The Victron Energy Temperature Sensor for Quattro, MultiPlus and GX Device (part number ASS000001000) is a compact accessory that gives your Victron system a way to read temperature. It is made for owners of Victron Quattro and MultiPlus inverter/chargers and compatible GX devices who want to keep a closer eye on battery conditions in a home backup system, an RV, an off-grid cabin, or a mobile work rig. Batteries have opinions about heat and cold, and this small sensor helps your system hear them out.
One important note up front: this is not the temperature sensor for the BMV-712. If you are shopping for a BMV-712 sensor, that is a different accessory.
This sensor is designed for Victron Quattro and MultiPlus inverter/chargers and for GX devices such as the Cerbo GX and Venus GX. Pairing an accessory with the product family it was made for takes a lot of the guesswork out of system building.
Temperature has a real effect on battery performance and lifespan. Adding a dedicated sensor gives your Victron equipment a temperature reading to work with, rather than leaving it blind to what is happening around the battery bank. Exactly how each device uses that reading depends on the device and its settings, so check your unit's documentation.
Power systems tend to live in cramped places: RV bays, equipment closets, battery boxes, and van conversions. This sensor measures 7 x 4 x 0.5 inches and weighs 0.2 lbs, so it will not add noticeable bulk to your build. Confirm your mounting location and cable routing before you install.
Victron has a lot of look-alike accessories, and the part number is the safest way to order the right one. This sensor is part number ASS000001000, the same number you will see on Victron's temperature sensor documentation.
A temperature sensor is a quiet accessory, but it earns its keep in any setup where the batteries live in a place that does not stay at a comfortable room temperature.
The honest alternative is skipping the sensor and running the system without temperature input. Plenty of systems do, and nothing breaks on day one. The trade-off is that your Victron equipment has no direct temperature reading from the battery area, which matters most in climates or installations where temperatures swing widely.
Compared with a broader monitoring setup, this sensor is a focused, low-profile accessory. It is not a battery monitor, a shunt, or a full system display. It adds one specific piece of information, and it does it as part of the Victron ecosystem. If you need a temperature sensor for a BMV battery monitor such as the BMV-712, you will need a different Victron sensor.
This is a straightforward add-on, but a few checks will save you a return trip.
This may be a good fit if:
Before you buy, confirm that your specific Victron products support this sensor, and check your unit's datasheet to see whether a sensor already shipped with it. Victron's documentation also lists other supported products beyond Quattro, MultiPlus, and GX devices, so it is worth confirming compatibility for anything else in your setup. Our team is happy to help you sort it out.
