Yamaha Generator


Please be advised the Yamaha Generator Model EF2000iS does not generate enough start-up current which causes the unit to overload. The generator then puts out non-true Sine Wave power. Progressive Industries units are designed to operate only on True Sine Wave power.


For this reason, The Progressive Industries Warranty is hereby void if an EMS Unit is used in conjunction with a Yamaha Generator Model EF2000iS. Any damage sustained to the EMS unit are the sole responsibility of the customer.
