Yamaha Motor Corp. introduces the EF6300iSDE generator that was created for quiet home back-up power. Designed as a home standby model, the EF6300iSDE has dual 120/240 volt output and is powerful enough to run most residential well pumps. Additionally, it can power a freezer chest and electric water heater for more than 10.5 hours, depending on load, on one tank of gas, making it a practical tool for anyone subjected to possible power outages due to ice storms, hurricanes, tornadoes and other infrastructure failures.
