The Solar series is designed for frequent cyclic charge and discharge applications
under extreme environments. By combining the newly developed Nano Gel
electrolyte with high density paste, the Solar series offers high recharge efficiency
at very low charge current. The acid stratification is highly reduced by adding Nano
Gel. This series is suit for energy storage for renewable energies such as PV, wing
turbine power systems and CATV.
