Description
The Sun Xtender PVX-2120L is a maintenance-free, valve-regulated lead acid AGM deep cycle battery engineered for off-grid and grid-tied solar and wind energy storage systems, as well as uninterruptible power applications.
Key Features
- Pure Lead Calcium Grids with Thicker-Than-Industry-Standard Plates — Delivers longer cycle life, increased reliability, and greater power output compared to conventional deep cycle batteries.
- Proprietary PolyGuard® Microporous Polyethylene Separators — Provides dual-layer insulation protection for positive plates against shorting, shock, and vibration — a feature exclusive to Sun Xtender.
- Maintenance-Free VRLA-AGM Construction — Non-spillable design requires no water monitoring or replenishment ever and can be installed upright, on its end, or on its side for flexible placement.
- Heavy Duty Solid Copper L Blade Terminals — Corrosion-resistant solid copper blade terminals supplied with silicon bronze bolts, nuts, and washers, purpose-built for high-capacity solar and industrial installations.
- High-Impact Copolymer Polypropylene Case with Thick End Walls — Prevents bulging under charge pressure, delivering long-term structural integrity in demanding off-grid environments.
Since 1987, Sun Xtender has designed VRLA-AGM batteries purpose-built for renewable energy storage, making the PVX-2120L a proven choice for large-capacity solar battery banks requiring robust high-amperage performance.
The PVX-2120L ships Hazmat Exempt and includes two handles for safe handling of this high-capacity battery in the field.
With a 24-hour rate capacity of 212Ah and a 100-hour rate of 250Ah, the PVX-2120L is well suited for large off-grid solar installations requiring substantial energy reserves for multi-day autonomy without grid access.
