I recently got into Goal Zero products for emergency power backup. I have 4 power packs for a total of 1400 amps cabled together and 2 thirty amp solar panels which can be linked for quicker charging. The power packs utilize a 400 amp power inverter. They can be kept on charge 24/7 from household power, charged from a 12 volt source, or the solar panels. I also keep some of my essential radio equipment in a cardboard lined trash can serving as a Faraday Cage for EMT protection. These include a weather radio, a set of 35 mile FRS radios, small 7" tv, and power strips.
