Status Bulk Charging w/Voltage, but Current at 0 Amps

Hello, I have a 100/15 MPPT connected to a small vehicle solar array. It currently shows a state of Bulk Charging, but it shows 0 amps under current PV and Batt.

I've checked all fuses and made sure it's set properly for my AMG battery. When I initially hooked up the MPPT it showed Amps for the current, but after about 1hour it went to 0 Amps and has never changed from there (multiple days).


Firmware has also been updated.

Just in case someone else finds this post. The following thread answered my question: https://community.victronenergy.com/questions/18415/no-watts-no-amps-but-batteries-are-ok.html


Sort explanation is I was seeing zero values because the MPPT had nothing to charge at the time.

There is a 24/7 50watt panel and a 100watt panel that is connected part time in parallel.


This was with the 100watt panel connected, and the 50watt disconnected to avoid reducing power (as a test).


I did watch the MPPT cycle from Bulk, Absorption and finally Float over a 30 minute period all while staying 0 Amps. Vehicle was off so Batts weren't getting alternator power.


I'm guessing the 20v and 12v shown in the app isn't the +5v number it goes by to start the charging process then?
