The problem
Remote sites punish heavy, short-life batteries
Telecom sites need dependable runtime, face heat and frequent grid failures, and are costly to visit. Heavy lead-acid banks need space, ventilation and regular replacement.
48 V and 51.2 V packs
PB480100 and the 51.2 V range suit 48 V-class telecom DC systems.
Compact and light
More energy per rack unit and far less weight to haul to rooftop and hilltop sites.
Long cycle life
Handles frequent grid outages without the rapid wear of lead-acid.
Visible status
On-unit SOC and voltage display for quick site checks.
Sizing
48 V DC backup sizing
Worked out with a single stated assumption, so you can check the numbers yourself.
Estimates assume 80% usable energy from the rated capacity. Inverter losses, temperature and load profile change real runtime — our engineers size every system before quoting.
