El Wire AC inverter

El wire is cool and all but all the circuits that come with them are so half assed made it isn't funny. I have yet to get a circuit that is up to spec's that even closely adheres to any of the soldering tips and ticks, good soldering joints, anything. crap crap.  i have the components but the board is whack. how do you go about making a AC inverter for Elwire?

DC --> AC Inverter Question

I just bought a 12vDC to 115AC power inverter. But it will shutoff when the voltage drops below 10v :/ Can I disable this? It's annoying as I'm running it outside of a car so I cant just start an engine to charge the thing.

Variable DC input to a clean AC out put

So here is what I am trying to accomplish. I am trying to take an old Jacobs wind turbine controller that was designed for a grid tie application and make it off grid. There is a 3 phase "wild" ac input from the turbine that is rectifyed but not clipped by the internal SCR's to variable DC (40-180 volts). The sensing was designed to tie to the grid and power sync'd to line power and freq then exported or imported depending on demand. What I would like to do is build a Variable Dc input inverter that will put out a pure sine wave 120/240 vac split phase. Thus imprinting a usable power out put and allowing the cap/choke inverter to do its part. The design need not handle much power as it is only used as an imprint to regulate the power through the controller. If anyone had any idea on a build for this or a manufacturer that is producing such an item I could really use some ideas. Thanks

what will happen if i give dc 12v and 5 ampere to 2000watt inverter , how much ac ampere should it produce ?? Answered

I now what inverter does it convert dc to ac , i also know that it can convert dc 12 volt to ac 120 -110 volt but  the thing from which i m confused with is that what will happen to the ampere for example i have a 12 volt 5 ampere battery if i plugged the battery to 2000 watt inverter should it produce 2000 ac watt with just 12 volt and 5 ampere battery or i have to give more dc ampere to the inverter................ means can inverter    convert dc less volt to ac high volt  and  with also convert dc less ampere to ac high ampere   or will it convert  dc low volt to ac high volt without changing the dc low ampere and need more dc ampere or will it convert dc low volt to ac high volt with decreasing the dc ampere....

Running a fog machine and LEDs from battery pack

So I have this idea that will require a fog machine, some LED's, and a switch to turn them both on at the same time. The mechanical issues I have figured out, I just need a little help with the electronics. I plan to have this rig be mobile, as in backpack mounted, and I have no problem carrying a 12 volt battery on my back to accomplish this task. I need help on the specific electronics required in order to rig it together. To the best of my understanding, I need a 12 volt battery, an inverter/power outlet, and POSSIBLY a microcontroller, but I'd like to avoid the later at all costs, haha. Fog machine I intend to use would be 400 watt since it seems to be the most viable. If I can swing a KW one that would be awesome. And the LEDs would be either red or blue. I'd like a switch in the set up to allow for the fog/LEDs to be activated at the same time. URL to machine below: http://www.walmart.com/ip/Fog-Machine-400w/12335927 What I really need to know is how to set up the 12v to accept the 400w fog machine, if it's possible, and what type of gauge wire/cooling systems I would need if I chose to run this on my back for safety. And if you could help with the logistics of recharging the battery, that would be sweet as well. Thanks!

How to power speakers with batteries without an inverter?

I have a powered speaker system that runs on 120 AC. I have the battery and the inverter but I know the speaker functions on DC and it has an built-in AC-DC inverter. So to use my battery, converting it to AC with an inverter and then the speaker converting it back to DC and all this process will result in a lot of loss of energy and cost me in terms of runtime.  I would like to know if there is a way of by-passing the built in inverter and connecting the battery directly to the speaker without causing harm? What I thought was using a multimeter, measuring the voltage and the amper output of the built-in adapter and buying a battery with the same numbers and connecting it directly there. What are the risks in there? because I don´t want to burn my speaker.

Grid tie solar inverter power from a fixed voltage source?

Hello there! We have a 4Kw solar system installed at our home. We also happen to have 2 seperate circuits (ie 2 electricity meters). Annoyingly the solar panels are installed on the circuit that we don't use much electricity off so most of the generated electricity flows into the grid and (I know it's selfish) we don't benifit from it at all. There happens to be one lonely socket next to the solar inverter that is powered off the other electricity circuit and I'm fairly sure that the two circuits are on different phases. This is what I wanted to do and I was hoping someone might be able to validate this: I install a 240v AC to 24v DC converter (PAK650-24) and then an inverter to convert this back to 240v AC to supply that lonely socket where we need the power. Our solar inverter has a clever power detecter that switches a relay when production goes above 1Kw so I would connect this circuit to that relay. I also wanted to use a solar grid tie inverter from ebay because they seem most reasonably priced. They do however have a MPPT algorithm which is where I am not sure how it would react to a voltage source. Might anybody be able to tell me whether it would be fine to do this and most importantly about fixed voltage sources and solar grid tie inverters (which aren't really meant for fixed v sources). Many thanks, James

most simple and smallest way to charge a 6kV capacitor?

Hi again, I need some ideas on what type of DC-DC or DC-AC converter I can use to convert 9V into 6kV. the 9V will be a standard 9V battery. The output current doesn't need to be high. It's for charging a 6kV capacitor, and this May take a few seconds. It doesn't need to be charged in a few milliseconds. My own suggestions are these: - DC-DC booster (switching a coil to get high voltage spikes) but these only generate 200V max I think - DC-AC inverter like those small CCFL inverter circuits - Flyback - not compact enough - booster or inverter connected to a marx generator - but also not compact enough - ... any other ideas? It also doesn't matter if the output is AC or DC, I'll just add a HV diode to rectify it. Although, that also takes some space and it has to be Really compact. I know that converting 9V into 6kV might not sound like a simple thing, at least if I want to do it in one stage, but I've seen videos where people convert the voltage from a 1.5V battery into 4inch sparks. (that was with a marx generator too though).

Why won't a flywheel with a 12V DC motor producing 11V for 30 seconds run through a DC to AC inverter that requires 10V?

I am doing a science fair project that involves a solar panel, connected to a charge controller, connected to a 12V battery, connected to a switch system that can either go to a flywheel with a 12V DC motor or straight to a DC to AC inverter which leads to light standard light bulbs. The system worked (light bulbs lit) when I connected the panel to the controller to the battery to the inverter. However, when I had the battery power the flywheel and then have the flywheel output its energy to the inverter, the inverter shut down and would not work (red alarm went off). The flywheel is producing more than 10V (starts at about 11V) for at least 30 seconds, and the inverter's low voltage shut down in 10.5 plus or minus 5 volts. So why doesn't it work? Is the inverter messed up or is the flywheel outputing AC power? Also, when I connected the solar panel to the charge controller to the flywheel, the charge controller completely shut off. Are charge controllers not able to be directly linked to motors? And if I tried to directly connect the solar panel (which has 20V) to the flywheel (with a 12V motor), without a charge controller in between, what would happen?
