OUTBACK MPPT 80 FLEXPOWER

[BKY2003]

The Schneider shows the battery bank is a 48 volt system . And fully charged at 53.3 volts

The Schneider inverter and Outback charge controller have different wires and different fuses, right?

This is like saying, my neighbor's house has power so mine must too. You can't relate those two facts without testing. There are failure points between the two.

Can you please just measure the voltage at the charge controller? Like has been requested.
Check your fuses or breakers.

A failed fan isn't going to cause the low voltage readings.

 

[BKY2003]

Yeah, I don’t think it’s the fan either.

Also if he is pushing the 60 plus volts from the Outback it should shut the batteries down. In theory.

That was probably open circuit voltage output from the charge controller, before it reacted to the open circuit and dropped battery voltage down to near 0

 

[Bambinoruth714]

I noticed that too ! Something's not right there I think.

I don't understand , what was wrong?

 

[Hedges]

According to the display on your Outback mppt 80, it sees 1.9V coming from battery.
If correct, that could be why it doesn't work.

Please put a DMM on the battery terminals of the Outback and tell us what voltage is there.
If different from voltage of battery itself, check with DMM to find a bad connection.

I think there is something wrong with the FM80.
