Home Backup Power Options Explained

Battery systems are quiet and can switch quickly; solar can replenish them when conditions allow. Fuel generators can provide high output while fuel is available but add noise, exhaust and maintenance.

Backup systems trade capacity, power and replenishment

Hybrid systems combine technologies so one source covers another's weakness.

What to ask next

What is the claimed energy source? Where is the system boundary? What has actually been measured? Can an independent investigator reproduce the result? Those questions prevent terminology from substituting for evidence.
