Ordered from Norwall and was very pleased with customer service who provided advice throughout delivery and installation. The genset shipped very quickly, although actual delivery to the site was delayed by about a week due to the freight company's shuttling between a "hub" and "distribution center" and then back to the "hub" before they finally delivered.
Installed the genset myself and installed the transfer switch with the help of a licensed electrician (power company requirement). The installation went very smoothly and the integrated pad saved me time and money by not having to pour concrete. The electrician commented several times how impressed he was with the quality of the transfer switch and the entire setup.
The generator has functioned flawlessly during several power outages. It is so quiet that you may not know that it's in use unless you are outside near the genset or standing near the control panel.
I cannot comment about the web interface as there is no connection at this site.

I find this to be the most user friendly unit to install and program.

This is one of the finest generators on the market today for homeowners in the affordable range.

The generator is very quiet compared to others generators I have seen. It does the job it is intended to do. However the Ethernet port resets constantly causing the browser to not connect properly or lose connection while you are attempting to use the web interface. Sometimes you get weird looking pages et. The email setup is poor. For example the field “user name” is used for both logon and from email address. So if your server requires a login name that is different than the from address i.e. email@example.com the system will not work. Further it is plain smtp and not able to do any ssl or encryption on the net leaving the email ripe for hacking. Make sure you set up a special from email just for the generator. Also I am not happy with the way load shedding is designed. If I have 2 loads let’s say 2 Air Conditioner units on the load shedding if they both come on and usage is 95% it will shut both off and after 2 tries never turn them on again without manual intervention. It would be nice if you could have them cycle each load for a specific amount of time so one load would be on at a time as reasonably demanded.
I have heard there are issues with it and Windows 8 but I could not duplicate them
BTW I own one of the oldest microcomputer consulting firms in the USA

After Sandy I knew we needed a backup in the event of another storm. I was surprised at the number of trees that had fallen and the big job that had to be done by LIPA. This generator was hooked up as directed by a licensed electrician and plumber and they were amazed as I on how quiet and smooth running the generator is. We have lost electricity only once since it has been hooked up. Did not hear anything until I opened the window and saw it working beautifully. I would recommend this generator to everyone for its reliability and craftsmanship.
