There is a CCGX with 3x Blue Solar 150/85 mppts connected via VE.can with a terminator in the other port.
Need has arisen to connect lithium batteries which require can coms to control charging. Dilemma is whether can connect the BMS cable to the other Ve.can port occupied by the terminator or need to upgrade to CerboGX and use the other Ve.can port with terminator for BMS and the other port with terminator for Blue Solar?
