cables and plug them into cerbos but no one with ccgx. I understand it’s not supported any longer but hoping to make this work. The contactor is rated for 500A and the alternator has max output of 300A, the battery has 200A charge capability. I think the relay on any of the bmv, MP, or the ccgx should be able to control the contactor if the charging exceeds the battery capability. Cheers, J
CCGX does not have CAN capability.XXX<< correction one port with 2 sockets.
MP <> CCGX is VE-bus, uses UTP type cable.
BMV-712.<> CCGX is VE direct - special cable needed.
Yes with proper configuration.
Perhaps you need to upgrade to a Cerbo?
The ccgx has two rj45 VE Can ports on the back, which are nmea2000 3rd party connections allowed, according to a data communications with ve products pdf. On the ccgx diagram in the packaging it shows skyalla-i or mppt 150/70 or mppt 150/85 being able to connect to it. Is it only for solar chargers or is this information conflicting?
If I were to get a cerbo, could I use the ccgx as a display and secondary device?
Sorry, the CCGX does have one VE-can bus, the Cerbo has two.
See topic below for info on connecting multiple GX devices. The CCGX is older and may struggle. This is not in the manual.
