I have a 20amp mppt charge controller (EP Solar tracer 20a). In the manual it states:
WARNING: Connect battery terminals to the charge controller BEFORE connecting the solar panel(s) to the charge controller. NEVER connect solar panels to charge controller until the battery is connected.
However, if the breaker (or fuse) between the battery and controller is ever tripped, then it will essentially put the system into this state.
Is there any way to prevent this from happening? Or is this not something that I should really be worried about?
Currently the charge controller is connected to the same breaker as the system load (mainly for the convince of being able to disconnect the entire system in 1 switch). I'm wondering if this might make the scenario above more likely to occur and if I shouldn't run a separate fused line to the battery directly from the charge controller.
Here is a diagram of what my current wiring looks like:
NOTE: I couldn't find the breaker symbol so I used the switch. Also the circles are junction blocks that I added for convenience
