Hello- I bought the setup for our off grid cabin and it worked great from the day we installed (last November) until about a month and a half ago.
What we noticed was the battery bank started to slowly not reach 100 percent each day, when we were used to seeing it back to 100% by about 11:00am each day. Even on cloudy days we would see that the panels were gaining about 8-10 amps. It was not uncommmon in bright sun to see it producing 20+ amps.
Now, according to the TM 2025 battery monitor, we only gain about 0.5 - 0.9 amps at high noon! When an appliance turns on, however, we do not see the number drop into the negatives- the reading simply goes down for a moment and then back to +0.9 amps when we know from the past that the fridge draws 3.5 amps when it turns on.
Are there any quick reasons as to why this would be happening? Is it my charge controller? I find it hard to believe that on a bright sunny day the panels are only producing 1 amp.
Any tips on where to begin are greatly appreciated!
Thanks!
