Description
The Sun Xtender PVX-840T 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 replenishment ever and can be installed upright, on its end, or on its side for flexible placement.
- Low Impedance AGM Design — Allows excellent charge acceptance with no current limit required under controlled voltage charging, maximizing charging efficiency in solar applications.
- High-Impact Copolymer Polypropylene Case with Thick End Walls — Prevents bulging under charge pressure, with corrosion-resistant copper alloy M8 threaded insert terminals supplied with silicon bronze bolts, nuts, and washers.
Since 1987, Sun Xtender has designed VRLA-AGM batteries purpose-built for renewable energy storage, making the PVX-840T a proven choice for solar installers seeking dependable long-term off-grid battery performance.
The PVX-840T ships Hazmat Exempt and includes two rope lifting handles for safe handling, making it practical for field installation in remote off-grid locations.
With a 24-hour rate capacity of 84Ah and a 100-hour rate of 96Ah, the PVX-840T is well suited for solar systems that require sustained overnight or multi-day energy reserves without access to grid power.
