Victron BatteryProtect 48V 100A Disconnect

The Victron BatteryProtect 48V 100A disconnects nonessential loads before a 48V bank is excessively discharged, in a unidirectional design.

Unidirectional is the constraint that decides how it must be wired: current flows only from the Battery terminal toward the Load terminal. Connecting it backward does not simply reverse the function, it prevents the device working as intended. The terminals are labeled for a reason and swapping them is a real installation error.

This is the non-Bluetooth version against the Smart BatteryProtect, so thresholds are set with the programming pin rather than an app. That suits an installation set once and left alone, and it costs less than the Smart version for the same protection.

It can be installed in a load circuit or in certain charging-control applications. Shedding selected loads at a low-voltage threshold preserves the reserve for critical functions, which a blanket cutoff taking everything would not. Explore more Relays, Combiners & Disconnects.

• Current flows Battery to Load only
• Wired backward it does not work at all
• No Bluetooth: thresholds set with the pin
• Sheds selected loads, keeping critical reserve
