Win-k Series MPPT Solar Charge Controller (Bluetooth)
A rugged, efficient MPPT solar charge controller designed for mobile and outdoor power systems. With an IP54 dust & splash-resistant rating, this controller is ideal for RVs, vans, camping setups, and outdoor equipment where moisture or dust may be present.
Outdoor Durability:
IP54 protection helps shield against dust, light rain, and splashing — perfect for mobile installs or damp environments. (Not submersible.)
Powered by an advanced Maximum Power Point Tracking (MPPT) algorithm, the controller extracts more usable energy from your solar panels — with up to 99.9% tracking efficiency and up to 98% conversion efficiency.
Built-in Bluetooth lets you monitor performance, history, and charging parameters through the free mobile app (Android & Apple), allowing the controller to be mounted out of sight while still giving full access to system data.
Low-Profile Design:
With a thin, compact chassis (just 31.5 mm thick on the WIN2075-K), the WIN Series fits easily into tight RV cabinets, electrical bays, van builds, and battery compartments. Ideal for clean, space-restricted installs.
Suggested Applications
- RVs, trailers, and motorhomes

- Vanlife & bus conversions
- Portable and mobile power systems
- Emergency power & backup systems
- Work & Landscaping Trailers
