Direct answer
A generator is usually best for longer outages and high electrical loads, while battery backup is quieter, cleaner, and pairs well with solar. The right choice depends on outage risk, essential circuits, budget, fuel access, and whether solar integration matters.
Generators can support larger loads but need fuel, maintenance, ventilation, and safe transfer equipment.
Battery systems are quiet and low-maintenance, but capacity and runtime are limited by system size.
Hybrid solar-plus-battery systems can improve resilience during daytime outages.
