In Boston we have two EU2000i that can be put in parallel for 4,000 starting watts. We wanted something that used minimal fuel for a Hurricane Sandy scenario, with heavy snow. We have city water and gas heat, hot water, stove, oven and clothes dryer so we just needed to run the heat circulation pump and keep the fridge and freezer cold in cold weather.
Only problem is our new electrician absolutely positively would not buy off on the manual interlock switch we had to take the house off line. He installed a Reliance transfer switch. It is very easy and convenient: but requires 240v feed. Those Hondas and most other Inverter generators are 120v only.
We found three with 240: the fuel injected Honda EU7000iS, the Yamaha EF6300, and a newcomer: the Briggs & Stratton Q6500. Surge rating is 6,500, 5,000 watts continuous. 128 lbs, 5 gallon tank, and comes with wheels. Will run up to 14 hours on a tank (under low Load), and I知 sure folks will quickly have an adapter for a marine fuel tank to extend the run time. Like the Hondas it has an eco mode that increases rpm on demand. The big difference is price: the Honda is $4,000, the Yamaha is $3,300, and the Briggs is $1,500!
We lose power so seldom in Boston that it was worth any risk (as we still have the EU2000 and could run off cords). It was released last Spring s there arent too many reviews so far: but people who ran them for the hurricanes in the SE were almost all 5 Star.
Q65�� QuietPower Series Inverter Generator
At our place in NH we have a 220v well pump and outages are common enough (lots of heavy snow and trees) that we didn稚 mess around. We have a propane fueled 14KW Kohler with auto start and auto transfer switch. Longest we致e run it is 18 hours, knock wood.
FWIW Honda has a new, lower cost Inverter model, the EG2800.
The Briggs is designed for this kind of home backup, with a locking 30A plug
