I get this particular comments quite often Zahn my other channels, so I don't really pay attention to losses this make sure that I'm overpowered if I did this the statements I say quite often that if people worry about efficiency they shouldn't be driving gasoline cars. This is true for me today as it was 30 years ago, I always want to build systems to get me where I need to be and right now configuring the systems and different configurations and yet bringing my bill down from $700 a month to around 200 is great for me and the system is not even done yet thank you for the comment look forward to more
I think you are reading the information wrong, that 29 volts is input from the power supply at 9 or 10 amps, which is 300 watts, not output because otherwise you should be charging at 580 watts, it seems to be putting out 12.6 volts at 20 amps to the battery, easily proved by using an amp meter to check the power in volts and amps going to the battery, so it is charging at 252 watts or around that based on ohms law which is what it is showing on the screen as to what it is charging the battery at. Your batteries are wired in parallel so it should be a 12 volt system which cannot take in 29 volts to charge by, you would need a 24 volt battery to charge around 26 to 30 volts otherwise you would fry the battery cells. The way my solar charge controllers work is it tells you the voltage and amps coming in and volts and amps going out. I can easily have 36 volts come in at anywhere from 1 to 20 amps and it puts out around 14.6 volts at anywhere from a few amps to the max rated amps around 30 to charge my 12 volt battery bank.
That’s what I was pretty much trying to say. He was reading it backwards. I don’t understand why people just can’t understand that free energy is not a thing. Well unless they are able to harness it at the quantum level but that’s like 1000s of years from now if at all. And I’m not talking about the woowoo stuff but the “zero point” energy that derives from quarks and subatomic particles blinking in and out of existence.
Your power factor is .6 i believe is what i saw. That’s the efficiency that you’re drawing from your plug. Ohms law man. So at 120v and 4.5 amps that gives you 540watt. So in a perfect system you should be getting that many watts of power from the grid and into you batteries. With your power factor of .61 that gives you 324 watts. 29volts at 19amp should give you 551 watts but you’re only seeing 245. So you’re missing 306 watts. So 245 watts divided by 29 volts means you should be using is 8.44 amps not 19. So lets find the difference in amperage. 19 minus 8.44 amps is 10.56 amps. 10.56x30 volts gives you 306 amps. That’s how much you’re losing due to inefficiency. You’re using 10.5 amps more than you should be to get those 245 watts. 551 at .6 leaves you 330. Which going back to you initial .6 of 120v x 4.5 amps plus or minus a few watts.
I just watched this and left a comment. The 29 volts, 29 v at 10 amps, is not going into the battery, it is the power being supplied by the chargers he has connected to the solar charge controller. It seems based on the display it is charging the battery at 12.6 volts at 19 to 20 amps which it shows charging the battery at 252 watts, taking in around 300 watts. So a loss of around 48 watts. The display gives all the info, the 29 volts is under the solar panel picture, 12.6 is under the battery picture, and the amps is the mppt charger converting the higher volts to higher amps to charge the battery by.
I see the DROK power supply is putting out about 270 watts, and the MPPT Charge controller is outputting about 250 watts so the charger is about 92.5% efficient. And the power supply is being fed by the inverter which is outputting about 350 watts. That makes the power supply about 80% efficient at that voltage. The inverter is outputting AC while the power supply and charger are outputting DC. You are misinterpreting how to use the numbers from the displays for your power calculations. That 19A on the MPPT display is for the output with the 12.7V which gives you the approx 250W. It's not part of the 30V.
That wasn't exactly the point of the video , And this is understandable we do these videos for classes that we hold and this reaches more people to see the point that we were making sorry about the confusion, What you couldn't have known is the question that we were asking. And that question is with this setup how is it possible that our energy bill is actually going down if we're losing power?
