Victron Energy temperature sensor for solar charge controller
This temperature sensor is an ideal accessory for the Victron BlueSolar PWM-Pro solar charge controller.
It allows for continuous measurement of the battery temperature and ensures that the charge controller applies temperature-compensated charging voltage.
As a result, the battery's lifespan, safety, and the overall efficiency of the solar system are significantly improved.
Why is measuring battery temperature important?
The charging voltage of lead-acid, AGM, gel, and lithium batteries greatly depends on temperature.
If the charge controller operates with a fixed voltage, then:
- at low temperatures undercharging may occur, reducing capacity,
- at high temperatures overcharging, gas formation, and accelerated aging may occur,
- the risk of battery faults, failures, and unexpected shutdowns increases.
Temperature-compensated battery charging provides an optimal charging curve,
and is a prerequisite for the long-term, reliable operation of the solar system.
Main features and functions
- Accurate temperature measurement near the battery
- Automatic temperature compensation in the BlueSolar PWM-Pro charge controller
- Reliable data transmission to the charge controller
- Easy connection and commissioning
- Stable, long-lasting sensor
- Compatible with various battery technologies
How does temperature-compensated battery charging work?
The sensor continuously measures the temperature of the battery's environment and transmits this information to the solar charge controller.
Based on this, the controller adjusts the charging voltage, so:
- at low temperatures, it applies a higher charging voltage,
- at high temperatures, it reduces the voltage to avoid overcharging,
- it optimizes the energy transfer from the solar system to the battery.
This process is fully automatic, requiring no manual intervention from the user,
ensuring that the system always operates according to the current temperature conditions.
Benefits in solar systems
The use of the temperature sensor is particularly recommended in any solar system where reliable power supply and long battery life are important. It is especially useful in:
- RVs, caravans, and boats' solar systems,
- off-grid energy supply for weekend houses, holiday homes, and farms,
- standalone and hybrid solar systems,
- outdoor installations exposed to large temperature fluctuations.
Temperature-balanced battery charging reduces maintenance needs,
mitigates premature battery replacement costs, and increases the return on investment of the solar system.
Simple installation and use
Connecting the sensor does not require special expertise.
Simply follow these steps:
- Disconnect the solar charge controller and the battery.
- Connect the temperature sensor's connector to the appropriate input of the BlueSolar PWM-Pro.
- Mount the sensor near the battery, as close to the housing surface as possible.
- Reconnect the battery and solar modules, then turn on the system.
The charge controller automatically recognizes the connected sensor and immediately begins applying temperature-compensated charging.
Typical application areas
- 12 V and 24 V battery solar systems
- lead-acid, AGM, gel, and lithium battery banks
- residential and small industrial off-grid applications
- telemetry, security, remote monitoring systems' power supply
The temperature sensor is particularly recommended in places where batteries are exposed to significant temperature fluctuations year-round,
as this significantly reduces the risk of overheating and deep discharge.
