Solar Charge Controllers

For battery systems, solar charge controllers regulate the power going from the solar panels to the batteries. With a charge controller, batteries will not overcharge, leading to optimal battery life and performance.

Most charge controllers use pulse width modulation (PWM) to slowly lower the amount of power applied to the batteries as the batteries get closer and closer to fully charged. This type of controller can keep batteries in a fully charged state, or float, indefinitely. Some of our more popular PWM charge controllers are the Steca PR3030 charge controller and the Xantrex C40 charge controller.

The most recent and best type of solar charge controller is called maximum power point tracking or MPPT. MPPT controllers are able to convert excess voltage into amperage. This allows the voltage to remain at an opmimal level to reduce charge time. MPPT charge controllers result in lower power loss. One of our more popular MPPT solar charge controllers is the BZ MPPT500 charge controller.
