- Iireyithingi ze-UPS ezikhoyo
- Existing generator ratings
- Generator control interfaces
- PV design or production simulation
- Transformer and switchboard information
- Required duration for each medical load class
- Site temperature and altitude
- Indoor or outdoor installation location
- Required testing and approval process
- Target commissioning date
Without these inputs, a supplier can quote 400kWh of equipment but cannot establish a measurable hospital-runtime obligation.
Define Hospital FAT and SAT Scenarios
The hospital should approve the operating scenarios before equipment production.
The FAT and SAT programme should include:
- Grid failure at the maximum critical load
- Loss of grid with no solar production
- Loss of grid during high solar production
- Generator delayed start
- Generator start failure
- Automatic load shedding
- Manual clinical override
- Low-SOC reserve protection
- BMS communication failure
- EMS communication failure
- Black start
- Controlled circuit restoration
- Grid reconnection
- Alarm and event recording
- Usable AC energy measurement
A simple battery charge-and-discharge test does not prove hospital resilience.
Sebenzisa i MegSolid BESS Factory Acceptance Test guide to translate the hospital operating sequence into measurable acceptance criteria.
Final Sizing Decision
The South African reference demonstrates that a 200kW AC solar array and 400kWh BESS can be combined to support an estimated 170kW hospital critical load.
It does not prove a universal 2.35-hour hospital backup guarantee.
The EPC must still establish:
- Which circuits cannot stop?
- Which circuits can tolerate a short transfer?
- Which circuits can be shed?
- How much usable AC energy must reach the hospital switchboard?
- Can solar restore the required SOC?
- What happens if the generator fails?
The correct procurement output is not simply “one 400kWh battery.”
It is a coordinated hospital microgrid specification covering the battery, PCS, UPS, solar system, generator, EMS, switchgear and acceptance tests.
