It has scared the utility into behaving!

Bought this last year (2025) and it is comforting to know that it is there if I need it. For some reason the utility service has been good and we only had one power failure to test it. Worked very well. It is thunderstorm season now so I am hoping it will run for a few hours.

We Got PREPARED!

After SoCal Edison left us without power for 19 days in 2024 and had surges that destroyed our switch panel and side-by-side refrigerator / freezer we updated to the new 10 KW unit with all electronic panel and surge system and new UPS for our computer system. We also added a whole house insurance program and a service / monitoring system / account for our generator. So far we are very happy with our choice to upgrade our system.

Looks good and quieter then my portable generator.

We purchased ours a few months ago and had it installed about a month. We were going to use the existing switch we have with our solar panels and the EG4 batteries but come to figure out we had to get the switch installed by the company that installed our unit because the place to connect to the EG4 inverter was being used by one set of solar panels that was running on AC. If that set of solar panels was DC like my other set of solar panels then we could have used the EG4 inverter and saved a lot of money. Installation was done without any complaints and looks very nice. We only had the unit come on for a check so don't know how it will be when the power goes down which just happened a few days before the unit was installed. But our EG4 batteries did just fine. Don't know how much more to say except we are running it from a new 500 Gallon LPG tank they installed just for the generator.

Happy with everything, the Dealer, the product and the installation. However I feel like there could have been a better job restoring the landscape after digging a trench for the installation. They left it a muddy mess. Should have been packed down, raked, seeded with hay.

Portables are nice but whole house clearly better

We purchased a portable generator back in 1999 and used it several times throughout the years. But we are older now and the effort to maintain it and get it operational has become more challenging and so a whole-house "automatic" start generator made more sense.

A great Investment!

I purchased this 1 year ago and could not be more pleased. My wife and I both work from home. So, power outages which are becoming more frequent are disruptive. It's large enough to power our entire home. And the cutover is pretty seamless. We also have cellular backup for internet connectivity which is a super-solid combination.

I bought this a few weeks ago, already storms have gone through on two different occasions and knocked out our power. The generator has preformed flawlessly on both occasions, running for approximately 23 hours total for both occasions. My neighbors are jealous

Peace of mind

I bought this unit about a month ago, and so happy that I did. Within an hour of the install, we had an outage, and the generator kicked in within seconds. Being an elderly couple I wanted peace of mind that all systems, would function, appliances, well, heat and air everything is electric.

We've had it for a month, and I would have bought it way sooner had I realized how much comfort there is in just knowing it's there. We don't lose power here, but I DID stress every time they predict freezing rain, and we did fill buckets of water in the bathtub for toilet flushing every time they predicted bad weather. Now I can forget that stuff and just enjoy life. That's priceless.

Perfect for what we need.

Purchased a year and a half ago. Have had it kick in and run twice for about half a day each. As well as test running it has been very reliable! My wife and I are getting on in years and I have developed major health issues. Last major power outage was during Fiona and I was without electricity for a month. We have many medical items to assist us and are crucial. Was running for gas every day and waiting in line like everyone else, as well as trying to find open streets while the power crews tried to restore power. So finally said that this is enough and we are going to get a full house power unit and enough propane fuel to last a month. Feel the power situation isn't going to get any better soon.
