I am preparing for my first spring outing with my Black Canyon T@B 360. The solar system remains a bit of a mystery to me. Sitting in my driveway here in Maryland the solar panels aren't keeping the system topped up to 100%. The only way to stay charged is the shore power. My previous T@320 with 200 watts solar and 300ah of AGM batteries was easily kept charged in winter without shore power. I had that for five years. My new camper is sitting on the north side of my house so it doesn't have direct sun, but it does have full exposure to the sky. This should bring in more than the 15-88 watts that the system says it is providing.
The dealer has told me that because the lithium system needs to run the battery heater, the solar panels can't keep it charged. To me, this means that the lithium upgrade makes the T@B 360 less effective as a camper for the cooler shoulder season because the solar system can't keep up with the battery heater.
What am I missing? Is there something wrong. I do have experience with solar panels and with T@Bs, so I don't think I am crazy, BUT I haven't worked with lithium.
