Comparing Solar Charge Controllers
Featured Product from PowerFilm, Inc.
Solar panels provide meaningful power at home, on the road, and anywhere you need it. A complete solar solution includes the panel, a storage device, which is usually a battery, and a charge controller to manage the relationship between the panel and the battery. What is often misunderstood or completely neglected is the vital role charge controllers play in the overall solar solution. Choosing the incorrect controller could mean reduced battery life, higher cost, or lower efficiency.
Today we are going to compare eight different charge controller technologies including direct charging, diode regulated charging, low drop out regulator charging, DC-DC converter charging, maximum power point tracking (MPPT), ratio power point tracking (RPPT), fixed set-point tracking (FPPT) and pulse width modulation (PWM) charging.
