Questions & Answers


Does it come with transfer switch

Asked by John September 13, 2020

how do you know what size generator will be needed?

Asked by sothrnyank August 10, 2020

What size generator needed? First figure how many watts or amps you need during your power out situation. Then buy a generator with greater watts / amps rating than what you need. Add up the watts / amps of the appliances you will want to run during the power out.

This unit is much quieter than the previous generation...Here is how I know: I purchased the previous generation Briggs and Stratton Genset (Labeled GE) with transfer switch from a Briggs and Stratton Dealer/Installer. The Purchase included full installation and came with a 5 year warranty. After 5 years and 30 days the unit began to "exercise" then started making a rattling sound. I ran out, turned the unit off within seconds and called the installer. The dealer/installer came and removed the unit after speaking with B&S after finding metal shavings in the unit...B&S asked the dealer if it was an "over-speed" that caused the engine damage and requested an engine tear-down. According to the dealer B&S required that the dealer tear down the unit. (To determine if it was an "over-speed"). The dealer reports that he did so and says he sent pictures to B&S showing the damage. The dealer said that B&S would replace the unit with this new model and that I would end up paying some of the labor(Tear down and Install). After 3+ months the new unit was installed and my cost was $1,200.00. I expected to pay something, but not nearly 1/2 the cost of this new genset. Apparently "Overspeed" is caused when the governor does not function....clearly a B&S issue and sounds like one they had much experience with. Engine failure 30 days out of warranty is troubling considering that this unit saw very light duty (-50? hrs.) and was maintained... I don't believe that B&S trusts their units, any more than I do. I was told that these new units have an electronic governor...maybe it is trustworthy? The dealer says that B&S has the best warranty coverage of any of the residential genset companies. Yes, I got something, but I hope others are treated better. I will update this review should matters change.
