Exactly. That's why I always have a load profile for each system on
file, and as soon as they're doing something different, we're off the
hook. It opens the door smoothly towards upgrading the system for their
new loads. And yes a new load profile, until they add even more in 5
years.

On these small projects, its very important to nail down the exact
load, to keep the pricing sane. I list on the estimate what the
system is designed to do; for instance 18 w load 24 hrs/ day.
Then if something goes wrong and they are running more than they
should you just gently point out that that was not what the system
was designed to do.
I learned a long time ago, that you can't take name plate power
draw numbers, or count on the manufacturer to provide those
numbers; you've got to confirm it with your own monitoring equipment.
