Description

The Victron Energy Cyrix-Li-load 24/48V-120A intelligent load relay is a BMS-controlled high-current switch for 24V and 48V LiFePO4 systems. It disconnects DC loads when the VE.Bus BMS load-disconnect signal goes inactive, helping protect lithium cells from damaging undervoltage. Rated for 120A continuous current, it supports demanding battery-powered DC systems.

When battery voltage recovers, the relay can reconnect after a 30-second delay, with three retry attempts before remaining disconnected. With IP54 protection, low open-state consumption and compact 46 x 46 x 80 mm dimensions, it provides dependable load control for lithium installations.

Key Features

Smart Control for Lithium Loads

Lithium Load Protection

Disconnects DC loads when the BMS signals imminent lithium cell undervoltage.

Automatic Recovery

Reconnects loads after 30 seconds when battery voltage and the BMS signal recover.

Retry Lockout

Stops reconnecting after three failed attempts until the battery is being recharged.

24/48V Compatibility

Supports 24V and 48V systems: 120A at 24V, with 40A breaking capacity at 48V.

Low Open-State Draw

Frequently Asked Questions

Is Volts Energies an authorized Victron Energy dealer?

Yes. Volts Energies is an authorized Victron Energy dealer and distributor in Canada. All Victron products sold at Volts Energies are genuine, covered by full Victron warranty, and eligible for Victron technical support.

What is the Victron VRM portal?

The Victron Remote Management (VRM) portal is a free cloud-based monitoring platform that displays real-time and historical data from your entire Victron system. It is accessible from any browser or mobile device and requires a Victron GX device (such as the Cerbo GX) connected to your system.

What is the difference between Victron MultiPlus and Quattro?

The MultiPlus has one AC input and combines an inverter, charger, and transfer switch in one unit. The Quattro has two AC inputs, it can accept both grid and generator power simultaneously and switch automatically between them. The Quattro is used in larger and more complex off-grid and hybrid systems requiring full redundancy.

Can I use Victron products with non-Victron batteries?

Yes. Victron MPPT controllers, inverter chargers, and battery chargers are compatible with most third-party batteries including Pylontech LiFePO4 batteries stocked at Volts Energies. Some advanced integration features such as dynamic charge current control require compatible BMS communication with GX devices.

What is the VictronConnect app used for?

VictronConnect lets you configure, monitor and update all Victron Smart-series products wirelessly over Bluetooth from any iOS or Android device, set charge parameters, view live data and read history.

Do Victron products work in cold Canadian winters?

Yes. Victron inverters and chargers are rated to perform reliably from −40°C to +65°C, making them well suited to year-round Canadian off-grid, cabin and marine use.
