Battery monitor doesn't show current coming from solar controller

Hello,

Just had a solar installed on my rv.. 150/85-mc4 sending amps straight to the battery bypassing shunt..

The engineer who installed the system is said that it was done this way to maximize efficiency.


Battery monitor 712 is not taking amps coming from mppt controller in consideration.. I assume negative from solar controller MUST go to the shunt and not straight to the battery in order for battery monitor to see incoming amps or is it a preference and I might be missing something?


Any help appreciated, thank you

Correct; installed this way is simply wrong. I’m sorry, but there is no other way to put it.
