The challenge
Uptime is the entire business — Tier III and IV facilities demand N+1 redundancy and zero dropped loads — yet the traditional VRLA UPS string is a depreciating cost centre. It lasts three to five years, takes a large slice of the electrical room, and does nothing but wait.
Meanwhile AI and HPC racks are pushing power density and total demand up sharply, increasing both demand-charge exposure and the wait for grid-connection upgrades. The UPS asset should be doing more.
Where storage pays off in Data Centers
Lithium UPS / ride-through
Longer hold-up in roughly half the footprint, with 10–15 year life — far fewer replacements than VRLA over the facility's life.
Genset bridging
Hold the critical load instantly and cleanly while standby generators start and synchronise — no gap, no flicker.
Peak-shaving & grid services
Put the asset to work between outages: trim demand peaks and offer demand response or capacity where the grid pays for it.
Grid-connection deferral
Shave the new peak from AI/HPC build-outs to defer or avoid a costly utility upgrade.
What a Hanum deployment looks like
Lithium racks integrate with the UPS or static-transfer-switch bus in the electrical room, or a containerised system sits outside for grid-services duty. The system is sized to your ride-through window plus a peak-shaving buffer, in an N+1 arrangement.
| Topology | N+1 on the UPS / STS bus |
| Footprint | ~50% of an equivalent VRLA string |
| Service life | 10–15 years |
| Extra duty | Demand response / peak-shave |
Outcomes you can expect
- ~50% smaller electrical-room footprint than VRLA
- Lower lifecycle cost — far fewer battery replacements
- New revenue from demand response and capacity markets
- Deferred grid upgrades for AI/HPC expansion
At a glance
Common questions for Data Centers
Yes — the system is configured for the redundancy your tier and audit require, integrated with your existing UPS, STS and genset arrangement rather than replacing the whole topology.
Either. It can sit inline as the energy store for an online UPS, or act as instant bridging to generators. We match the architecture to your current design and availability target.
Yes. Grid-services participation is firewalled below your reserve floor — the system never dispatches energy that's earmarked for ride-through, so availability is never compromised.
Recommended systems
Data centers typically deploy the Container 5000 for grid-services duty, integrated with the in-room UPS for ride-through.
