Fr. Robert Ballecer, SJ as we all know sometimes we just got to "have POWER", so I was wondering if an arduino can be used to build a UPS, sine wave inverter charger, DC sourced generator such as solar, wind, etc? In my unfortunate situation insurance gives me 2 new (100 AH or so) gel pack 12V deepcycle batteries which I keep the ones being replaced (since, why not?) I've used a pair "wired in parallel" to hack and beef up a small UPS running medical equipment during power outages, thankfully (since the UPS used 14 gauge wires and needed around 3k watts) so we got our hands on a whole home generator. The generator is nice but that time it takes to kick on and the flickering of power still is a big issue so I would like to build on a budget a UPS for my whole private suite that has it's own 100A breaker box powered off the main building breaker box that the back up generator is connected to, and I would like to run the second box on a UPS to protect the electronics and medical equipment from power flicker and for the time till the generator turns on. Since I would also like to eventually put up some solar and wind power it gets a little more complicated requiring controllers an so on with cost starting to go up. I recently had someone said to me that it could be done with components and use an arduino as the controller and drastically cut the cost down. So can arduinos control POWER to and from breakers or at least individual outlets to have a large UPS which might be good for me since, hey free batteries ideal for indoor use right? With the right batteries being free what kind of cost could I save using an arduino and components vs MPPT controller and other equipment? What can an arduino really be unleashed to do?
