Can a solar generator run a refrigerator?
Often yes, but the answer depends on both running watts and startup surge. Check the refrigerator load against the inverter output and then estimate runtime from the battery capacity.
How much capacity do I need for overnight backup?
Add the watt-hours for the devices you need overnight, then allow for inverter losses and some margin. The runtime calculator is the safer starting point than a generic capacity rule.
Does solar input matter if I mostly charge from the wall?
Yes. Solar input becomes more important when outages repeat, run long, or limit access to wall charging. It determines how quickly the system can recover in usable daylight.
Is a portable power station the same as whole-home backup?
No. Portable systems can cover selected loads very well, but whole-home backup usually requires larger expandable systems, transfer equipment, and more deliberate circuit planning.
