We purchased a 2021 Tab320 boondock which is equipped with roof mounted panels. When I look at my Victron app it indicates 0w solar. The history indicates there is no record of solar yield. Why is my solar not working (apparently)?
Pls post the settings of the charger…
Something is charging your battery though since it is showing 14.4v which is around most absorptions for 12v. And it is increasing from the min voltage.
Battery min is interesting at 0v as well as it shows there is either a battery shutdown or disconnect between the mppt and the bank.
For the most part, the PV max voltage is not more than 5v above the battery voltage.
And your one showing float there, means no charging is seen to be needed.
This is definitely something needed here.
I’d say the charger is not connected to a battery, with sun the voltage on the output goes up to absorption level.
That would explain the constant 0 as min voltage.

It doesn’t matter what the settings are…its not connected to the battery!
@City4me
Check fuses definitely.
I checked the fuses at the battery and at the victron. What else could it be?
Bad connector, crimping error (isolation).
Check for continuity on plus and minus sides.
Is the mppt charging a lead acid battery?
Yes it is lead acid not lithium
So a 0v is technically only possible when you have lead acid if the battery connection has been broken or has a high resistance.
You will need to switch off the connection to the pv panels and check for voltage on the mppt terminals.
I think I’m going to have to take my Tab in for service. I’m way out of my depth with anything related to electronics. More information about the situation: I tried hooking up my portable solar panels to the external solar input port to see if the problem was with the connection to the rooftop panels. I plugged them in and checked the Victron app and still 0w. I unplugged the panels and noticed a burning smell. Apparently the junction box melted. Now there is no longer a signal from the Victron and the light is off on the mppt unit.
Well, you did have 19-21v on the solar side, so it wasn’t necessary to connect the external panel, but what is done is done.
Good luck.
Thanks for your help
