Victron Energy SolidSwitch 104 – Solid State DC Load Switch 70V/4A (BMS800200104)

The SolidSwitch 104 is a low-power solid-state switch engineered to control DC loads up to 70 volts and 4 amps. It can be triggered by a small digital control signal as low as 3.3V, making it suitable for modern BMS-driven systems or microcontroller logic. Its low self-consumption, just 0.04Ah/month, offers a significant advantage over mechanical relays, especially in energy-sensitive lithium battery environments.

Key Use Cases

Control external alternator regulators in Victron Lithium battery systems (e.g., Balmar or Mastervolt Alpha Pro)
Switch low-to-medium power DC loads (up to 4A), such as lights or control devices
Expand the number of chargers connected to the ATC (allow-to-charge) output of a Victron BMS
