The ASC20W Controller uses less than 1/10th the power of the industry average.

The zero battery consumption at night saves lots of power, especially in systems that get covered in snow or need to last through prolonged overcast conditions.

Almost all other charge regulators have a standby current draw that will drain the battery during poor light conditions.
