70 amp solar charge controller adopts MPPT technology to be higher efficiency up to 98%, uses big aluminum heatsink to natural cooling and quiet operation. Big LCD display and LED indicators shows solar power system's working status.
Users not only can read but also can program the parameters on the 80 amp solar charge controller directly by the LCD display. Parameters include the charging current, charging voltage, load current and voltage, ect.
Standalone Solar Power System:
Combined MPPT technology and DSP controller and Battery Temperature Sensor (BTS), JMTL-MPPT charge controllerwill convert best voltage to charge battery based on varied temperatuer. Compared to PWM charge controller, it allows your solar panels to operate at their optimum power output voltage at all times and in all weather conditions to provide higher efficiency up to 98% with lower power loss. Integrated 80 amp MPPT charge controller with solar power inverter, solar panels and solar power battery packs, it can become a standalone solar power system to generate green power for your home appliances. JMTL series mppt charge controller will convert power to charge solar power battery and then provide power to home appliances via solar power inverter.
