1500w inverter applications | Toyota Sienna Forum
Adding a large inverter to the base Sienna is impractical. Pretty much, you have to run off the 12 volt battery which is smaller than a non-hybrid battery. It takes 10 amps plus to get 120 watts. The battery will not be able to supply that for long. In addition, the inverter that charges the 12 volt battery is smaller than a non-hybrid alternator.
