Victron SolidSwitch 104:
The SolidSwitch 104 switches DC loads of up to 70V/4A and can be controlled by a low power digital signal. It has three typical use cases:
1. Control an external alternator regulator, such as a Balmar or Mastervolt Alpha pro in a Victron
lithium system.
2. Switch a DC load, such as a light. A low power control circuit, max current drawn will only be 100
?A, can then control a load of up to 4 Amps.
3. Increase the number of chargers that can be wired to the ATC (allow-to-charge) output of a
Victron BMS.
