1. Advanced GEL Technology, Long Cycle Life

   Silica gel electrolyte prevents stratification and acid leakage. Compared with standard lead-acid batteries, its deep discharge cycle life is increased by 50%, perfectly adapting to frequent charge-discharge cycles in solar systems.

2. Wide Temperature Stability & Excellent Environmental Adaptability

   Operating temperature range of -40~65℃, with high resistance to extreme temperatures and vibration. Ideal for outdoor photovoltaic power stations and harsh off-grid projects in remote areas.

3. Maintenance-Free & Low Operating Cost

   Valve-regulated sealed design requires no water topping-up throughout its lifespan. Low self-discharge rate maintains high charge even during long-term idle periods, reducing maintenance difficulty in off-grid scenarios.

4. Stable Heavy-Load Discharge for Energy Storage Needs

   Large capacity and low internal resistance ensure minimal voltage drop during discharge, supporting continuous operation of solar inverters and loads to meet the long-duration power supply demands of off-grid systems.

5. High Safety & Flame-Retardant Protection

   No risk of acid leakage. Flame-retardant housing and built-in multi-protection circuits enhance safety in outdoor applications, reducing fire and corrosion risks.

• Solar off-grid / grid-tied energy storage systems, residential photovoltaic storage
