UPS sizing & installation
Load measured, autonomy agreed, unit sized properly — then installed with the bypass and the downstream distribution done right.
Service 03 · Onduleurs & supervision
When the grid blinks, nothing stops.
Uninterruptible power and live supervision for sites that cannot afford a gap. UPS installation, monitoring sensors, automation-network configuration and alerting that reaches you before a fault becomes an outage.
Scope
What the service covers.
Everything below is inside the quoted figure unless the quote says otherwise.
Power-quality conditioning
Sags, surges and frequency drift filtered before they reach the equipment that dislikes them.
Monitoring sensors
Temperature, humidity, door contacts, leak detection and current sensing where the risk actually sits.
Automation network
A dedicated, segmented network for the UPS, sensors and controllers, so supervision traffic never fights with the office.
Alerting & escalation
Thresholds set with you, alerts by email, and a clear rule for what counts as urgent at 3 a.m.
Dashboards
One page showing load, battery health, autonomy and environment — readable by someone who is not an electrician.
Deliverables
What you receive.
- Load and runtime study before any unit is proposed
- UPS, batteries and distribution installed and labelled
- Sensors placed, addressed and verified against a known reference
- Automation network configured and documented, with credentials handed over
- Alert thresholds and recipients agreed in writing
- Simulated mains failure demonstrated at handover
Indicative
Projects start from3 000 €
A single-rack UPS with sensors and alerting starts around 3 000 €. Multi-rack, higher autonomy or multi-site supervision is quoted per project.
- Site visit and written quote — no charge
- Fixed price once the scope is signed
- Commissioning and documentation included

Sequence
How the project runs.
Durations are typical rather than contractual — hardware lead times and site access are the two things that move them. Whatever the schedule turns out to be, you get it in writing before we start.
Written scheduleAgreed shutdowns
- Day 0Load study
We measure the real load and the critical list, then agree the autonomy the site actually needs.
- Day 1–3Sizing & quote
Unit, battery configuration, sensor plan and network design, priced as one package.
- Week 1–3Supply
UPS and sensors ordered; delivery dates confirmed before the works are scheduled.
- On siteInstallation
UPS, bypass, distribution and sensors installed; network segment configured and secured.
- HandoverFailure test
Mains pulled on purpose. We watch the transfer, the alerts and the runtime together.
Questions
Before you ask.
Usually less than people expect for a clean shutdown, and more than they expect for riding through short cuts. We measure the load first, then price two or three runtime options so the trade-off between battery cost and cover is yours to make.
Only if you want to be. Thresholds and escalation rules are set with you: what is informational, what waits until morning and what is a phone-in-the-night event. It is written into the handover pack.
Yes — it is the most common case. We survey what is already there, insert the UPS and the sensors around the existing distribution, and keep the changes to the live parts of the system inside an agreed window.
No. The supervision segment is yours. We configure it, hand over every credential and document what talks to what. Remote access is only enabled if you ask for it, and on your terms.
A single-rack installation: load study, one UPS with its distribution, a small set of sensors, the network configuration and the alerting, including installation and the failure test at handover.
