Victron SolidSwitch 104
The SolidSwitch 104 will switch DC loads of up to 70V/4A and can be controlled by a low power digital signal.
The DC load can be resistive, capacitive or inductive (such as the coil of a high-power contactor).
The SolidSwitch is not reverse polarity protected and not short circuit proof.
Victron smallBMS
A simple and low cost alternative to the VE.Bus BMS V2
The smallBMS can replace the VE.Bus BMS V2 in several applications. It is however not suitable for use with VE.Bus MultiPlus and Quattro inverter/chargers: it has no VE.Bus interface. The smallBMS is intended for use with Victron Smart LiFePo4 batteries with M8 circular connectors.
The smallBMS has two outputs, similar to the VE.Bus BMS V2.
