Compare sump-pump backup approaches, check the assumptions behind runtime claims, and make a test record for the pump, battery, alarm, and discharge path.
Backup power guides
Plan for a powered medical device outage with a care fallback, device record, manual and provider checks, backup power, relocation, utility contacts, and a safe restart.
Estimate battery-backup runtime from measured loads, usable capacity, reserve, conversion loss, output limits, motor surge, temperature, age, and a real test.
Compare lead-acid, AGM, lithium-ion, LiFePO4, and emerging battery options by complete-system use, maintenance, temperature, usable energy, and safety.
Choose a portable generator from critical loads, starting demand, a safe outdoor location, connection method, fuel plan, service, and the exact manual.
Compare battery stations, portable generators, solar-plus-storage, and standby systems by critical loads, outage duration, safe connection, and maintenance.
