Charge Controllers

In solar energy systems, charge controllers are vital components that manage how power flows from solar panels to batteries. They oversee the charging and discharging of batteries to keep them functioning well and to extend their lifetimes. The simplest and least expensive type of charge controller is the PWM (Pulse Width Modulation) controller, which is used in smaller, less expensive systems. At the other end of the scale is the MPPT (Maximum Power Point Tracking) controller, which costs more but is found in larger, pricier systems.

Inserting a solar charge controller into a solar power system gives the user much better control over the power system itself and, most importantly, protects the chiefly vulnerable components (like the battery bank) from the power surges and other potential hazards associated with not having a controller in a solar power system. Modern solar charge controllers are also feature-rich, with many additional functions that serve to make the overall solar power system more reliable, which is, in many cases, an indispensable feature of a renewable energy setup. Overall, the charge controller is both a protection device and a reliability device.
