48 V DC power for regional telcos and TowerCos
Big enough that a site outage is a commercial problem, small enough that the OEM account team does not return the call quickly.
The pattern we see
Your installed base spans vendor eras — an Eltek plant here, an Emerson-labelled NetSure there, something Huawei from the last expansion. The labels say companies that have since been renamed or absorbed, the maintenance contract covers some of it, and the parts that fail are exactly the ones nobody can quote. Meanwhile every site visit to measure and top up a battery string costs a truck, a technician and a working window.
What this actually requires
- A single supplier who covers the whole mixed fleet rather than one vendor's slice of it.
- Documented compatibility per site, so a lithium migration is a controlled rollout instead of an experiment.
- A total-cost case built on avoided site visits, not on cycle life — because avoided visits are what the person signing understands.
- Someone who answers in your language at engineering level, including when the answer is 'not yet'.
How we approach it
Sites get ordered by installed base and battery age, not by billing history. An account with forty small sites is worth more attention than one with three large ones, because the migration compounds. From a documented pilot the expansion goes to five sites, then twenty, priced on cumulative volume rather than per order.
