Creating an Uninterruptible Power Supply From Your Solar PV System

Creating an Uninterruptible Power Supply From Your Solar PV System

“I have solar on my roof but when the power goes out, I’m out of luck!” Until recently, grid-tie inverters have been designed to perform only one function: to convert varying DC power from a solar array into an AC current source solely for the purpose of feeding into the grid to reduce your overall power bill. Since your power system will not be able to power up the whole grid, it must shut down when the grid is out – a...

Power Factor and Power Factor Correction

Power Factor and Power Factor Correction

Power factor (PF) is a topic that has been understood since the advent of electrical distribution, due in no small part to Faraday’s experiments and Maxwell’s subsequent mathematical expressions. It is defined as the ratio of real power flowing to the load to the apparent power in the circuit. When you hit the brakes in your car, you get a linear slowing effect. Operating at low power factor is a little like having the brakes...

It’s now been one year and nine months since my wife Nantzy and I bought back the Solar Living Center from the Colorado corporation that I sold to back in 2000.

I’m happy to report that the transformation is nearly complete!...
