Charge Controllers


The main function of a controller or regulator is to fully charge a battery without permitting overcharge or reverse current flow at night. If a solar array is connected to lead-acid batteries with no overcharge protection, battery life will be compromised.

 Charge controllers come in various types. Solar charge controllers regulate the charge from a solar panel array to a battery bank. Solar lighting controllers allow you to control DC lights while simultaneously charging a battery bank from solar panels. AC charge controllers allow you to charge your battery bank from an AC source (e.g.household current). Diversion load controllers are often used with wind turbines and microhydro systems to regulate battery charging. altE also offers some unique DC voltage regulators for original DIY projects. Be sure to add in the appropriate temperature sensor for you charge controller for optimal performance!
