Why lithium ion battery need communications
For lithium-ion and LiFePO4 batteries, SOC is particularly important because it directly influences how the battery performs, how long it lasts, and how efficiently it interacts
Communication between the inverter and the battery takes place via the battery communication cable via CAN bus. Additionally required material (not included in the scope of delivery): 1 battery communication cable for the communication between inverter and battery
If only one battery is available, insert the plug into the jack BAT1. If multiple batteries and/or an automatic transfer switch are available, insert the communication connection of the first battery into the jack BAT1 and connect all other communication cables in succession to the respective jacks.
Insert the cable gland into the opening and tighten it with the counter nut from the inside. Lead the communication cable into the inverter. Trim the cable shield to a length of 15 mm and fold it over the cable sheath. Strip the insulation on the insulated conductors each by 6 mm. The CAN L and CAN H must be a twisted pair.
