Smart BMS CL 12/100 Cable

This cable is designed to connect Victron Energy BMS (Battery Management System) products, such as the Smart BMS CL 12-100 and the smallBMS, to certain MultiPlus inverter/charger models that lack a VE.Bus interface.

The Victron Energy part number for this cable is ASS070200100.

The SKU (Stock Keeping Unit) for this product is ASS070200100.

The primary function of this cable is to allow BMS units without a VE.Bus interface, such as the Smart BMS CL 12-100 and the smallBMS, to control MultiPlus inverters/chargers using their charge/alternator disconnect outputs.

This cable uses the load disconnect and charger disconnect outputs (Load Disconnect) from the Smart BMS CL 12-100, or the load/charger outputs (Load/Charger) from the smallBMS, to control the start and stop of compatible MultiPlus models.

No, this cable is a specialized cable designed by Victron Energy to establish a specific control connection between some of their BMS and MultiPlus inverters/chargers, in the absence of a VE.Bus interface on the BMS.

The main advantage is to allow users of systems equipped with a Smart BMS CL 12-100 or a smallBMS to control MultiPlus inverters/chargers (500VA – 1600VA, Compact 800VA – 2kVA, and MultiPlus-II) that do not have a VE.Bus interface, thus ensuring essential power management.

This cable is compatible with the Victron Energy Smart BMS CL 12-100 and smallBMS.

This cable is compatible with the following inverter/charger models:

MultiPlus 500VA – 1600VAMultiPlus Compact 800VA – 2kVAMultiPlus-II

This cable is specifically designed for MultiPlus units that do not have a VE.Bus interface or for BMS units that lack one. If your MultiPlus or BMS has a VE.Bus interface, other digital integration solutions such as the Cerbo GX are typically used.

No, this cable is not compatible with all MultiPlus models. It is specifically designed for MultiPlus 500VA – 1600VA, MultiPlus Compact 800VA – 2kVA, and MultiPlus-II.

This cable is compatible with MultiPlus units ranging from 500VA to 1600VA for the standard series, and from 800VA to 2kVA for the MultiPlus Compact series, as well as all MultiPlus-II models.

Yes, this cable can be used to connect a smallBMS to a MultiPlus-II, allowing the smallBMS to control the inverter/charger.

No, if you are using a Cerbo GX, you generally will not need this cable. The Cerbo GX, along with other Victron BMS units equipped with a VE.Bus interface, provide full digital integration via the VE.Bus bus, making this cable unnecessary for these configurations.

For MultiPlus 500VA-1200VA models, connect the black wire to the ON terminal and the red wire to the (+) terminal of the remote on/off connector.

For the MultiPlus Compact 800VA–2kVA models, connect the black wire to the center terminal and the red wire to the right terminal (IN) of the remote on/off connector.

For MultiPlus-II models, the black wire must be connected to the lower terminal (-) and the red wire to the upper terminal (+) of the remote on/off connector.

For the MultiPlus to operate, the load/charger disconnect outputs (Load/Charge Disconnect) of the Smart BMS CL 12-100 or the load/charger outputs (Load/Charger) of the smallBMS must be in the « High » state.

After a shutdown due to low battery voltage, you must run the alternator or use a battery charger on the primary side of the BMS to reset the system. The MultiPlus will then power up and start charging (if connected to an AC power source).

The cable must be connected to the remote on/off connector of the relevant MultiPlus model.
