v3.50~13 GUIv2 MPPT History Incomplete

I’m running 3.50~13 with GUIv2. I went to check my MPPT 250/85 history. It has today, yesterday, but for 7 day and 30 day it is the same as yesterday. I also have a 100/50 and it is correct. I’m running v3.16 firmware on the 250/85. I have attached screen shot.




Hi,

When you look closely, you will see that the data for “Yesterday” and “Last 7 days” is not the same. The “Last 7 days” is a sum of today and yesterday with respect to the Yield. The “Max Voltage” and “Max Power” is calculated over the last N days, which in this case happens to be Yesterday. The reason for this is that for CAN connected MPPTs, the 30 day history is not available and it only has data for today and yesterday.

Kind regards,

Well that isn’t good. Is there a plan to get to 30 days of data for CAN connected MPPT’s? I can go to VE.Direct, but I really hate those connectors. I just swapped out my MPPT’s to all CAN connected, but really like having the 30 day so of data. Thanks for the reply.

Indeed, the vecan-dbus driver doesn’t provide you with more than 2 days of history because the device doesn’t broadcast itself, without being asked, more than that.
But, if you know how to talk directly with the MPPT, at CAN frame level, you can get each and every one of those 30 days.
You can try to read Victron registers 0x1050 to 0x106E. Or 0x10A0 to 0x10BE.
At least this holds true in my case (Multi RS Solar, with 2 MPPTs - CAN connected).
