Solar Controllers/ Solar Regulators

Solar regulators, which are also known as solar charge controllers, regulate the solar panel's charging current to provide the most effective charge to the batteries without overcharging them. They also prevent the batteries from backfeeding into the solar panel at night.

Pulse Width Modulation (PWM) regulators are the most effective means to achieve constant voltage battery charging by switching the solar system controller’s power devices. When in PWM regulation, the current from the solar array tapers according to the battery’s condition and recharging needs.

Maximum Power Point Tracker (MPPT) regulator / controllers can be used for additional daily production. They allow the solar panels to run at a voltage where they produce the most power (generally higher than battery voltage) and perform a voltage conversion to a level suitable for battery charging, with a higher charging current. They periodically sweep / track the optimum voltage level throughout the day to maintain the highest output.
