Gel deep-cycle for
hot-climate
solar duty.
Thixotropic gel electrolyte holds shape inside the cell. Tolerates ambient temperatures above 35°C without electrolyte stratification. Preferred chemistry for equatorial off-grid and inland tropical solar.
Gel electrolyte
Silica-thickened sulphuric acid stays in place. No stratification. Tolerates higher operating temperatures than AGM.
Hot climate proven
Designed for ambients above 35°C. Equatorial solar, tropical telecom shelters, inland Africa and South Asia installs.
Deep cycle
Thick positive plates and high-density paste. Sized for daily PV cycling without rapid capacity fade.
Multi-orientation
Sealed VRLA construction allows install in any orientation except inverted, with no maintenance.
Gel chemistry where AGM cooks. Hot climate has its own battery.
True gel construction. Fumed silica thickens the sulphuric acid into a stable gel — fundamentally different chemistry from AGM. The gel resists stratification at high temperatures, tolerates deeper discharge with no acid migration and recovers stronger from sulfation than AGM cycling chemistry. IEC 60896-21 and IEC 61427-1 verified.
