Please see picture. I'm trying to figure out why no watts are being tracked as well as the crruent/amps always seems to show zero in both solar and battery section. This happens even when I plug in a space heater and put it on high. That should definitely draw some amps. Please help.
Editing to add some more photos that may help:
Thanks!
If you have the heater on high, then it cannot be possible for the battery to be 14.1V unless energy is coming from somewhere else.
I am really beginning to think that the information yo are getting via the app is old data and something has frozen. Is it posssible to diisconnect PV and battery from the MPPT and reconnect to reset the MPPT and Bluetooth dongle?
There should be a way to reset it. I will try that. I also noticed that as the sun goes down the voltage under the battery heading decreases(like down to 6 or 7 volts before the MPPT shuts off and then the bluetooth dongle shuts off). This leads me to believe that whatever is reading there isn't the voltage the battery is putting out but is somehow connected to the solar charging itself. I don't know a lot about it, but it seems to me that if nothing is drawing on the battery, the voltage shouldn't change as the sun goes down. The battery works after sunset though all night.
It's doesn't normally need to be reset, but in this case, just trying to eliminate possibilities.
You are right about the battery voltage. Sure, it should go down at sunset, but only to 12.x Volts, definitely not 6V.
So now you've got me thinking that perhaps the battery and PV wiring is transposed, but why / how? It's not easy to see from the pictures. Has it been charging at all during the day? I guess it's difficult to say.
Thanks for your help. I got a mutlimeter to test the voltage at the battery terminals. I'm pretty sure the battery voltage showing in the connect app is not corresponding with the terminal voltage. This morning I manually tested the terminal voltage and I got 11.67, but when I looked at the connect app it said the battery voltage was at 13.8 and the charger was in float mode. It's relatively sunny today and it says the solar charger is receiving 22.89 volts, yet still the app is showing 0 watts and 0 amps after several hours today.
Any other ideas? Thanks!

That battery Voltage is really low, you need to charge with the Multiplus as soon as you can.
Where did you measure the battery voltage, was it at the terminals of the actual battery or was it at the screw terminals of the MPPT? We want to measure at the screw terminals of the MPPTbattery connection to eliminate more possbilities.
I measured right at the battery screws. I plugged it into shore power after to charge, but I was really disappointed that the solar charger didn't appear to be passing through the charge. How much would temperature affect things? It's approximately 20 deg F here today. Thanks!
I'm afraid that indicates a fault with the MPPT charge controller. It seems that it can't "see" the battery. It should be measuring the same voltage that you can see on the screw terminals.
I was hope to find some sort of wiring or fuse fault, but I think we have exhasted those options. Unless someone else has better ideas than I do?
Wkirby - Great news, I think I solved it. You may have been right afterall. Do you know what the heck this thing is?
I *think* it has something to do with the previous owner setting up the RV to charge from the alternator when running, but I'm not sure. Anyway, I moved the switch from one side to the other and now the solar charger appears to be working correctly. It's showing amps, watts, and the volts under battery are matching the volts at the terminal.
Did you have a second charger connected to Batteriesystem? The charger state (float at 14.1V)and the Panel Voltage (22.8 near VOC of 36cell Moduls)looks like that. Or do you really set the Float voltage in mppt on 14.1V?
If you already have a second Charger and the MPPT float voltage is set lower than 14.1 the result is that you have no charging from MPPT to Batterie => Watt and Amp => 0
appreciate your response. This is all still quite new to me as I obtained the system as part of an RV purchase. The alternator can charge the batteries and there is a victron multiinverter and shore power connection. However, during the time of this screenshot, the alternator was off and the RV was not plugged into shore power. Do you have any other ideas or is there more information I could get you that might help troubleshoot? I'm really sorry that I'm so ignorant at how this all works.
Could you share a screenshot of the battery settings? That would help determine what is set for bulk, absorption, and float. Also, what kind of batteries are connected?
Did you find the solution?
I have the same issue. I have four roof panels connected to a 100/50 controller and two ground deploy panels with its own 100/30 controller. The settings on both controllers are identical. When I last used the roof and ground deploy panels everything worked fine. Now this issue has popped up:
The groun d deploy panels are working fine (100/30), but the roof panels (100/50) shows volts and no amps or watts.
I’ve unplugged the roof panels and the voltage drops to zero as expected. I disconnected the 100/50 controller from the panels and the battery, disabled the 100/30 charger in the app, and reinstalled the 100/50 per the directions. It didn’t solve the issue with the 100/50 showing voltage and no amps.
