Yes, and for most domestic properties a battery is the cleaner and more practical solution.
Why a battery is usually better for homes: - Silent operation - Automatic switchover - No fuel storage - No emissions - Very low maintenance - Useful every day for savings, not just during outages
Where generators fall short — They are noisy, need fuel, usually need manual starting, and only become useful when the power is already off. They also do nothing for your energy costs the rest of the year.
Why batteries offer better value — A battery backup system can store solar generation, charge on cheap overnight tariffs, and reduce grid purchases all year round. Backup protection is only one part of the value.
When a generator might still be considered — Usually only where there are very unusual load requirements or exceptionally long-duration resilience demands beyond what a domestic battery setup is designed to cover.
For most Scottish homes, battery backup is the more practical long-term answer.
