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.

Shuts off and won't charge batteries

What does the unit do without the batteries attached? Try re-seating the connections.

Is this the same behavior as before you replaced the batteries? If so, the unit itself has likely failed and will need to be replaced.

Where is USB port

Many of my APC UPSes do not have a USB port. They either have a serial port or a 6-wire RJ-45 (or close to that size) port with a cable that has a USB jack on the other end.

I hope that this helps.

I am assuming that nothing is plugged in when powering up. This usually means that there is a short or damage to the unit. This forum discusses the issue:

UPS keeps beeping and resetting. I've swapped battery and getting same results ()

You have a brand new set of batteries with a bad UPS. Sorry to tell you that. You might have waited too long to replace your battery. What I mean, if you battery can not fully charge up, the inverter will try and keep charging it until it burns out. Then you buy a battery and you are now stuck with it.

You need a new UPS, may I suggest you get a bigger one....I have a 800VA with your name in it for only $80.00 plus shipping.

That is cheaper then what you are going to find. Keep it in mind also that APC is no a realy quality product either. Great marketing but poor support. Trust me that BE 500 is disposable.
