1. Premium Deep‑Cycle Performance with Extended Lifespan

   Constructed with high‑tin alloy plates and high‑strength active materials, it achieves 30% longer service life than conventional lead‑acid batteries. It endures frequent charge‑discharge cycles, perfectly matching the continuous cyclic operation of large‑scale solar control and storage systems.

2. Reliable Environmental Adaptability for Outdoor Use

   Stable performance across -20℃ to 50℃, with strong resistance to temperature shifts and vibration. Well‑suited for outdoor photovoltaic stations, unattended solar control cabinets and harsh off‑grid power scenarios.

3. Sealed Zero‑Maintenance Design & Reduced Operating Costs

   Valve‑regulated fully sealed construction requires no water replenishment over its entire service life. Low self‑discharge retains stored power during long idle periods, lowering maintenance workload for remote solar sites.

4. Large‑Capacity Stable Discharge for Solar System Operation

   Optimized low‑internal‑resistance design minimizes voltage drop under heavy‑load cyclic discharge. It ensures steady running of solar controllers, inverters and supporting equipment to satisfy long‑duration power demands of high‑capacity solar storage systems.

5. High Safety & Efficient Gas Recombination

   Gas recombination efficiency reaches ≥98%, preventing internal gas accumulation. Leak‑free sealed structure eliminates acid leakage and corrosion risks, improving operational safety for outdoor solar applications.

• Energy storage and standby power for large‑scale solar off‑grid / grid‑tied systems and solar control equipment
• Power supply for commercial photovoltaic power stations and household high‑capacity solar storage systems
• Wind‑solar hybrid generation systems and independent power supply projects in remote regions
• Power support for solar street lights, outdoor monitoring systems and medium‑sized photovoltaic facilities

• Charging: Compatible with mainstream solar charge controllers. Float charge: 13.5–13.8V; Equalizing charge: 14.4–14.8V. Prevent overcharging and undercharging.
• Discharging: Restrict daily discharge depth ≤50% (max 80% to extend service life). Complete 100% full discharge is strictly forbidden.
• Environment: Install in well‑ventilated, dry areas. Avoid direct sunlight and rain exposure. Optimal operating temperature: 20–25℃. Implement heat‑dissipation measures under high‑temperature conditions
