Hello. I have a 30 W panel and an Adventurer controller charging two Interstate 12V deep cycle batteries in a motor home.
When I first hooked it up the sytem couldn't keep the batteries charged with the solar system, so I had the batteries checked. The Interstate tech hooked up his computer and said the batteries were not capable of holding a charge so I got two new batteries.
Now, with no load, the system keeps the batteries at 12.5-13.5 V which is good news.
What I don't understand is that even with the batteries at 13.1 V on the readout of the Adventurer, it says the battery is only 41% charged.
Is this because there are two batteries? Is there a setting in the controller which needs to be changed?
If the controller thinks that the batteries are only 41% charged will it overcharge the batteries?
My RV also has a converter which charges the batteries. Would it be better for the batteries to charge them with the solar panels and the up-to-date Adventurer controller or should I plug in the converter when I am near 120V power.
Any guidance is appreciated as I am new to solar.
Best,
Tony
