The Sun Xtender PVX-1080T is a premium valve-regulated lead acid AGM deep cycle battery engineered specifically for off-grid and grid-tied solar and wind energy storage systems as well as uninterruptible power for essential appliances and machines, delivering the highest capacity in the Group 31 Sun Xtender lineup with exceptional cycle life, superior charge acceptance, and proven non-spillable construction.

Key Features:

• Pure Lead Calcium Grid Construction with Thicker-Than-Industry-Standard Plates: Engineered with pure lead calcium grids and plates thicker than the industry standard, delivering longer cycle life, increased reliability, and superior power output compared to conventional AGM batteries.
• Proprietary PolyGuard Microporous Polyethylene Separators — Exclusive Dual Layer Protection: Sun Xtender's patented PolyGuard separators shield positive plates against shorting, shock, and vibration — a dual layer insulation protection feature not offered by any other manufacturer in the industry.
• Non-Spillable VRLA-AGM Construction — No Water Monitoring Required: The sealed valve-regulated AGM design eliminates the need to monitor and replenish water levels, delivering truly maintenance-free operation across the full service life of the battery.
• Low Impedance AGM Design for Excellent Charge Acceptance: The low impedance construction allows for superior charge acceptance with no current limit required during controlled voltage charging, maximizing solar energy harvest efficiency on every charge cycle.
• High Capacity Group 31 Platform — 108Ah at 24Hr Rate and 124Ah at 100Hr Rate: The highest-capacity battery in the Sun Xtender Group 31 range, delivering deep and sustained discharge performance for demanding solar, wind, and UPS applications where maximum energy reserve is critical.

The Sun Xtender PVX-1080T represents over three decades of innovation in renewable energy battery design. Since 1987, Sun Xtender — a division of Concorde Battery Corp — has been engineering VRLA-AGM batteries specifically for the demands of solar and wind energy storage, and the PVX-1080T stands as the top-capacity offering in the Group 31 platform — delivering 108Ah at the 24-hour rate and an impressive 124Ah at the 100-hour rate for applications that demand maximum energy density and reliability.

Built on the same proven platform as the PVX-890T but with significantly greater capacity, the PVX-1080T is the natural choice for larger off-grid systems, high-demand backup applications, and any installation where sustained, deep discharge performance over long periods is the primary requirement. Its two rope lifting handles and standard M8 threaded insert terminals with included silicon bronze hardware make installation straightforward despite its 65 lb maximum weight.

Shipping Hazmat Exempt, the PVX-1080T is ready to deploy with standard M8 threaded insert terminals, an optional factory-installed SAE automotive post, and a Group 31 industry reference classification — integrating cleanly into any solar storage system requiring maximum AGM capacity in a proven, industry-trusted form factor.
