Common Questions
What is MPPT technology and why is it important?
MPPT (Maximum Power Point Tracking) technology continuously monitors the voltage and current output of your solar panels to find the optimal power point. This ensures maximum energy is harvested from your panels, especially beneficial during cloudy conditions or when light intensity changes, improving energy yield by up to 30% over traditional PWM controllers.
How can I monitor and configure this charge controller?
The BlueSolar MPPT 100/50 features a VE.Direct communication port. You can connect optional accessories such as a Victron VE.Direct Bluetooth Smart dongle to pair with the VictronConnect App on your smartphone or tablet, or an MPPT Control panel for direct display and programming. These accessories allow for real-time data monitoring and customisation of charging parameters.
What battery types are compatible with this controller?
This controller is compatible with a wide range of battery types, including AGM, Gel, Tubular plate, and Lithium batteries. Its flexible and programmable charging algorithm, along with temperature compensation, ensures optimal and safe charging for various battery chemistries, helping to prolong their service life.
Installation Notes
- Mount vertically on a non-flammable surface, ensuring adequate ventilation (minimum 10cm clearance above and below).
- Install close to the battery, but not directly above it, to prevent damage from gassing.
- Use appropriate fuse protection for the battery supply as per manufacturer guidelines (e.g., 55A-70A for MPPT 100/50).
- Ensure correct wire gauge for PV and battery connections to minimise voltage drop and ensure safety.
- Avoid ambient temperature differences of more than 5°C between the solar charger and the battery for accurate temperature-compensated charging.
Before You Buy
- Verify your total PV array open circuit voltage does not exceed 100V.
- Confirm your total PV array power is within the controller's limits (700W for 12V, 1400W for 24V systems).
- Ensure your battery bank's nominal voltage is 12V or 24V.
- Consider if you require remote monitoring or an external display, as VE.Direct accessories are sold separately.
- Check physical dimensions (130 x 186 x 70 mm) to ensure suitable mounting space.
Always verify product specifications and compatibility with your existing solar system components before purchase. This Victron product is covered by a 5-year manufacturer's warranty.
