Xantrex XW Solar Charge Controller (XW SCC) is a solar charge controller that tracks the electrical maximum power point of a solar panel (Photovoltaic or PV) array to deliver the maximum available current for charging batteries. When charging, the XW SCC regulates battery voltage and output current based on the amount of energy available from the solar panel array and state-of-charge of the battery.

For example, the XW Solar Charge Controller can charge a 12-volt battery from a 36-volt array, providing flexibility for solar installers to use longer wiring runs without compromising efficiency.
