The Steca PR 1010 is a highlight in the excellent Steca range. The latest charging technologies, combined with a Steca-
AtonIC state of charge determination, result in optimal battery maintenance and control of the module output.

A large, easy-to-understand display provides information about all operating modes. Data such as voltage, current and
state of charge can also be displayed and the controller has an energy meter which can be reset by the user.

This controller is suitable for systems up to 900Wp and will work in 12V and 24V systems, up to 10A.
