- 1Problem
Frequent micro-outages during OPD hours
Vaccine fridge tripping, examination lights flickering, and a UPS quote three sizes larger than the clinic actually needed.
- 2Diagnosis
On-site load audit, not a spec sheet
Engineer profiled the fridge inrush, LED panels, nebuliser and reception PC over a full working day. Real draw came in at 38% of the vendor's assumed load.
- 3Solution
Split design — clinical vs. comfort
Lithium UPS for the fridge and imaging cart. Tubular inverter for lights and fans. Two zones, one honest bill, everything labelled at the DB.
