High frequency inverter versus low frequency inverter for solar panel. Which one produce more electricity? I think high frequency inverter produce less watt because the solar panel is arranged in series configuration. In theory the watt is the same and the voltage is increased. My growatt produce 80-150-600 watt from 9 x 140 Wp solar panel. What do you think? Is micro inverter/low frequency inverter is better?

Ice Cream or candy? Which produces the most weight gain?



If this is a DC-DC inverter, then the operating frequency really doesn't matter. For a given power level, the low frequency unit will require more 'iron' and therefore be bigger and heavier. It may be a bit cheaper though. Technology is pushing inverter frequencies higher and higher. A high freq inverter uses a smaller transformer and is therefore smaller and lighter. It *may* also be a bit more efficient.



If you are asking about an inverter with a DC input and a 60 Hz AC output, then things change a bit. A low frequency inverter may be referring to one that is just a 60 Hz oscillator and power amp. Or a simple 60 Hz oscillator outputting a square wave. The first suffers from high losses, and the second suffers from a poor output waveform.



A high frequency inverter here would likely produce the 60 Hz waveform via pulse width modulation - building the output waveform from higher frequency 'pieces'. This gives good efficiency and a much purer output waveform than a simple square wave oscillator.

Assuming the frequency applies to the internal DC/DC converter, a higher frequency will get more power through the transformer. So if the transformer is about the same size in each converter, you would get more output from a high frequency one.

Both answers infer more output from high frequency, but both use bad analysis. Ask again, if you get no more answers.

THAT IS A DUMB QUESTION WITHOUT KNOWING THE BASIC FACT OF TRANSFORMER CHARACTERISTIC. FREQUENCY HAS NO DIRECT RELATION TO POWER GENERATION ! FREQUENCY AFFECTS THE SIZE OF TRANSFORMER THAT IS USED. HIGH FREQUENCY 100KHz TRANSFORMER IS 100 TIMES SMALLER THAN A 60Hz TRANSFORMER ,AND IT PRODUCES THE SAME WATTAGE.
