How It Works
Three integrated systems work together to deliver clean, optimized DC charge current — automatically.
Propane-Driven Alternator
A propane engine drives a high-efficiency permanent magnet alternator, producing clean raw DC power free from altitude limitations and grid dependency.
MPPT Charge Optimization
An integrated MPPT charge controller continuously tracks and optimizes power delivery to your battery bank, maximizing charge efficiency regardless of load conditions.
ESP32 Auto-Throttle
An onboard ESP32 microcontroller reads real-time battery demand and automatically adjusts engine throttle — no manual tuning, no wasted fuel.
