Alternatively, run your equipment on DC from an Iota DLS charger, which is constantly trickle charging some batteries. When the power goes out, it will run a lot longer because you're not converting (like a UPS) from DC coming out of your batteries to AC and then converting from AC back to DC again in a POE to power the radio.
Just use DC to DC converters to get the different DC voltages you need to run your various equipment. Plug your generator into the Iota charger to power it. I bet you'll get clean DC out of it. Especially if a battery is plugged in, which I think will help smooth out the DC current. I haven't tested it, but we're using DC everywhere. Just don't have to use a generator since the battery backup lasts so long. I recently had a tower with 6 radios on it, which had two deep cycle marine batteries from walmart. Someone somehow left the breaker off after working on the site. It ran for 3 days directly off the batteries before going down. We now have to monitor each the site is being fed by AC or not. Haven't got around to that yet. Maybe some mFi will help with this. Except the single port mFi doesn't have ethernet. Cheers!
