Buck Boost Converter 120W/150W Adjustable Regulated for Solar Charging
The Buck Boost Converter 120W/150W Adjustable Regulated for Solar Charging is a compact DC buck-boost power module that accepts 6–36V input and delivers a stable 0–36V output, up to 150W for the SK-150 model or 120W for the SK-120 model. Its MPPT-enabled design optimizes solar charging efficiency, helping you extract more energy from your panels while protecting your battery and load.
Key advantages include a clear 1.8-inch LCD display (viewable area 38×29 mm), a soft-start to minimize inrush, and a robust protection suite. You get adjustable undervoltage, overvoltage, over-current, and over-power protections, plus anti-reverse and anti-backflow for safe, reliable operation in solar setups. With around 88% conversion efficiency and a typical ripple of about 150 mV peak-to-peak, it delivers steady performance in fluctuating input conditions.
Designed for flexibility, these models support 6–36V input and 0–36V output with precise control by 0.01V/0.001A steps. The SK-150 adds substantial power handling (up to 150W) and includes detailed tuning options, a 5-button interface, and 10 storage groups for quick setup recalls. The SK-150 measures 79×43×50 mm and weighs 108 g. Both variants feature MPPT for solar charging, buzzer feedback, and robust protection features including anti-reverse and anti-backflow.
