Higher output/multiple EL inverter and wiring

by darksunrise957 on Wed Nov 27, 2019 4:25 am

Hello, I'm working on a project that will require just under 200cm2 combined (4 panels, different sizes) of EL panel, but the only inverters I see here support up to 100cm2. There's also a secondary (MUCH less demanding) EL wire section I was already planning on running off a separate inverter for control simplicity. This would mean I'd need 3 inverters running off the same battery.

Would there be any issues with running all three off the same power supply? And/Or is there a specific way to wire it (parallel, series, resistors, etc.)? Would it be possible to modify a single 12V inverter to run 200cm2 at full brightness? I'm assuming you couldn't give me a link to a supplier of a higher power one (this being the Adafruit forums and all), but I already need some stuff from here, so I would be fine using the three inverter plan.

Final question: I intend on controlling it through an arduino switching the current on/off BEFORE the inverter, to avoid the no-load issues, and whatever may come with controlling AC currents. Most likely using a mosfet or relay, though I'm not familiar enough with it to do it off the top of my head. Is there a proper/specific way to wire it?

Thanks very much; I need all the help I can get with this :)

There is no problem running multiple inverters from the same battery - as long as the battery is capable of delivering sufficient current.

For switching them on and off, a Darlington array is the most compact solution for multiple channels; https://www.adafruit.com/product/970
But MOSFETs are much more efficient power-wise.: https://www.adafruit.com/product/355
Wiring would be the same as for LED strips as in the 3-channel RGB example shown here: https://learn.adafruit.com/rgb-led-strips/usage

There are higher-capacity inverters out there. I don't have any experience with them, but there are several sites online specializing in EL wire, tape and panels that carry them.

Whoops, missed your reply. Thank you for your help. I'll keep this in mind.
