Image CaptionI have a Victron mppt 100/20. It has been working fine and then yesterday I noticed that my ammeter was showing no charge was coming in from the solar panels. Today I checked my connections and found a loose wire. After I fixed the loose wire the mppt came back on but still failed to charge. My ammeter shows that my batteries are at 70% so the mppt controller should be sending power but it’s not.
Low battery voltage of 0.01v?
Have you checked all fuses / breakers between the mppt and battery?
Check the fuse in the bottom of the mppt.
I am seeing this too, when I'm in float, everything zeroes out, it's like it's only reporting the energy that is passed through to the battery.
@Jason Greenberg But does it work in absorption, and do you still see battery volts in float. If do then you do not have the issue in the OP. Do you have a Smart Battery Sense or DVCC enabled as thiese supply the battery amps to the SmartSolar. Do you have a managed battery that could be telling the SmartSolar to stop charging. More details required.
