Features
Advanced MPPT Technology
Utilizes the PowerCatcher MPPT algorithm for over 99% tracking efficiency, even in challenging environmental conditions. It provides a fast response to maximize solar energy harvest, achieving up to 20% more energy than PWM controllers.
Dual Charging Inputs
Supports simultaneous or independent charging from both solar panels and the vehicle alternator. It is compatible with both conventional and smart alternators operating on 12V/24V systems.
Wide Battery Compatibility
Compatible with a range of battery types including lead-acid (sealed, gel, flooded), lithium iron phosphate (LFP), and custom battery profiles. Features temperature compensation for lead-acid batteries, providing -3mV/°C/2V adjustment.
High-Efficiency Conversion
Achieves up to 96% conversion efficiency. Employs Buck MPPT for solar input and Buck/Boost technology for alternator input to optimize power conversion.
Smart Protection & Monitoring
Includes comprehensive protection mechanisms such as over-temperature, over-charge, over-current, and reverse polarity protection. Real-time monitoring is available via Bluetooth or wired connections (CAN, RS485, TTL) using a dedicated mobile app.
Flexible Charging Modes
Offers adjustable solar/alternator priority settings. Features a three-stage charging process (Bulk/Boost/Float) for lead-acid batteries and a two-stage process for lithium batteries.
