MUST CAN BUS MODELS
Some PV & PH range models do have CAN bus communications and the Hubble lithium batteries will communicate with these models over CAN bus. The Must inverter models are too extensive to list, however if you follow the correct instructions on the Must inverter manual to enable Can Bus it will automatically start communicating with the Hubble lithium batteries.
FREQUENTLY ASKED MUST QUESTIONS
Q: How do you setup multiple batteries?
A: Check the manual for a more detailed explanation. You will have to set dip switch settings per battery to give them a unique address. You also have to connect the included RJ45 battery link cables into the "Battery Link" port of each battery. Ensure your master battery dip switch 1 is on, 2,3,4 is OFF. Only the master battery CAN Bus will be enabled.
Q: Do I have to use the communication battery link cables if i dont want to monitor or have communications?
A: Short answer No. However it is recommended to still connect the battery links and set the correct addresses. This also needs to be done if you want to connect a Hubble Cloudlink.
