UPS or generator?

Instead of using the 1.8 amps I rounded it up to 2 amps...thats 240 watts/va

figure about 70% efficiency for the ups.

240/12Volts = 20 Amps /.7 eff gets about a 28 amp draw on the batts

155 Ah /28 amps is about 5.5 hours

heres a link to a place to show the calcs

Forgot....It has batteries built into it also?

any idea the AH ratings of those?\

I had a power outage of approx. 12hours and my battery backup worked flawlessly. I was going out of town for a overnight trip and depended on my pellet stove for heat. Now try that with a generator! Yes, a auto generator would of done the same but the manual generator, no! Knowing the house is warm when I am at work is a big plus in the back of my mind. The generator is good when I am home and for extended outage.

I have two 6vlt batteries of 105 amps each. Trojan T105's

The run time with a decent deep charge battery would be at least a 1/2 day or more. I looked at built in transfer/charge/inverter units and decide against because of service. My previous one bite the bullet and was unserviceable. Using separate units, if one fails it could be replaced with another. I have no knowledge on the Triplite and cannot give feedback. I wouldn't worry to much on the power factor as long it stays running long enough to power up the gen.
