The Carolinas sit in the direct path of Atlantic hurricane season. When the grid goes down for days — not hours — your preparation determines your outcome.
The Situation
A brief outage is an inconvenience. A four-day outage after a major storm is a crisis — spoiled food, no air conditioning in summer heat, security systems offline, sump pumps inactive, and no way to charge communication devices. Fortress designs systems specifically for extended outage scenarios, with fuel management and runtime planning built in from the start.
Generac and Kohler standby generators on natural gas or large-capacity propane tanks provide days or weeks of continuous runtime — not hours. Fortress sizes fuel storage for your specific extended-runtime requirements.
Generac, Kohler, Cummins
On-site propane storage designed for 72+ hour runtime. Automatic delivery coordination ensures your tank is full before storm season. Fuel quality monitoring and treatment prevents degradation during storage.
Above-ground propane, diesel storage systems
Battery systems activate the moment the grid fails — before the generator even starts. Critical loads like sump pumps, refrigeration, and communication devices never see an interruption.
Tesla Powerwall, Enphase, Franklin Electric
Power restoration after a major storm often comes with significant voltage spikes. Whole-home surge protection at the service entrance protects every appliance and electronic device when the grid comes back.

On natural gas, a standby generator can run indefinitely as long as the gas supply is maintained. On propane, runtime depends on tank size — Fortress designs storage for your specific requirements, typically 72 hours to 2 weeks.
Before. Generator installation typically takes 2–4 weeks from consultation to final inspection. Demand spikes dramatically after major storm events — lead times can stretch to months. The best time to install is before you need it.
Yes. A properly sized whole-home generator runs your entire HVAC system. Fortress performs a full load analysis to ensure your system handles your AC, refrigeration, and all other loads simultaneously.
Sump pumps are among the most critical loads during a storm — and they fail exactly when you need them most if the grid is down. A whole-home generator or battery system keeps your sump pump running throughout the event.
Yes. Fortress serves Charleston, Santee, and the Lake Marion region. We specify coastal-rated equipment designed for salt air environments and coordinate all Dominion Energy South Carolina permitting.
A complimentary power assessment gives you a complete storm-readiness plan — system sizing, fuel storage, runtime calculations, and installation timeline — before hurricane season demands it.
