What to check first
Note time of day, shade, weather, controller error and battery type. Compare to the controller manual; do not disconnect energized arrays casually.
When to get help
Ask for a qualified diagnosis before choosing a panel, controller or battery upgrade.
Your RV’s make, model and component instructions control. Stop use and seek qualified help for propane odor, smoke, active electrical danger, unsafe braking or other immediate hazards. This guide does not diagnose your RV or establish part compatibility.
Next step
Check the exact component manual and model number before following a model-specific procedure.
