Backup power guides

Plan backup power for phones, a modem and router, laptops, radios, and other essential electronics using measured loads, runtime estimates, and safe fallbacks.

Learn a solar-sizing method for panels, battery energy, and inverter output using measured loads, seasonal solar data, system losses, and autonomy.

Compare portable power stations by usable energy, output, charging inputs, temperature, safety evidence, service, and a repeatable load test.

Plan a home battery backup without unsafe assembly shortcuts. Define loads, choose listed equipment, involve the local authority and a qualified installer, and document commissioning and shutdown.

Prepare backup power for winter outages with critical-load priorities, carbon monoxide safety, heat and water fallbacks, cold-weather limits, and drills.
