60 dB(A): how loud is it?

The manufacturer rates the AIVOLT VS12000411 11250W Dual Fuel Inverter at 60 dB(A), usually measured at 23 feet (7 m) and a light load. That is about the level of a conversation or a dishwasher: acceptable at a campground.

4

Outlets and home connection

Its panel offers 14-50R 50 A 120/240 V. The 14-50R outlet supplies 120/240 V, which is what a manual transfer switch or an interlock kit with a power inlet box connects to, installed by a licensed electrician. Never backfeed the house through a wall outlet.

5

Safety features and warranty

It starts with a remote key fob or the electric push-button, with a recoil cord as backup. A CO shutoff sensor stops the engine if carbon monoxide builds up around it; it does not replace distance (20 feet from the house) and CO alarms indoors. It is listed as CARB compliant, so it can be sold in California. The warranty runs 2 years (residential use).
