Storage Series
LONGWAY Storage series batteries(S Type, "s"behind the model name stands for Storage energy application).by combining the newly develop namo gel electrolyte with high density paste. LONGWAY create offers high recharge efficiency at very low charge current which is very common at renewable energy systems. The acid stratification is highly depressed by adding of gel. This range battery is highly suitable for the energy storage for renewable energy such as PV and wind turbine power systems.
General Features
12 years design life at floating conditions
Long life expectancy of 5 years at renewable energy system
Wide temperature range from -20 to 60C
Nano gel electrolyte eliminate the acid stratification and prolong cycle life
Round trip efficiency as high as 85%
Thick positive flat design with high Tin Low Ca alloy and high density paste
Low self-discharge rate and long shelf life (1 year at 25C)
Excellent deep discharge recovery capacity
Applications
Photovoltaic system
