Solar cell regulators

Victron Energy offers a wide selection of both MPPT and PWM controllers for solar chargers. See BlueSolar and SmartSolar MPPT Charge Controllers. In the name of the models, e.g. MPPT 75/50, the first number stands for the solar cell's maximum no-load voltage. The second number, 50, is the maximum charged current.
