UPS Alternative

Keep a gas boiler running through outages: understand pure sine wave power, pump demand, battery runtime and the difference between voltage protection and backup.
Compare a conventional UPS with lithium battery storage for long home outages, including runtime, system sizing and when sensitive equipment still needs a UPS.
Keep your router and ONT powered during outages: check device requirements, provider backup and whether a mini-UPS, power station or home system fits.
