I was wondering if using an mppt charge controller on a windblue 540 low wind pma would increase the power output that is going to the battery.
Here is my theory:
We all know that Mppt charge controllers converts the excess voltage (VOC) coming from your solar/wind power to amps.
I have a windblue 540 low wind pma and the current output is so small.The most I see out of it is about 4amp. I realize thou that the Voltage at Open circuit (VOC) goes up to all 40volts most times.
So I am guessing that if the current at that time is about 4amp then the total wattage would be 40 x 4= 160. Running that through a mppt controller you would get about 13.8V at approx. 11 amps after the mppt does its conversion in micro seconds instead of getting 4 amp at 13.8V using a regular dump load controller.
Please tell me what you think. Could this actually work?
