Every unit in one tableThe full spec database
Add up the watts of what you will run times the hours, divide by 0.85 for the inverter, add 20% headroom, and check that the unit's continuous and surge output clear the largest device. The sizing page does the sum from sourced device draws; the job pages above are pre-set.
Match capacity to your devices and hours of use, then compare weight, recharge speed and price. Check motor-starting surge separately from running watts.
None is best across the board. At each size the brands trade price per watt-hour, output, weight, solar input and expandability against each other, which is why the picks are by job and size rather than by brand. The brands page and the brand-versus-brand pages show the ranges side by side.
Usually cheaper per watt-hour, and expandable units let you grow later. But capacity you carry and never use is weight and money, and a large unit refills more slowly from the same panel. Size to the job, then look one class up only if its price per Wh drops sharply.
It runs the loads that matter in an outage: a refrigerator, a router, medical devices, lights and phones, for as long as its capacity allows. It does not run central air, an electric range or a water heater. The home backup page sizes the realistic kit.
