Victron Energy SCC940100100 Temp. Sensor for BlueSolar PWM-Pro Charge Controller
Victron Energy SCC940100100 Battery Temperature Sensing for the BlueSolar PWM-Pro.
Product Overview
The Victron Energy SCC940100100 is the dedicated battery temperature sensor accessory for the BlueSolar PWM-Pro charge controller. When connected, it allows the PWM-Pro to monitor battery temperature and automatically adjust charge voltage setpoints to compensate a process known as temperature-compensated charging.
Temperature compensation matters because a battery's correct absorption and float voltage changes with temperature. A battery in a cold engine bay needs a higher charge voltage to reach full state of charge; the same battery on a hot summer day needs a lower voltage to avoid overcharge and electrolyte loss. Without temperature sensing, a fixed-voltage charge controller uses a single setpoint regardless of conditions either undercharging in cold weather or overcharging in heat. In Australian climates where battery compartment temperatures can swing dramatically between seasons and times of day, this sensor provides a meaningful improvement in both battery charge quality and long-term battery health.
Key Specifications
- Part Number: SCC940100100
- Function: Battery temperature sensing for temperature-compensated charging
- Compatible Device: Victron BlueSolar PWM-Pro charge controller
Features & Benefits
- Temperature-Compensated Charging — Enables the BlueSolar PWM-Pro to automatically adjust its charge voltage setpoints based on measured battery temperature. Warmer batteries receive a lower charge voltage to prevent overcharge; cooler batteries receive a higher voltage to ensure complete charging. This protects battery health across varying ambient conditions and extends battery service life.
- Critical for Variable-Temperature Environments — Temperature compensation is particularly valuable in installations where battery compartment temperature changes significantly — vehicle engine bays, outdoor battery enclosures, marine bilges, and caravan battery boxes all experience wide temperature ranges. A fixed charge voltage calibrated for 25°C will undercharge at 0°C and risk overcharging at 45°C without compensation.
- Purpose-Built PWM-Pro Accessory — Designed specifically for the BlueSolar PWM-Pro charge controller. Not confirmed as compatible with other Victron charge controller models — verify compatibility with your specific controller before purchase.
- Protects Lead Acid Batteries — Temperature-compensated charging is especially important for flooded lead acid and AGM batteries, where overcharge accelerates electrolyte loss and plate degradation. Lithium batteries typically require a different approach to temperature management — confirm your battery chemistry's requirements before relying on temperature compensation.

Frequently Asked Questions
What does a temperature sensor do for a charge controller?
It allows the charge controller to monitor battery temperature and automatically adjust charge voltage setpoints to match — a process called temperature-compensated charging. This prevents overcharging in hot conditions and undercharging in cold conditions, improving charge quality and extending battery life.
Do I need this sensor if my batteries are in a stable indoor environment?
If your battery compartment maintains a relatively stable temperature close to 25°C year-round, the benefit is minimal. In vehicles, caravans, marine installations, and outdoor enclosures where temperature swings widely between seasons, times of day, or climate zones, temperature compensation provides a meaningful improvement in charging accuracy and battery longevity.
Is this sensor compatible with Victron MPPT or SmartSolar charge controllers?
No — this sensor is designed for the BlueSolar PWM-Pro specifically. SmartSolar and BlueSolar MPPT controllers use different temperature sensing accessories and interfaces. Confirm the correct sensor for your specific controller model from the Victron documentation before purchase.
Where should the temperature sensor be attached?
Temperature sensors for charge controllers are typically attached directly to a battery terminal or the battery casing to measure battery temperature accurately. Specific installation instructions for this sensor are not confirmed in the available product data — refer to the Victron BlueSolar PWM-Pro manual for correct sensor placement.
Is temperature compensation suitable for lithium batteries?
Temperature compensation is primarily designed for lead acid chemistry batteries (flooded, AGM, gel). Lithium battery systems typically require a fixed absorption voltage regardless of temperature, and some lithium BMS units manage temperature independently. Confirm your lithium battery manufacturer's charging requirements before enabling temperature compensation.
