[RE-wrenches] Battery EQ question, Xantrex XW system (Dan Fink)

[Hilton Dier III]

Dan,

What Alan said.

The most important client is the one you turn away. The fact that the 
previous installer "fled" and that the client refuses to use a generator 
makes an alarm go "ah-OOO-gah! ah-OOO-gah!" in the back of my head.

I just walked away from a client after five years of repairing their 
boneheaded mistakes.* I should have seen them coming on the way in. 
Having repeatedly beaten their system into a quivering heap for years 
they are now "disappointed" with its performance and refused to pay my 
last invoice. I was there for them on short notice, on weekends, gave 
them sympathy discounts, the works. They think I'm a bad guy. 
Conclusion: There are some people who are too mechanically incompetent 
for off grid living. You cannot make them happy.

Say, "I'm sorry, but if you won't use a generator or pay for a 
maintenance contract, I can't help you." Really, walk away. "Gorgeous" 
and "so close" are the cheese in the trap.

And yes, a psychology degree would serve any of us better than an EE 
degree 99% of the time.

Good luck,

Hilton

* Client: "The system wasn't holding a charge when we had three toasters 
and two coffee makers going, so I added four batteries on the end of the 
pack." Me: "Um, your system is 48 volts - eight six-volt batteries. 
Adding four batteries makes it a 72 volt battery pack. Your system can't 
charge that high, so that's why it died." Client: "But there are four 
more batteries. That's another 50%." Me: "Remember how I've asked you to 
call me before you do stuff? Let's go through this again..."
