MPPT 75/15
Not connected to solar or shore power and fan speed 3 doesn't register as - current in the battery field.
ANY configuration NEVER shows - current. When solar is added I see + current.
Installation is EXACTLY as described in the manual and quick start diagram
In addition I have a BVm 712 connected and I get the same results under the same configurations as above.
Can this controller even show - current?
Thanks

What do you mean by "fan speed 3" ?
Can you give us some pictures of the system and/or a wiring diagram?
Thank you for your prompt reply. Please see the pdf, hopefully it will answer your questions so you can help me.
The MPPT can only show it's own charging current(and loads connected to the load output of the MPPT).
Only the BMV can show you other (dis-)charge currents.
Fan speed 3 is the exhaust fan inside the trailer that this system is a part of...
Ok,
I'm still researching and I found this comment in the

"Battery - Current This reading shows the current flowing-to, or drawn-from the battery
terminals of the Solar charger. Note that in the case of the 100/20 Solar chargers and smaller -
which have a dedicated load output - a Positive notation alongside the current reading means
that current is flowing to the battery; whereas a Negative notation means that current is being
drawn from the battery."
The comment about the NEGATIVE notation is my question. Why can't I see NEGATIVE flow from the battery? Must there be a LOAD connected to the MPPT? If that is so, can I rework it so it shows me the NEGATIVE flow without a specific load attached to the MPPT?
Thanks,
