    Solar is bringing in 347W, battery is bringing 158W,
    and the load is 74W. Never shows the battery being charged from Solar. Any ideas?

    Also the MPPT is in float and the battery monitor is showing 82% charge. What am I doing wrong?

    Is this a new install? You may have the shunt miswired. Is the sun out as the input voltage is too low?

    I’ve looked at the shunt 100 times and I swear I have it wired the correct direction but I’m going to swap the leads for good measure. I’ll report back

    Why is the DC input to the MPPT so low 53.3V, this should be somewhere closer to 100V,  battery 51.2V float? float should be ~54V,.assuming 48V nominallead acid.
    How are panels configured and what are the specs?
    What are the settings for th MPPT? 
    What battery type is in use?

    McGivor, that was at dusk. This is now at night. With the swapped shunt leads. This is even more wrong.

    That would make sense being evening didn't notice the time on the screen shot first time, but those are indeed some strange numbers on the graphics, appears the shunt is either not calibrated correctly or faulty.

    Just to be sure... are there any negative wires other than the shunt to battery wire on the battery side of the shunt (eg. DC loads, meters, other inverters)?

    How/where is the system grounded?
    Off-grid.  
    Main daytime system ~4kw panels into 2xMNClassic150 370ah 48v bank 2xOutback 3548 inverter 120v + 240v autotransformer
    Night system ~1kw panels into 1xMNClassic150 700ah 12v bank morningstar 300w inverter

    This morning. Rewired the shunt. Check the negative wires. Why doesn’t the battery monitor know when the mppt is charging?

    Just thought I would follow up. I had the solar charge controller wired to the wrong side of the shunt. Everything has been working great for a week now! Thanks for all the help everyone!
