+ | The goal of the open source [http://www.freechargecontroller.org Free Charge Controller] project is to design a charge controller with [http://en.wikipedia.org/wiki/MPPT maximum power point tracking (MPPT)]. Maximum power point tracking allows a solar panel, wind turbine, etc to achieve maximum efficiency and deliver maximum power to a load. In this case, a load can be a battery, inverter, or the grid. This is both an open source hardware and an open source software project. All documents and files are released for free under the terms of the Creative Commons Attribution-Share Alike license. With enough help, it is hoped that future versions will support different battery voltages, off-grid and grid-tied systems, as well as other power sources such as wind turbines, micro-hydro turbines, etc. If you'd like to help, please [http://groups.yahoo.com/group/charge-controller/ join our developer forum]. | ||

* LT3652: the "Linear Technology LT3652 - Power Tracking 2A Battery Charger for Solar Power" contains most of the electronics required for MPPT up to 2 A in a single IC (4.95V to 32V). With the LT3652, the installer hard-wires some fixed approximation of the maximum power voltage of the solar panels Vmp at 25'C, and (optionally) a temperature sensor on the solar panel used to give some fixed linear approximation of the change in Vmp with temperature.[http://www.linear.com/product/LT3652] via [http://electronics.stackexchange.com/questions/10647/parallel-charger-circuits]. | * LT3652: the "Linear Technology LT3652 - Power Tracking 2A Battery Charger for Solar Power" contains most of the electronics required for MPPT up to 2 A in a single IC (4.95V to 32V).
