For a clinic in Port Harcourt, Obio-Akpor, Eleme or Bori, a power cut is not just a cost. It can be a risk to patients. Solar with lithium storage gives steady power.
Critical vs non-critical loads
We split the building into two circuits:
| Critical (always on) | Non-critical |
|---|---|
| Vaccine and drug fridges | Office ACs |
| Theatre and delivery room lights | Water heaters |
| Oxygen concentrators | Kitchen |
| Lab equipment | Staff quarters |
| Computers and records | Outdoor lighting |
The critical circuit runs on solar and batteries at all times.
No-break power
When the inverter powers the critical circuit all the time, there is no gap when NEPA goes. Equipment does not reboot.
Fridges for drugs and vaccines
They must stay cold day and night. We size the battery so they never go warm, even on cloudy days, with grid or generator top-up if needed.
Protection
Clinics need good earthing and surge protection. Read earthing and surge protection for solar.
