1. Premium GEL Formula for Extended Cycle Durability

   Silica‑based gel electrolyte eliminates acid stratification and leakage risks. It boosts deep‑discharge cycle performance by 50% over conventional lead‑acid cells, well suited to frequent charge‑discharge cycles in solar power systems.

2. Ultra‑Wide Temperature Tolerance & Rugged Environmental Compatibility

   Operates stably from ‑40℃ to 65℃ with strong resistance to extreme heat, cold and vibration. Ideal for outdoor photovoltaic stations and remote off‑grid power projects under harsh climatic conditions.

3. Zero‑Maintenance Design & Reduced Long‑Term Costs

   Sealed valve‑regulated structure needs no water replenishment over its service life. Low self‑discharge retains stored power during long idle periods, lowering upkeep workload for isolated off‑grid sites.

4. Robust High‑Load Discharge for Continuous Energy Storage

   Large‑capacity design paired with low internal resistance minimizes voltage drop during heavy‑load discharge. It sustains steady operation of solar inverters and electrical loads to meet prolonged power demands of off‑grid setups.

5. Enhanced Safety with Flame‑Retardant Construction

   Acid‑leakage‑free design, flame‑retardant casing and integrated multi‑protection circuits improve outdoor operational safety, lowering hazards of fire risk and chemical corrosion.

• Solar off‑grid / grid‑connected energy storage systems and household photovoltaic storage
• Wind‑solar hybrid generation systems and independent power supply solutions for remote regions
• Small‑scale wind‑solar power stations and backup storage for telecommunication base stations
• Power supply for off‑grid equipment including outdoor monitoring systems, street lamps and mobile communication stations

• Charging: Compatible with solar charge controllers. Float charge: 13.5–13.8V; Equalizing charge: 14.4–14.8V. Prevent overcharging and undercharging.
• Discharging: Restrict daily discharge depth to ≤50% (max 80% to prolong lifespan). Full 100% discharge is strictly forbidden.
• Environment: Install in well‑ventilated, dry locations. Avoid direct sunlight and rain. Optimal operating temperature: 20–25℃. Apply thermal insulation or heat dissipation measures under extreme temperatures.
