Grid Tied Systems


Battery backup is an important component of many grid tied renewable energy systems. Sun Xtender® batteries provide essential reserve power in the event of a utility outage or natural disaster. Grid tied backup systems should be sized in order to provide the required days of autonomy for essential electrical loads. For more information on battery sizing, please refer to battery sizing.

Sun Xtender® Deep Cycle AGM renewable energy batteries are specifically designed for long life in grid tied systems. The positive grids in Sun Xtender® batteries are thicker than the competition's and are made from a proprietary pure lead-tin-calcium alloy with special grain refiners. These features improve corrosion resistance of the grid and give the battery excellent cycling capability and float life.

The most important features of a grid tied battery bank are reliability and low maintenance. Sun Xtender® batteries have been the premium AGM renewable energy battery on the market since 1987. Sun Xtender's® AGM design is the original Absorbent Glass Mat battery (AGM) technology adopted by U.S. and Foreign Militaries worldwide. All Sun Xtender® batteries are sealed and maintenance free which means no spilling or acid spray, no watering or electrolyte checks, and the option to operate upright, on the side or on the end. Sun Xtender® batteries are housed in shockproof, high impact reinforced cases that restrain from bulging. Sun Xtender's® battery terminals and terminal hardware are constructed with copper alloy, corrosion free materials for low impedance connections and maximum conductivity.

A wide variety of sizes and capacities in 2 Volt, 6 Volt and 12 Volt configurations are available, including many configurations and layouts which are exclusive to Sun Xtender®. For more information please refer to the battery specifications page.
