I bought the Harbor Freight set of 4 25 watt panels this past winter and used them to run a maple sap vacuum pump. They worked well and did the job. I ran the pump off a small deep cycle battery and kept the charger on the battery all the time. during sap flow.
I am wondering about the off season. Is it OK to keep the charger on the battery all the time over the summer, so that it stays topped of, or would that be bad for the battery? Should I only charge it with the solar charger every few weeks and then disconnect it?
