I see many computer UPS out in the market, but do UPS meant for whole houses exist? I live in a small town, and we have brownouts often, lasting for a split second up to 20 seconds at a time. A lot of our electronics get messed up 'coz of this. We also have a back-up generator. Is there a way to connect the generator to the UPS so that if we get a blackout lasting for hours at a time, we have time to turn on the generator without power dying.
Yes, You can use of heavy powered commercial UPS for your whole Houses. But it's so Very expensive for using in the whole house. As you are asking, you can also connect Riello UPS products from your generator directly.
Sort of. Hospitals have combined battery and diesel generators that ensure there is no interruption in supply. Very expensive option though.
Critical commercial and government facilities, like hospitals and air traffic control centers, have power systems that combine back-up battery banks with generators (usually diesel powered) to provide continuous power. These systems are custom engineered for each facility. No doubt one could be built for a residential application, but it would be expensive.
