Sun Xtender PVX-12150HT 2V 1215Ah Solar Battery - VRLA AGM Deep-cycle

The Sun Xtender PVX-12150HT is the flagship model of the entire Sun Xtender battery lineup and the highest-capacity battery Concorde manufactures. A 2-volt valve-regulated lead-acid (VRLA) AGM deep-cycle cell built on the industry-standard Group L16 platform, the PVX-12150HT delivers 1,215Ah at the 24-hour rate — the highest per-cell capacity in the Sun Xtender range — in the tallest and most energy-dense standard battery form factor used in stationary solar applications.

As a sealed AGM design, the PVX-12150HT is the only VRLA-AGM L16 2V cell available from any manufacturer, replacing conventional flooded 2V L16 stationary cells with a fully sealed, maintenance-free, any-orientation design that eliminates watering schedules, acid spills, terminal corrosion, and forced ventilation requirements in a single substitution.

 Purpose-built for the most demanding stationary applications — commercial and utility-scale off-grid and grid-tied solar, telecom central office and long-haul backup, SCADA and RTU infrastructure, island power, and any installation where maximum per-cell energy density in the L16 footprint is the design goal.

Key Features:

• Flagship Model — Highest Capacity in the Sun Xtender Lineup — Delivers 1,215Ah at the 24-hour rate and 1,329Ah at the 100-hour rate per cell — the most energy-dense battery Concorde manufactures, and the only VRLA-AGM L16 2V cell available from any manufacturer; scales in series strings of 6, 12, or 24 cells to 12V, 24V, or 48V at full capacity
• 4 M8 Terminals for Flexible Bank Wiring — Four copper alloy M8 threaded insert terminals enable flexible inter-cell bussing in large series, parallel, or series-parallel bank configurations; all terminals supplied with silicon bronze bolts, nuts, and washers; optional factory-installed SAE automotive post terminal available
• Pure Lead Calcium Grid Construction — Plates are thicker than industry standard for longer cycle life, increased reliability, and greater power output; low impedance AGM design allows excellent charge acceptance with no current limit required when using controlled voltage charging
• PolyGuard® Microporous Polyethylene Separators — Proprietary dual-layer insulation protection shields positive plates against shorting, shock, and vibration; a Sun Xtender exclusive feature not offered by any other manufacturer in the industry
• Non-Spillable VRLA-AGM Design — Replaces Flooded L16 Cells — Valve-regulated, maintenance-free construction means no water replenishment ever; non-spillable design allows installation in any orientation without risk of electrolyte leakage, enabling safe installation in enclosed battery cabinets without the forced ventilation and acid containment infrastructure required by conventional flooded 2V L16 cells
• High-Impact Copolymer Polypropylene Enclosure — Battery cover and container uniquely molded with reinforced copolymer polypropylene featuring thick end walls to prevent bulging under pressure; built to withstand the demands of rugged commercial, industrial, and utility-scale stationary energy storage environments
• Hazmat Exempt Shipping — All Sun Xtender batteries ship Hazmat Exempt, simplifying logistics for distributors, dealers, and end users across all shipping channels

The PVX-12150HT delivers 1,215Ah of nominal capacity at the 24-hour rate and scales up to 1,329Ah at the 100-hour rate — the highest capacity ratings of any battery in the Sun Xtender lineup by a significant margin. At the 1-hour rate the battery delivers 798Ah per cell, confirming its ability to supply very high current for shorter duration loads in large inverter, UPS, and commercial backup power systems. The low impedance AGM construction ensures excellent charge acceptance across the full range of charge rates with no current limit required when using a properly regulated charge source — a critical advantage in large commercial and utility-scale solar and wind systems where charge current varies significantly throughout the day.

Sun Xtender's proprietary PolyGuard® separator system provides a level of plate protection not available from competing AGM battery manufacturers, directly contributing to the PVX-12150HT's long cycle life and resistance to vibration and shock loads common in commercial, industrial, and utility-scale stationary installations. The PVX-12150HT shares its L16 case dimensions with the 6-volt PVX-4050HT, and as a 2-volt cell it delivers far greater per-cell capacity while enabling precise bank voltage configuration through series string assembly — 6 cells yield 12V, 12 cells yield 24V, and 24 cells yield 48V, each at the full 1,215Ah cell capacity. Two integrated rope lifting handles facilitate safe two-person handling and positioning of the 124 lb unit during installation. All Sun Xtender batteries ship Hazmat Exempt, eliminating the regulatory complexity and additional freight costs associated with non-exempt lead-acid battery shipments.
