Grounding Lightning Protection

Lightning and related static discharge is the number one cause of sudden, unexpected failures in PV systems. Lightning does not have to strike directly to cause damage to sensitive electronic equipment, such as inverters, controls and radios. It can be miles away or not even visible, and still induce high voltage surges in wiring, especially, long lines. Fortunately, almost all cases of lightning damage can be prevented by proper system grounding. Our own customers have reported damage to...

Info

Disadvantage is inaccuracy due to the copper wire changing resistance as it heats or cools. The information on the Copper Wire Shunt Table is correct for copper wire at 68 F. (20 C.). For copper wire at 32 F. (0 C.), this method will yield amperage measurements that are low by about 10 . At a wire temperature of 122 F. (50 C.), this method yields amperage measurements that are high by 10 . If you compensate for the temperature, this technique can be made more accurate. pieces of nonstraight...

Charging Batteries Can Be A

In an article in Home Power 4, I discussed a working Wind PV system. There have been numerous requests for additional information on the Hydrogen Gas disposal system that I made to vent my lead acid battery pack. So here's how to make your own venting system out of off the shelf materials. And here's how it works Gerald Ames's battery pack complete with venting system Before explaining how the system is put together, some background on Hydrogen gas is necessary to understand where it comes from...

As an engineer, I am amazed to see how few people understand their light switches in our totally electric society. It is my experience that 100 of the people I have seen using gas generators GIVE UP and connect to their public utility. Editor's Note I don't know about 100 , Donald. We've seen quite a few folks start out with gas generators who've moved to PVs as prime power source. The generator fades quietly (the only time it's quiet is when it's NOT running)...

Editors Note Thanks for the flowers and the help, both are appreciated. How about it folks, anyone out there have more info on using hydrogen-oxygen generators to store energy Just received my first issue of HOME POWER, Right on I am a HAM radio operator and very involved in emergency communications, and as such, very interested in alternative energy sources, so will be looking to your magazine for information and resources. I am now using a 30 watt panel (cut in half and hinged to fold up and...

Using PVs to Pump Deep Wells

What can we do when the water lies deep down the well and all we have for power is sunshine Well, thanks to the folks at SolarJack and Kyocera, we can get along quite nicely. Read ahead and see how this family pumps their water from 400 feet down using sunshine. Eight Kyocera PV modules & the SolarJack pumps water The Situation Don & Carly White live on a mountainside near Jacksonville, Oregon. Their homestead requires a water system that could pump water from a deep well and do it...

Install A Proper Ground System

Standard practice on any electrical system is to drive a copper-plated steel rod (usually 8 ft. long) into the earth. This is a minimum procedure in an area where the earth is moist and hence more easily conducts electricity. The north side of a building, where the rain falls on the ground from the roof is a good place. Where ground is dry, especially sandy, or where the array is relatively large and high up, more rods should be installed, at least 10 feet apart. Connect all ground rods...

Type Lumens Per Watt

Fluorescent Standard 35-80 Miniature 50-70 High Efficiency 80-104 The above LUMENS PER WATT are for the lamp only with the exception of incandescent, the lamps require ballasts to control the power. Normal ac ballasts are only 50 to 80 efficient (using normal utility power). For PV applications the ballast function is provided by an inverter ballast with an efficiency of 90 to 98 . The higher frequencies (20-30,000 cycles per second), increase the light out of the lamp and allow economic design...

Linear Current Boosters

Several manufacturers are now marketing devices that promise to triple current output from a PV panel. These linear current boosters (LCBs) help eliminate the need for storage batteries or oversized arrays when running electric motors directly from the panels. Is this magic or simply alot of hype Actually it's neither. In keeping with Home Power's philosophy of delivering accurate and useful information on new renewable energy products, these devices were tested and their performance...
