High performance 24 and 48 volt systems for off grid cabins, sheds, trailers or anything....
Catalog is empty.
With the bigger systems, budget allocation is key, so we customize kits your project. Feel free to call 503-501-7733 to discuss.
At about 500 Watts, the poor performance and expense of 12 volt systems start to outweigh the convenience of standardized 12 V devices. The very maximum we can do 12 Volts is about 1500W per charge controller. The problem is that we need to use very big, expensive wire to move more than 500 Watts at 12 Volts, especially over a long distance. The easiest,cheapest, and most effective way to remedy this is by raising the system voltage. Voltage acts like water pressure, the more the better. It is much easier to push a large flow of water (AMPS) through large pipes (Wire) with HIGH PRESSURE (High Volts). High voltage is good and it becomes necessary at about 1300 Watts.
Possibly the greatest advantage is the cost savings. Raising the voltage means we can use a much smaller, less expensive charge controllers while increasing performance at the same time. When we move to 24 Volts, we double our charge controller capacity (cutting our controller costs in half). When we go to 48 Volts we quadruple our capacity (CUTTING CONTROLLER COST BY 75%!). A thoughtfully executed system can save you thousands.
Since having 12 volts available is a very nice thing, we use a simple and inexpensive converter so we can utilize 12 volt accessories.
Batteries and equipment are standardized to increments of 6 or 12 volts, so 6V, 12V, 24V, 36V and 48V. We need to keep this in mind when we size the battery bank. For example, if we wanted to use a 48 Volt system we would need 8- 6V or 4- 12V batteries.
