[RE-wrenches] Well pump with Sol-Ark

[frenergy]

Interesting the variation in experiences. Most of my jobs are off-grid 
these days which almost always means a (reliable) well pump need.  I'd 
entertain the idea of 3-phase with VFD but that's quite a bit more  
initial expense for this customer and possible higher long term costs 
with the VFD equipment?  Once again, the value of being transformer 
based (unlike the Sol-Ark) for surge.
