Control Units
Specially designed charging control units for our powerful coreless generators.
To get 100% of generator’s performance out of the system and efficiently charge storage batteries, we have developed battery charging control units exclusively for our generators.
SKY-GB series
This controller enables quick charge control to ensure maximum power over a wide range of generator speeds, from low to high.
To take advantage of the light initial startup, which is one of the advantages of coreless generators, no load is applied at startup, and electrical conversion starts after the wind turbine rotation has increased. Of course, no assist function is required.
