Re: ups does not work on home generator

As a Ups manufacturer, I suggest the following: check the output frequency of the generator, it shout be 60hz +/- .5hz

Re: ups does not work on home generator

Your generator is the problem, ups's usaully work from 90volts-125volts and the frequency needs to be steady, any lower or higher and it will not charge. it is a safety protocol with in the ups cpu.
I know of a voltage regulator for generators that would make the voltage consistant and even and that would cure your problem.
here is a example website:

How can you tell if the system is bad on apc back ups es 650

plug something (other then a computer)into it, turn the gadget on, then unplug the UPS. If the gadget continues active the UPS is OK. Generally after you have punched every button (circuit breakers). After that put a Volt/Ohm meter on the batteries (and the charging wires to check the charging curcuit is OK.

APC BACK-UPS ES 500VA fails to provide back up during power failure

Get APC Powerchute Personal Edition for free and run it. If it says your battery isnt charged, check its voltage disconnected. Charge it with a car battery charger and see if its still a good battery. If not , replace it. If the battery is good, then check the charging voltage. Should be about 14 volts. if not, check the small transformer on the main board. Should be 120 in and 17 to 18 out. 4 diodes in a bridge for charge. The input to the transf has small fuse into it alone.

Take off the bottom cover and make sure the battery is connected (both terminals).

Charging apc 800va through home generators

The reason of this is the UPS cannot adopt on the frequency that is being generated by your home generator. you should use APC smart ups series coz smart-up series can work on a wider input frequency range.

APC ES-350 won't turn on; all I see is a blinking light.

Try looking for a small circuit breaker on the side that says "press to reset" - you could have tripped it accidentally when you unplugged the iPod.  Also, try pressing and holding the UPS power switch for 10-15 seconds.  That should force a power on as well.
