11,000 watts is still enough to power a small household with several household appliances running at the same. The beauty is that you do not have to fuss about anything because the technician installs everything for you, including the connection to the home’s LP supply so that you never have to worry about refueling.
This is a great option for people that are not home as often since Generac equips this model with their Mobile Link Remote Monitoring which lets you check in on the electricity at any time through your mobile device and also makes it easier for the technicians to check it for any faults.
