Не вижу практического смысла в повышении напряжения до 120в, при таком преобразовании происходят потери и неизбежно снижается ток нагрузки. Если надо высокое напряжение для питания бытовой техники, для этого есть инвертор 12/24-220 с нормальным синусом. Мне кажется это баловство, но оно полезное в плане проектирования dc-dc преобразователей.
Maybe make another; 230v?
This days there are already mppt step up available in the matket. I have one. Im using to charge my ebike battery 72v
It was good video ,but GUYS PLEASE DONT DO LOW VOLTAGE HIGH CURENT SETUP ON YOUR SOLAR ARRAY, it is not beneficial in any means, avoid it if you can, you will need to spend much more on thicker wires, really only solar with that low of a voltage that I have see was 70W pannel in that case if you have 2 70W pannels you will probably not spend that much on hogh voltage battery and you can even use PWM controler becuase it would be prety efficient with around 15V from pannels to 12V battery
In your previous test with the boost comverter, the issue is not that the solar panel is not outputting enough power, it's that the boost converter is asking for too much power. Try to test it again but limit the output current to a low current at first and start ramping it up. At some point the solar panel will not be able to provide enough power and the voltage at the output collapes. If the battery wants 50A, and then the boost converter will try to provide that current at the set voltage, however, if the panels cannot keep up with the power demand, the panel voltage will drop, and the output voltage of the boost converter collapses. Another thing is that the previous boost converter has a low voltage disconnect, try to set that at the Vmp of the solar panel so when the panel voltage drops below it, it will oscillate the boost converter at that voltage and keep the output steady at whatever power the panel can provide. ❤
I think if you modified it a little by upgrading the Wire Guage in the converter and with beefier masfets, I think that would work, oh, and decrease the current while the battery almost reached full point
Just wondering, how could MPPTs reach so much efficiency in conversion compared to typical boost and buck converters, where most of them adapt to a synchronous design to minimize loses, what makes an MPPT so special in converting energy?
ive done extensive testing to see if can boost 12 volt of 72 volt for charging ,but due to limitions iof the device it can only output less than an 1amp
Interesting test! I'm just wondering if your panels can't deliver more than 8 amps and this converter doesn't have MPPT built in so if your budget allows I'd like to see your review of the WZ10020L converter
This channel is excellent. A solar boost converter is particularly useful right now with the price of copper being sky-high.
