Controller

The main function of a charge controller or regulator is to protect your battery from overcharge and block a reverse current. If a non-self-regulating solar array is connected to lead acid batteries with no overcharge protection, the life of your batteries will be compromised.

Simple controllers contain a transistor that shunt the PV charging circuit, terminating the charge at a pre-set high voltage and, once a pre-set reconnect is reached, opens the shunt, allowing charging to resume.

More sophisticated controllers utilize pulse width modulation (PWM) or maximum power point tracking (MPPT) to assure the battery is being fully charged.The first 70% to 80% of battery capacity is easily replaced, but the last 20% to 30% requires more attention and therefore more complexity.
