A few years ago, [Lukas Fässler] needed a solar charge controller and made his own, which he has been improving ever since. The design is now mature, and the High Efficiency MPPT Solar Charger is full ...

A German research group is trying to determine whether the combination of solar and storage with direct coupling and without the aid of maximum power point tracking (MPPT) electronics is feasible.

A maximum power point tracking (MPPT) controller circuit is extremely useful in solar photovoltaic systems for boosting power usage efficiency. The traditional MPPT design, though, requires the use of ...
