The MEP-002a was the primary backup for my house, I also have a MEP701a which will of course not run as much, though I am not using it yet, as we bought a motorhome about 4 years ago which has an onboard 4000 watt gas generator, so we are living in the RV in the drive way for now. Water is back operational here, though there is a boil order in place and the water is cloudy with sediment in it today. If the power is not back on in a day or two I will switch to the MEP701 as I also have about 75 gallons of diesel on hand, so far it has just been easier to run the motorhome generator and cords to the house for the chest freezer and refrigerator since the motorhome had a full tank of fuel when I put it up in its shed on the family ranch after our last trip. Thankfully it survived some of the other barns and tractor sheds did not, two of which were just rebuilt a year ago after being hit by a small tornado the week of Memorial Day 2019.. The ranch manager for the family ranch is using the MEP-016D and at the moment no one is using the MEP-003a, of course it sucks down the most fuel per hour of the bunch. I also have a Kohler 30ROZJ installed at my elderly mothers house, where my son, step sister and one of her sons are staying on the ranch
