The AL13 Power Tower product line is the best choice for the budget-conscious buyer. They are also easy to assemble on site with readily available professional tools, although larger sizes may need a small crane. We provide them in stacks of 2-8 1-meter high modules. All power towers have aluminum blades stacked alternately at 90 degree angles. This gives superior harvesting of wind from all directions and they therefore start at even lower speeds than our Tulips. They have the same internal aerodynamic advances and bouquet effect when grouped as our Tulips. We can also offer stacks of 3, 5, and 7 on special request (not in online packages) when there are height requirements, but we believe that most customers will want balanced stacking in multiples of 2. All groups of 4 or more require an external pole to attach to the top with an extra set of bearings.
 
For all off-grid projects, tell us after you purchase about the voltage and chemistry of thee battery you intend to use.
 
These beautiful wind turbines are around 3 meters. Blades are 2 meters high and 1.7 meter in diameter.They come with a generator rated at 500-1000 watts, a charge controller, a battery, and a 5-kilowatt inverter. Manufactured in the United States. Can go on exceptionally strong flat roofs (check with your civil engineer) or on the ground on a concrete base.
 
 
5 is the minimum we recommend with a 5-kilowatt inverter. 10 would be ideal. To add turbines to the package of 5, go to https://www.flowerturbines.com/product-page/2m-al13-power-tower-off-grid and add the number you want to add to the group.
