It's me again.
I may have mentioned this in another thread. I ran across the idea of using a discarded UPS as a power inverter. The idea is that people often opt to replace a UPS rather than incurring the cost of new batteries. You use a car battery connected to the alternator on the vehicle with a circuit in between to keep from draining the battery under the hood.
Quoting the poster on another forum:
"We use a second 12v battery with a Schottky battery isolator hooked to our alternator, this allows the truck system to charge the second battery without discharging the truck engine battery. We then take an old UPS and use it as the inverter to run a portion of the electrics and 12v led lighting.
You can google ups as inverter to get some info on how to use the ups as an inverter. The isolator diodes are readily available, used in a lot of big car stereo setups.
This seems like overkill, but has proved handy to keep things running and lighting available during setup and changeovers, and its really not expensive, the UPS was free, the schottky diode and heat sink about $40 and a second 12V truck battery." (Generator/Inverter, staying powered up? Food Truck
I wanted to run this by you good people to see what you think. I plan to experiment with this soon if I can find an old UPS I think I still have or if my brother finds one at his work. I am looking on Craigslist as well. I will keep everyone updated as this progresses. I appreciate your insight.
