Rated 5 out of 5 by from Great little generator Great little generator. Not sure what the reviewer above is talking about, it is 100% an inverter. It's very quiet compared to a normal generator, in eco mode it idles until there is additional draw placed on it. The listing on Home Depots website is a bit off, the true specs can be found on Firman's site. Overall very happy with this purchase.

Rated 1 out of 5 by from Unit is 120 volt only The unit may be perfectly fine, but the website listing is poor. Nowhere does it say that it is 120-volt only. There is a tiny little label on the control panel saying "not for 240V use", which does not even appear on the website photo. I didn't find out until I opened the box. The webmaster needs to be fired.

Rated 1 out of 5 by from False Advertising The generator is advertised as an inverter and it is NOT AN INVERTER - complete false advertising. As well as the DBs are not what is advertised - higher than advertised. If you want to buy a quiet generator don't waste your money on this one.

Does this inverter generator produce a pure sine wave AC? If not, is its AC output any cleaner than the non-inverter Firman portable generators? I can't find any data on this. Thanks, Marcus

Asked by: Marcus
inverter allows the generator to run just strong enough to power what is needed. This means it reduces how hard the generator needs to work. A non-inverter runs at full speed no matter what. Before I purchased this one, I googled on the company web site as well as "rate" and "review" this generator. Haven't used it yet as a secondary power during power outage, but have run some items as a test. So far happy

In the product over view it has this listed as a 223cc engine with a 6gallon tank that provides up to 23hours of run time? The bullet points below are claiming it has a 171cc engine an a 1.8gallon tank with up to 10hours of run time? I'm confused?

Just wondering how all of you are hooking this into your homes when you have a power failure? Quite a few people I know just shut the main house breaker off and plug this into an outside electrical receptacle. Just curious how everyone is doing this.

Asked by: Jeff1234
Hi, WE have many customers using a transfer switch to interconnect the generator to your main panel. You can also run an extension cord from the generator to your appliance. Please keep your unit 20 feet outside from any structure. Your friends at Firman

Using extensions cords to plug directly my appliances to the generator.  Because it is a floating neutral. Do I need to ground  the generator using a 8 feet ground rod?  Thanks.

Asked by: Peter
No, you can plug directly into your appliances.

The Firman Manual says the fb rating is 69db at 1/4 power, while, the Home Depot spec.s say 64db (no load rating). This is a significant difference. In fact 50% louder. A purchaser should be aware. -Thank You
