Victron Battery Protect 48V-100A: Advanced Power Management for Industrial and Off-Grid Systems

Note: "Victron Battery Protect" units are NOT Bluetooth-enabled. See "Victron Smart Battery Protect" units if Bluetooth connectivity is required.

Important Considerations for Inverter Connection

It's crucial to avoid connecting inverters or inverter/chargers directly to the BatteryProtect's DC inputs to prevent reverse current damage. Instead, use the BatteryProtect to control the inverter or inverter/charger via its remote port, as illustrated in the manual.

Essential for Preserving Battery Health in 48V Systems

The Victron Battery Protect 48V-100A is key to safeguarding batteries in high-power applications from complete discharge. Ideal for industrial setups and off-grid systems, it disconnects non-essential loads before the battery is drained or too low for operational needs.

Uni-Directional Current Management for Enhanced Safety

Designed as a uni-directional device, the BatteryProtect ensures safe current flow, either to a load or from a charger, providing reliable over-voltage protection for sensitive equipment in demanding environments.

Specialized for High-Voltage Systems and Lithium Batteries

With an intelligent system that caters to 48V setups, this device is also optimized for Li-ion batteries, offering a unique control mode via the VE.Bus BMS and functioning as a charge interrupter for advanced battery care.

Ultra-Low Consumption for Energy Efficiency

The BatteryProtect's minimal energy consumption is vital in maintaining system efficiency, particularly crucial in 48V setups like large solar arrays and industrial machinery.

Over Voltage and Ignition Protection for Industrial Safety

Equipped with robust over-voltage protection and MOSFET switches, the BatteryProtect ensures safe and spark-free operation, a must-have for industrial and off-grid applications.

Versatile Remote Switch Functionality

Its ability to function as a remote switch offers additional convenience, allowing for remote operation of various devices, an essential feature in large-scale and remotely managed systems.

Smart Alarm and Load Management

The delayed alarm feature and intelligent load management system of the BatteryProtect ensure seamless operation, maintaining system integrity and preventing unnecessary power interruptions.

The Victron Battery Protect 48V-100A is an ideal choice for managing high-capacity battery systems in industrial and off-grid applications, ensuring optimal performance and extended battery life.

Off-Grid and Backup

The presence of a functional electricity grid is not always as obvious as it would seem to be. An insufficient infrastructure is often the cause for an unreliable grid. Things become even more difficult when there is no grid at all. And yet you are in need of a reliable electricity supply. A local and properly functioning system is the only answer at this point. Victron Energy offers you such an answer. We are proud to offer you our modern translation for freedom and independence. Energy, Anytime, Anywhere

Energy Storage

As more solar and wind power comes on line, it becomes increasingly difficult and expensive, to ensure stability of the grid. Intermediate energy storage is therefore rapidly becoming an essential tool to keep power fluctuations on the grid within manageable limits. Moreover, as feed-in tariffs are decreasing, the business case for a home energy storage system that increases self-consumption becomes more solid every day. Intermediate energy storage increases self-consumption of harvested solar and/or wind power. The natural next step is 100% self-consumption and independence from the grid.
