Sun Xtender PVX‑340T Solar Battery - VRLA AGM Deep-cycle

The Sun Xtender PVX-340T is a premium valve-regulated lead acid AGM deep cycle battery engineered for off-grid and grid-tied solar and wind energy storage systems, delivering safe, reliable, and long-lasting renewable energy storage in the most compact and lightweight form factor in the Sun Xtender lineup — with zero exposed lead and 100% recyclable 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.
• 100% Recyclable and Environmentally Friendly — No Exposed Lead: The PVX-340T is designed with sustainability at its core — fully recyclable with no exposed lead, making it one of the most environmentally responsible deep cycle battery options available for solar applications.
• Ultra-Compact U1 Form Factor at Just 25 lbs — Lightest in the Sun Xtender Solar Lineup: The smallest and lightest battery in the Sun Xtender range, the PVX-340T delivers 34Ah of reliable deep cycle capacity in a form factor ideal for tight spaces, small solar systems, and portable or backup power applications.

The Sun Xtender PVX-340T 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-340T delivers that same proven platform in the most compact and accessible configuration in the entire lineup.

Designed for off-grid and grid-tied solar applications, the PVX-340T delivers 34Ah of nominal capacity at the 24-hour rate and up to 37Ah at the 100-hour rate. At just 25 lbs it is the lightest battery in the Sun Xtender solar range — easy to handle, position, and install in virtually any application where space and weight are primary constraints without sacrificing the proven Sun Xtender quality and reliability that installers have trusted since 1987.

Note that the PVX-340T uses M6 copper alloy threaded insert terminals rather than the M8 terminals found on larger Sun Xtender models. Silicon bronze bolts, nuts, and washers are included for installation. Shipping Hazmat Exempt, the PVX-340T is ready to deploy right out of the box.
