Properties of Light
There are several key characteristics of the incident solar energy which are critical in determining how the incident sunlight interacts with a photovoltaic converter or any other object. The important characteristics of the incident solar energy are:
the spectral content of the incident light;
the radiant power density from the sun;
the angle at which the incident solar radiation strikes a photovoltaic module; and
the radiant energy from the sun throughout a year or day for a particular surface
The power factor of the inverter when it carries an inductive load or a capacitive load, usually the load power factor of the sine wave inverter is 0.7~0.9. #pure sine wave inverter 3000w If the power factor of the inverter is low, it is not only necessary to select a much larger load At the same time, #power inverter with charger it will also lead to an increase in the reactive current of the AC circuit, resulting in an increase in system losses and a decrease in system efficiency.
The efficiency of the inverter refers to the ratio of its output power to the input power under specified working conditions. Usually, the efficiency of a photovoltaic inverter refers to the efficiency measured when it is connected to an 80% resistive load. #inverter off grid Of course, the higher the efficiency, the better.
