Open Source Charge Contoller Yahoo Group
This group is dedicated to developing an open source charge controller with maximum power point tracking (MPPT). A charge controller sits between a solar panel, wind turbine, etc and a battery pack and ensures that the two play well together. A charge controller with MPPT allows a power source to charge the batteries at maximum efficiency.
We are looking for help from both the hardware and software community to support this open source project.
