...t; hence the UPS's preferred to remain on battery power. Recently, the power went out and fired up the generator. Surprisingly, all UPS worked and accepted the generator power. This time the only difference was that we also powered off some halogen spotlights and some energy saving compact flourescent lighting from the generator. Can anyone shed some light on what happened? When I get a chance, I will try and repeat what happened and see the outcome...

Hi, I'm the original poster on the subject. Thanks for all the replies. A few more points. The generator outputs 7kw @ 220V. The total PC's supplied is about 9. I estimate power consumption to be 9 x 300w=2700w 4 halogens @ 400w each=1600w 10 Compact Flourescents @ 11w =110w Therefore total power=4410w Which leaves me with spare capacity of about 2590w (in theory). I think its the halogen lamps that is helping "smooth" out the power. Previously, when I ran the generator, I did not have the halogen lamps on, and the UPS failed to recharge. R...
