Hm. In the past I have dragged along an APC 24 volt UPS hooked up to 
four of the batteries, but that will imbalance things.

Tripp-Lite makes a 36 volt inverter, but it is a bit pricey. However it 
will do anything you want and charge your batteries as well.

Another option is the Elec-trak inverter. I have one of these, it's kind 
of neat: It's a 36 volt motor coupled to a 120 volt AC generator. Big 
advantage is you will get a real pure sine wave from it. Problem is the 
frequency can vary a bit (although it runs pretty constantly). Also it's 
only 8a at 120 volts, which is enough to keep tripping the on-board 
breaker when you're using something like a chain saw.
