PV On Vacation
What do you do when you go on vacation, and have a pet-sitter who just might decide to watch 19 straight hours of TV and leave a solar-powered light on non-stop for your pet? Plug these things back into the utility and power off the inverters. This doesn't leave much for the PV system to do. Only a small fraction of the available solar energy each day is used.
The charge controller for system #2 (bottom) did pretty much the
same thing every day. The system #1 charge controller, being somewhat
"smarter" sometimes did not bother with absorb stageor
had an absorb stage that was so short as-to not register on the monitor.
