Excellent customer service. The rep even called back the next day to be sure I was getting the right size for my property and needs. I'm so grateful to the company. THANK YOU for an excellent support system and great service.
Perfect size to run the whole house and my water pump. Living in the country the power goes out alot. This generator provides power to the water supply for my large animals and heat in the house. WHEW! It's a blessing. Thank you
Impressed, struggled with battery, but once installed started with no problem, very satisifed!
Love the generator when itâ€™s working properly and running ., but the co2 sensor keeps shutting it off if the wind is blowing the exhaust right back at it and you know how wind can be. As long as you have the wind blowing it away works just fine
Great product and great customer service! We look forward to working with our rep again.
Thanks to Larry for working with me the order and delivery process. Very glad to finally have my generator - delayed due to global supply chain issues for several months. However as soon as the items came in my experience was fast and easy through to delivery.
I purchased two of these inverter generators 11 years ago. The first one has remote start. These generators were purchased to provide power during a hurricane outage. I pulled both gens out two weeks ago for Hurricane Laura. Both fired up and run perfect under loads. These are dependable generators. I only run non ethanol premium fuel in each. I replace the fuel with fresh fuel every year. The carbs are stored dry of fuel. I am on the third battery for each generator. I cannot store with the battery in the generator due to a parasitic drain that empties the batteries in less than two months. The two batteries are kept on a battery tender. Other than that, I highly recommend these generators especially if you have a low amperage 240 volt application.
I initially ordered a generator from another vendor, only to find out that it was out-of-stock and wasn't shipping.
My order at National Supply was processed and shipped the same day, and it arrived within the cross-country shipping window provided (1 week). My local driver assisted with a tailgate delivery and the contents arrived packed extremely well and in perfect condition.
Customer service, price, quality and timeliness of delivery. The packaging was PERFECT. Iâ€™ve honestly never seen better. The box was flawless. Generator looks very nice. Canâ€™t wait to use it. Highly recommend.
