I have a fellow member on another site with a problem who has the factory solar package on his 2022 KZ Escape 231bh. The solar controller is showing code b001 (cannot see battery) and there is no voltage on the battery side of the solar controller. The manual shows that there should be a 30 amp fuse between the controller and the battery. The only thing I can find is 3 inline dc auto reset breakers. All three of those have continuity and appear to be working. Battery is full and all other 12v is working. I told him that the fuse should be in the Battery + line , and that if there is no battery connected, with the solar panel connected, that the controller may be damaged.. He said this rig set on the lot for weeks without a battery connected before it was sold. The sales guy even showed that the lights were working off the solar without a battery and has been working fine until this past weekend. How can this be  All I’ve read says to ensure you hook up the battery first , then you can connect the solar panels -- This is correct??? Any thoughts on his system??? |

Hi, I am the one with this issue. I thought I would post the fix in case anyone searched for this in the future.
To test to see if I had a good wire between the solar controller and the 12v auto-reset breakers, I ran a long piece of wire to the battery side of the breaker (after disconnecting the battery) and pulled it into the trailer next the to the controller. I then removed the wire from the battery side of the controller (panels already disconnected) and did a continuity test. I had a good run of wire to the breakers and had good continuity at least to the battery side of the breaker. Problem must be past the breaker, but all that is past the breaker is a bus bar and the battery itself. All other 12v systems are working. I then disassembled the breaker box (behind the battery on the hitch) and found that KZ had painted the bus bar under the breaker. The 12v breaker for the solar must have been installed later at the factory. The breaker was only making contact with the bus bar via a lock washer than must have moved from travel and was now no longer making contact. I sanded the bus bar clean and re-assembled. Everything is working now. I did note that KZ installed a 20amp breaker, when the manual calls for a 30amp. As I only have the one panel, it will not make any difference unless I add more solar. Hope that helps someone.
