The following document has been added at the bottom of the menu KD-Reports: “Manual of a 27.6 V, 200 W battery charge controller”. This manual describes a battery charge controller with a separate voltage controller and dump load. The dump load contains two 100 W resistors and a heavy Darlington transistor placed on an aluminium cooling plate size 3 * 250 * 500 mm. This battery charge controller can be used for 24 V battery charging windmills with a maximum power of 200 W. A larger dump load can be made if more 200 W modules are connected in parallel.
