Took LG washer off generator. Running off panels, no battery

Wow.

More details please?  I have a MSW inverter sitting on a shelf, forgotten since I got a pure-sine years ago.
Are you saying I can bolt "anything" the the H-bridge and get AC without also producing magic smoke? 
(Within reason?) 
(what's reasonable when doing this?)

OperaHouse:
Yup, this is the real story.  Find the high voltage capacitor, run wires out for  + and -, and run any voltage in up to 140V. I'd suggest using at least 24V because of the way they might be bootstrapping the high drive.

The control electronics still has to be powered.  The MSW inverter must have an on off switch, not momentary. Locate the side that doesn't go to the 12V terminal.  Supply 12V to that side and it will require around 50ma.  As long as that voltage stays in reason, the inverter will keep running. I ran a 50W 24V lamp on 20V.

This has possibilities. Many small AC motors are impedance  protected so they can be browned out a bit.  With a 60V array, you could use a boost transformer to get 120V and run 90-130V for example.  Still must be some considerations for turning it on and off at low voltage

OperaHouse:
I should note that this should work with all older MSW inverters with a common negative between input and output caps without microprocessors which have more sophisticated fault detection.  The one I used had another unique feature.  With a little under 120V DC I was getting a reading of 113V RMS.  When I added the extra 18V from the additional 12V panels, it went up to 119 RMS.  Immediately I thought those panels weren't producing.  There was nearly 160V DC with no load.  Apparently as part of the regulation the duty cycle reduces as voltage goes up.  I don't think this is common.
