Votronic MPPT 32A Duo (Dual) 440 Marine Version Solar Charge Controller
Votronic 32A Duo (Dual) 440 MPPT Solar Controller – Humidity-Proof Marine Version
Ideal for High-Quality Campers, Caravans, and Marine Applications
The Votronic MPP Solar Controller is designed for optimal performance in demanding environments such as boats, caravans, and campers. This humidity-proof marine version is perfect for both caravan and marine use, offering durable and efficient solar energy management even in challenging weather conditions. Both the controller and the display must be installed inside, ensuring reliable, long-lasting performance.
Maximum Power Efficiency with MPP Technology
This MPP (Maximum Power Point) solar controller automatically calculates the maximum power yield of your solar panels several times per minute. By converting excess voltage into a higher charging current, it significantly increases the efficiency of your solar system, ensuring faster charging times and improved power generation – especially during cooler months or cloudy weather.
Key Features:
- Increased Charging Efficiency: Enjoy up to 30% more charging current than conventional controllers due to advanced microprocessor technology (efficiency > 95%).
- Battery Protection: Prevents overcharging with a controlled charging voltage, ensuring the longevity of your batteries.
- Dual Battery Charging Ports: Automatically charges both your main board battery and starter battery, with trickle charging support.
- Unattended Charging: Equipped with safety features against overload, overheating, reverse polarity, and discharge.
- Parallel Operation: Seamlessly works alongside other power sources like wind turbines or onboard generators.
Battery Compatibility and Customization
- Supports Multiple Battery Types: Easily switch between charging lead-gel, AGM, lead-acid, and LiFePO4 batteries, with built-in protection for lithium systems.
- Battery Temperature Sensor Option: For optimized battery performance, especially in extreme temperatures, the controller can be connected to an optional battery temperature sensor (Order No. 2001).
Additional Features for Enhanced Control
- Solar System Monitoring: Compatible with the Votronic Solar Display LCD-Solar Computer S for real-time monitoring of your solar power system.
Applications:
- Marine and boat applications
- Campers, caravans, RVs
- Off-grid solar setups
