Will smart MPPT 100/50 show an error if internal fuse blown?

screenshot-20230526-113946.jpgMPPT 100/50 undated firmware 4 days ago. Now will not charge. Do not know if related. System shows 65 volts in but no charging. I see current in PV input lines. Victron Connect is showing NO errors. I am stumped.screenshot-20230528-081734.jpg

Have you tired a power cycle?

Disconnect pv, disconnect battery.

Reconnect battery, check settings, reconnect pv.

You could also try a reset to defaults and then re program after that. If it is still not charging then there may be an issue internally.

How did you measure current in the PV? with clamp meter?

I'm curious about your daily logged battery V's, Do you have something else charging at the same time?

I have tried the reset to defaults and reprogram. I have also disconnected solar and unplugged from the battery to get a reset. I would expect some type of error if it is an internal fuse, but I see none.
