Definition claim verification: Verified August 20, 2026

In plain language

When a proposal mentions Residential backup power, identify the exact equipment, configuration, and included work instead of assuming the label describes the whole system.

What it is not

It is not an automatic feature of every grid-connected solar or battery system.

Decision context

Why it matters

Supported loads, starting power, stored energy, solar recharge, transfer equipment, reserve settings, outage duration, fuel or grid availability, and operating rules determine service.
