Now let's compare the efficiency between MPPT controller and PWM controller;
This is the PWM controller, this is the MPPT controller;
We use a professional photovoltaic simulator;
We simulated 12 kilowatt photovoltaic panels, with 20PCS 600 watt photovoltaic panels;
The maximum power point of the photovoltaic panel is 420 volts, which is 10PCS in series and two parallels;
600-watt photovoltaic panels, 10pcs in series and two in parallels;
At this time we turn on the photovoltaic panel and the PWM controller starts charging;
For a 12 kilowatt photovoltaic panel, the maximum PWM output can only be 8 kilowatts;
Photovoltaic panels can only produce 8 kilowatts, and the power of photovoltaic panels can no longer increase;
Now let's test the MPPT controller;
first we pause the photovoltaic panels for a while.
Now we have switched the cable to the MPPT controller
Now we start charging the MPPT
MPPT is identifying the maximum power,
Its power has been increasing and is now almost 11 kilowatts
The photovoltaic panels already have output 11.8 kilowatts of power.
