VE.Bus BMS on/off switch

In VE.Bus BMS manual a "System on/off switch" is included in wiring diagrams. What is the purpose of that switch? In my understanding the BMS should always monitor the litium batteries and never be turned off. If the switch turns BMS off, it's useless. But does it turn something else on and off as the name "System switch" suggests?

Hi @Simo Hassi,

one reason is storage mode, where you don't want anything depleting your lithium battery.
