LARGE SYSTEM PROGRAMMING
In the fourth instalment of the rotating labs we teach the students how to program their solar electric system. Program, what do you mean program? Yes, I did mention in early posts that we keep our systems as “plug and play” as possible, but with all the different battery technology that is out there, we need to match our charge controllers (what controls the charge coming in from the batteries) and our battery charger/inverter (what we use to charge our batteries as a “back up” just incase there is a lot of cloudy weather or high usage) to our batteries.
When some hear the word “program” they get scared, but with the system we use and the modified manual that we use it is not hard at all. These devices have a lot of features that we would not use, so we shrunk the manual down to what we use in an off grid location. The students get to come in and step through the modified manual and get the chance to “push buttons” and set up the system to their choice of batteries. Currently we have four different types of batteries that are recommended, so there will be slight differences in how each one is programed. Once they complete this lab, they are more at ease and even though there may still be some apprehension, the students say “I can do this, with the manual of course”.
