SmallBMS
Charger
Load
The smallBMS controls loads and chargers via “load disconnect” and “charge disconnect” signals
The VE.Bus BMS
The VE.Bus BMS directly communicates with a Victron Energy inverter/charger system via the VE.Bus. Just like the smallBMS, it
also features a “load disconnect”, a “charge disconnect” and a pre-alarm contact.
• In the event of low cell voltage, the VE.Bus BMS will send a “load disconnect” signal to turn off the load(s) and it will also turn
the inverter of the inverter/charger off.
• Prior to turning loads off, it will send a pre-alarm signal warning of imminent low cell voltage.
• In the event of a high cell voltage or high/low cell temperature, the VE.Bus BMS will send a “charge disconnect” signal to turn
the charger(s) off and it will also turn the charger of the inverter/charger off.
The mains detector ships together with the VE.Bus BMS.
Special programming of the inverter/charger is required for the BMS to be able to communicate with the
inverter/charger.
