Off Grid Solar – Xantrex

Date: March 9, 2012

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

The XW Solar Charge Controller can be used with 12, 24, 36, 48, and 60-volt DC battery off-grid-solar systems and is able to charge a lower nominal-voltage battery from a higher nominal-voltage array. For example, the XW Solar Charge Controller can charge a 12-volt battery from a 36-volt array. This provides flexibility for installers to use longer wiring runs without compromising efficiency. The XW Solar Charge Controller can be installed in single or multi-unit configurations with a Xantrex XW Hybrid Inverter/Charger or can be used in other stand alone solar systems or off-grid-solar systems where a solar charge controller is needed.
