Microprocessor for stacking inverters

AI Thread Summary
Stacking inverters to increase output from 800 watts to 1000 watts using microprocessors is discussed, with emphasis on the need for synchronization among inverters. A participant suggests that simply connecting microprocessors to consumer-type inverters may not work without significant modifications, which could be impractical. The discussion highlights the necessity of additional intelligence in inverters for proper synchronization, specifically mentioning grid tie inverters as a solution. Concerns are raised about the feasibility of reverse engineering existing inverters due to their fixed configurations. Ultimately, purchasing a larger inverter is recommended as a more straightforward solution.

Do you know if you could simply connect a few microprocessors to a few inverters to allow the inverters to stack with each other? If you can, can you help me figure out how to make this happen? Also, can you help me find a microprocessor for this task?

What do you mean by inverter? Is it some voltage supply. That you want to stack a few voltage supplies together to get some higher voltage. You want to put a micro-processor circuit at different voltage ( float on the supply voltage) to do better control at that point?

If so, I did so many of these, floating a micro controller up to 13KV or higher and do sophisticated control and data acquisition on top of high voltage.
 
Ok, sorry I didn't specify before. I wanted to stack inverters in a way that I can get 1000 watts of AC energy from my energy source, instead of only just 800watts, which is what my inverters can give at maximum at this point. I want to use the microprocessors to clock the AC currents that the inverters are giving out, so the inverters could sync with each other to provide one flow of AC energy.

I know that I can just buy a bigger inverter, but for this project, I don't want to
 
Hello elinxie - If you are referring to a 800W Consumer type inverter - no this will not work per se - you would need to hack each of them, not worth the effort. 1000W is not much - you can just buy a 1000W inverter.

The inverter needs some additional intelligence - to sense the other source and sync to it - this is known as a Grid Tie inverter, compare the pricing. Chances are you would not be able to reverse engineer the 800W inverter fully, they have been configured to operate a certain way - and inevitably your controller will conflict with the inverter controls - the result would be... interesting but not effective.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
