1. High‑Performance Deep‑Cycle Design, Extended Service Life

   Adopts high‑tin alloy positive plates and robust active materials, offering 30% longer service life than ordinary lead‑acid batteries. It withstands repeated charge‑discharge cycles, perfectly matching the cyclic working mode of solar control and storage systems.

2. Broad Environmental Suitability & Outdoor Durability

   Operates reliably from -20℃ to 50℃, with strong tolerance to temperature fluctuations and vibration. Well‑suited for outdoor solar stations, off‑grid projects and unattended photovoltaic control environments.

3. Zero‑Maintenance Construction & Low Operational Burden

   Valve‑regulated sealed structure requires no water replenishment during its whole service life. Low self‑discharge preserves residual power during long idle periods, cutting maintenance work for remote solar sites.

4. Steady Power Output for Solar Control & Storage Demands

   Optimized internal structure and low internal resistance minimize voltage drop under cyclic loads. It ensures stable operation of solar controllers, inverters and supporting equipment to meet continuous power needs of solar systems.

5. High Safety & Stable Gas Recombination

   High gas recombination efficiency (≥98%) prevents gas buildup. Leak‑free sealed design improves safety for outdoor solar applications, avoiding acid leakage and corrosion risks.

• Standby and cyclic power supply for solar off‑grid/grid‑tied storage and solar control systems
• Energy storage for residential and commercial photovoltaic power generation projects
• Wind‑solar hybrid power systems and independent power supply in remote areas
• Power supply for solar street lights, outdoor monitoring equipment and small photovoltaic stations

• Charging: Matches mainstream solar charge controllers. Float charge: 13.5–13.8V; Equalizing charge: 14.4–14.8V. Avoid overcharging or undercharging.
• Discharging: Limit daily discharge depth ≤50% (max 80% to prolong lifespan). Complete 100% full discharge is strictly forbidden.
• Environment: Install in well‑ventilated, dry areas. Keep away from direct sunlight and rain. Optimal operating temperature: 20–25℃. Take heat‑dissipation measures in high‑temperature conditions.
