Thanks for the compliments Jim. I put allot of blood & treasure into helping all you guys learn the technology so that you can help me sell and support the systems. Yes, you are really getting the stuff down. Thank you for taking so much time to read all this stuff that I put out. It has made your training so much faster than most because you take a lot of time reading posts on the forum.

OK, Amps is a number usually used to think of a maximum load of a device. Watts we use more in renewable energy because it is used more in terms of actual AMOUNT of power.. more like volume of electricity.

To get Watts from Amps is pretty simple. Wattage ratings are usually listed in equipment manuals
or on nameplates. If your equipment is rated in amps, multiply that number times AC utility voltage to estimate watts. (Example: a refrigerator requires 4 amps. So, to get watts 4 amps × 120 volts = 480 watts.)

Like with most rules and calculations it goes backwards too. If you did not know the Amps of that refrigerator but you knew the Watts.. (Example: refrigerator is 480 watts. So, to get Amps 480 watts divided by 120 volts = 4 amps.)
