Good read!
Individual PV systems and environmental conditions vary almost as much as each user’s expectations of their personal system
Do you have the MS adaptor that fits into the data port of your Sunsaver 15?
It's low cost and a nice thing to have laying around
PM - me if you want to borrow mine
My rig is put away for the winter
MSVIEW can be used to log a few dozen parameters of that nice little controller
KJINTF:
, yes I have the MS adapter and SW. In fact I used the adapter and SW to make a custom charging profile for the controller that I can switch over to when it fits.
Didn't really think about using the SW for collecting the data Good and Bad.
The Good is that w/o the SW I used commonly available tools and techniques that others could use to do similar measurements on their systems.
Bad is that with the SW it may have been quicker and let me output charts and graphs. And by using the SW I likely would have been able to get data that would give a better shot at determining controller efficiency.
It would be interesting with the SW to watch input voltage/current with big changes in conditions (quickly shading one panel) to actually graph how the controller searches for Vmp and Imp.
Ah.... now a few more experiments I can think of doing....
