The PDC25 seamlessly converts your vehicle’s 12V or 24V alternator output into the optimal charging voltage your batteries need — ensuring a full charge, longer lifespan, and reliable performance. Using advanced synchronous switching technology, it delivers exceptional efficiency of over 94% at full load.
With intelligent power management, the PDC25 supports dual energy sources at the same time — giving solar priority. When solar alone isn’t enough, it automatically blends alternator and solar power to keep your system fully energized.
