My MPPT controllers are networked to the BMV (network signal appearing on all devices), I know I have slider switch issue with highish voltage drop on the charge side, but this was largely solved when I networked. Now I see my MPPT is reading as high as .5V above BMV voltage on high charge, which of course takes my MPPT out of bulk early, they read correctly on low charge, I have a 1 amp fuse connected in BMV. Anyway explain please why MPPT is reading its local voltage and not the BMV networked voltage.
