At night the solar produces zero power, so if you have anything on in the trailer, consumed aH is always going to show a negative number first thing in the morning. Then, as the solar produces power, that negative number should gradually diminish (as long as solar power in > power being used) until consumed aH gets back down to zero.Joel said:
But the shunt reading confused me. Around noon yesterday it said "consumed Ah" was 0Ah, even though the trailer had been "boondockiong" in my driveway for four days, and a few days before it read -25Ah. This morning at 6:30 a.m. I checked again and overnight the battery had dropped to 13.07v and consumed Ah was -27Ah.
Does that seem normal? I can see how the solar charge varies, but how can I tell what my usage is, and more specifically, what I can do to reduce that usage?
