800 W is a ceiling within the route, not a compliance badge.

What 800 W means
The legal definition uses maximum rated AC output. Panel DC wattage, retailer naming and brief peak claims are different figures.
- Check maximum AC output
- Check the exact microinverter model
- Check final IPS evidence
- Check appropriate G98 evidence
What it can offset
An 800 W device can reduce live grid import up to its available generation and household demand; it does not reserve 800 W for one appliance.

Questions answered
Can it run an 800 W appliance directly?
It offsets total live household demand; it does not form an isolated 800 W appliance circuit.
Are 800 W panels required?
The relevant figures and limits cover the complete device; panel DC capacity and AC output are not interchangeable.
