Nickel iron batteries are a powerful technology for lighting, charging electronics, and running small appliances, such as fans. Especially when “daylight drive” systems are used to power heavy loads like refrigerators and motors, a relatively small battery set can go a long way. (See “What is daylight drive?” for more information.)
Our Cabin kit is appropriate appropriate for lighting a one or two room cabin, charging small electronics like a phone or tablet, or running a DC fan to keep you cool in the summer. Laptops vary in their power demand. Some older, heavier laptops may need to be charged during the day with our Cabin Kit.
A Small House kit can charge a wider variety of larger electronics, like older laptops, batteries for cordless tools, or a host of equipment made for the 12 volt camping/ sailing/ RV market. Our Small House kit offers twice as much capacity as the Cabin Kit for lighting, and can light several rooms in a small house.
The Homestead kit has the potential to provide lighting, charging, and more for than entire household, especially when coupled with a daylight drive solar electric system. This is the size system that our community of twelve people have been using daily for the past 10 years, through winters and long cloudy stretches, without once running out of power.
A big advantage of our systems is that they are tenacious, while teaching energy conservation. ny other solar lighting kit on the market can be damaged if over-used, or turn off when you need it most in cloudy weather. With our nickel-iron based solar kits, if you have cloudy weather, the worst case scenario is that you may have to cut back on usage. Under no circumstances will the kit simply turn off like an overloaded inverter, or over-drained lithium battery. You will of course have better performance if you turn the lights off when not in use, and pay attention to how much energy you are using. Particularly with the smaller systems, simply paying attention to the timing of your energy use will allow you to do most of what you want to do most of the time, even with a modest kit. If the voltage falls below 10.5, you can reduce loads on the system, and the system will not turn off.
