Hilda Winkler <hildawinkler77@gmail.com>: Jul 21 03:15PM -0700 hi group, why won't a 1.0 hp wet/dry vacuum cleaner model 2010. 120v 60hz 5.5a. Work on a 4000w 110v DC - AC Power inverter ..??? |

As in ampere hours, can you measure the battery voltage when the load is connected ? |

Bearing in mind that at those levels, the battery will need to supply several hundred amps for the motor to run. |

"Peter W." <peterwieck33@gmail.com>: Jul 22 08:39AM -0700 Mpffff. One Horsepower = 746 watts. For now, let's ignore the starting surge. 746/110 = 6.78 Amps. That is the *AC* load for the motor when running. 746/12 = 62.2 amps from the battery to make that load. Now, consider the starting surge (typically six (6) times the running current). That battery would need to put out +/-373 amps for the start. This also ignores inverter losses (typically between 5 & 15% - 5% for a grid-tie type, 15% for most others). The inverter may be rated at 4,000 watts. There are very, very few conventional automotive-type lead-acid batteries that could sustain it. Peter Wieck Melrose Park, PA |
