Pure Sine Wave MPPT Hybrid Solar Power Invertor off-Grid 780W
China Pure Sine Wave MPPT Hybrid Solar Power Invertor off-Grid 780W, Find details about China Solar Controller, PWM from Pure Sine Wave MPPT Hybrid Solar Power Invertor off-Grid 780W
own technology. It's main topology adopts in Buck conversioncircuit, and uses MCU to adjust the solar panels working point
intelligently in order to make the solar panels output is maximum power. When the circumstances change, the working point of
solar panels deviate from the maximum power point, MCU will adjust the solar panels working point based on MPPT calculation
to make the solar panels back to the maximum power point again. Compared with PWM controller, MPPT can increase the
output power of solar panels by 5%-30%. The output power increasing proportion is affected by the factors such as solar
panel property, humidity and light intensity. The controller uses wall-mount installing. Connecting terminal makes the wiring
area bigger and wiring loss less.
