Introduction: Transforming a 300W Sinewave DC/AC Mini Inverter to a 5000W Monster
I was planning to build a PIC microcontroller sinewave inverter and while browsing the internet to buy the necessary items I got accross this little 300w ready made pure sinewave inverter which would cost less than all the main items I was searching.
An idea flashed in my head to try to drive my "already have" square wave inverter's power stage from this ready made thing so I went ahead and ordered it.
After receiving the item I ran some tests on it and was surprised of the many hidden options this tiny thing packed:
-Built-in PWM maintaing a stable 230v at all times.
-Over voltage "+15v" and under voltage "+11v" cutoff.
-Low battery audibale warning.
-Waveform distortion :<5%
Actually 300w is way too much to drive the power stage, 100w would have been more than enough and the price would be much less but unfortunately I didn't find one.
Anyway.. The idea was a 100% success, I connected the mini inverter to my power stage that I already have built from a previous instructable and the monster came to life just as was expected :)
Of course you can adjust the power stage to your needs following the table of my main instructable.
We have a be nice policy.
Please be positive and constructive.
are you still helping on this project, I don't see any more replying to people's question for couple years
the same questions are being repeated over and over again, i've answered all of them and many times too.. people just don't like to read, they prefer to ask instead. That's the main reason of why I don't reply anymore.
