Trouble Getting MPPT to Charge

[caymaanedge]

Finished install. Have a 12v battery setup and approx 40v coming in from 12v 2S3P panels. Can not get MPPT to charge. Reviewed all setting etc. any ideas?
Thank you

Have you tried connecting the solar panels and battery?

Sorry but not sure what that picture was telling us. The OP is a little short on details.

Any screenshots of the app?

What are the battery charging voltages you have set in the system--Float & Bulk, and also if applicable equalization?
What Did you limit the MPPT amperage to?
Any error codes?

The two screenshots I'd like to see is off the Victron Blue Tooth software that has the present production and history.

Thanks for the response. Turns out 8 had a bad connection, but all good now. Installation is complete.

Looks nice. With the panels tilted on mine, I can get about 40% more production.

How long is that RV?

I tried at end of day to get a reading tilted and flat, but between the low Ohio sun and the fact it was 3:00 the output was almost identical.

How is it going with the tilting? Are you going up top 2 or 3 times a day and moving 12 wing nuts and bolts each time? Or is that all pointing south all the time?

If my panels are faced towards the sun, sun sets in the west so panels facing west, and I tilt earlier than 30 minutes to an hour before the sunsets, my output difference is rather extreme, like two to three times the output, and around noon its still 40% difference.

One thing that makes measuring output very difficult is the batteries need juice to show you how much the panels can output. So, measuring at sunset is difficult for me because I have enough panels the batteries will be charged by noon, so I no longer need the 60 charging amps.
