Annual load bank testing that proves your UPS and battery strings will hold the load when the mains fails — in a controlled, low-risk environment.
A load bank test applies a controlled, resistive load to your UPS system and battery strings, simulating a real power outage without risking your critical load. It verifies that the UPS can deliver its rated capacity, confirms true battery runtime, and exposes ageing cells, weak connections and capacity shortfalls before they cause a failure in anger. We recommend an annual load bank test — carried out during a scheduled maintenance visit or as a standalone appointment — so you have documented proof that your power protection infrastructure actually performs.
We apply a stepped resistive load up to your UPS rating to prove it delivers its full kVA/kW capacity under stress.
A controlled discharge confirms the real autonomy of your battery strings — not the datasheet figure.
Load testing surfaces ageing cells, loose connections and capacity shortfalls before a live outage exposes them.
Testing runs in a managed environment, scheduled out of hours where needed to minimise risk to the load.
You receive a full test report with discharge curves, runtime figures and pass/fail evidence for compliance.
Year-on-year results let us trend capacity decline and plan battery replacement before runtime falls short.
We review your UPS rating, battery configuration and site logistics, and agree a test load and timing window.
Our engineers connect the load bank and apply a stepped resistive load, monitoring voltage, current and runtime throughout.
We analyse the discharge curve, compare actual runtime against design autonomy and document every result.
Where weaknesses are found we quote remediation — battery replacement, connection repairs or re-test — with no obligation.
Book an annual load bank test and get documented evidence your system will hold the load.
