A Post-Disaster Power Triage Kit for a Small Clinic: Load Definition, Photovoltaic and Battery Sizing, and Load-Shedding Rules

Design paper (SIMULATED, NOT MEASURED): defines a triage load set for a small clinic after a disaster (cold chain 0.96 kWh/day, oxygen concentrator and monitoring, LED lighting, communications, and household phone charging as a secondary load), sizes a 2.8 kW photovoltaic / 14.4 kWh battery kit serving the full 4.94 kWh/day load under 2.5 peak sun hours, gives state-of-charge load-shedding rules, and prints the failure case: a seven-day storm week ends at 7.6% charge with oxygen rationed on days 6-7, and a ninth storm day empties the battery. Kit cost USD 10,070, mass 360 kg.
