Telecom Energy Storage System(TESS)

GSL ENERGY supplies telecom energy storage systems for communication towers, base stations and network equipment. A lithium battery for telecom base stations should be selected from the site DC supply, equipment load and required backup duration. For telecom tower battery backup, review usable battery energy, discharge current, recharge time and environmental conditions together with the existing rectifier or power system.

For operators, system integrators and distributors evaluating a telecom battery supplier, provide the power-system voltage, target backup time, rack or cabinet dimensions and monitoring requirements. GSL ENERGY can review rack-mounted telecom battery and modular storage configurations, along with communication interfaces, approved expansion options and OEM/ODM requirements for the project.
