3 phase inverters [RE-wrenches]

[Todd Cory, Bald Mtn. Solar]

Perhaps we need a backup, backup generator. I am not sure why these 
things always fail when no one is around and when you (and the fish) 
really need them. I think there is a Murphy's rule that applies to this 
though.

So no one makes a 3 phase inverter? 3 SW units would be pretty spendy 
and way beyond the capacity needed. Being 3 phase is generally 
considered commercial, I suppose any inverter that is 3 phase would be 
huge capacity and extremely expensive.

Maybe I should look into changing out that motor to 208 V single phase 
after all.
