It usually is fine however this is the first time we have left the trailer in a park unattended for a few days. Generally generator is put on a few time thoughout day for brewing coffee, movies, patio lights etc.... Thanks!!
Gravity test is the best way to know the battery condition. Check the water level, charge fully, let rest for couple hours then test each cell.
If it has died a few times the battery will last half of the time it use too. Meaning from full state of charge as the chart shows, if it was a 100Ah Type 27, you would probably only get 50Ah.
This depends on the battery as well.
Also, If you have a bad cell in the batt, it takes out the good cells.
The idea for the diagram was to see how you solar controller was connected to the 12V system.
Hope this helps.
