Like apples and oranges, but I'll give it a try! Let's compare it with a 3000 Watt gasoline powered generator. First, the 3000 Watt generator is not rated for constant use, maybe 60% duty cycle, meaning that it can only produce 1800 Watts (3000 X .60=1800) continuous. Then we might consider elevation---where we are in New Mexico is over 6,000 feet. That reduces the generator power by about 25% more. Hmmm, we're down to 1350 Watts maximum (1800-450=1350) that it can produce continuously, with some ability to handle some short bursts above that.
Ok, let's say we run the generator for 4 hours a day. It should produce about 5400 Watt/Hrs. of total power (1350 Watts X4 Hrs.) That is approx. what the solar panels would produce in a normal day. BUT, the PowerGenX system has storage batteries that store enough power to provide up to 3000 Watt/Hrs. during the night (or a cloudy day).
Sooo, our unit produces about the same amount of power in a day that a 3000 Watt generator produces in 4 hours (no fuel, of course.) It (PowerGenX) can handle slightly larger peak surges and can spread that power over a longer period. For example, it can keep your refrigerator and freezer cool 24/7 (they don't run continuously) and take care of lighting, etc. at night as well. BUT, the generator uses about 2 gallons of gasoline and costs (at $4.00/gal.) $8.00 per day to run (and requires maintenance and doesn't last very long either---).
Hope this makes sense. I told you it was apples and oranges!
