The "BMU Number," located at the bottom-left of the screen, serves to identify the quantity of battery modules within the L3 system. This number is automatically displayed when there is proper communication between the battery modules and the BMU. The "Protocol ID" defines the CANBus communication protocol utilized by the L3 system. ID 0 should be selected for Sol-Ark Inverters You can tap on each Fault icon positioned on the right and left sides of the screen to access additional information about faults, including detailed descriptions and common causes. -
Page 23: Operation And Maintenance
The L3 HV series features an integrated aerosol-based fire suppression system at the battery module level. In the rare event of a thermal runaway, the aerosol canister would rapidly deploy, filling the battery module interior with non-toxic agent to suppress any potential fire before spreading. This unique, industry-leading safety capability from Sol-Ark ensures maximum protection for commercial and industrial users. -
