Equipment
- MultiPlus II GX 48/5000/70-50
- Autotransformer 120/240-100
- SmartSolar MPPT 250/100 rev2
MultiPlus Software
- Firmware Version 494
- VenusOS 2.81 + GuiMods (!)
- Product ID 2623
Issues
- VRM warns "Installation too busy. Realtime data link disabled."
- VRM realtime data never happens and doesn't update until refreshed (still refreshing to lagging data)
- Local & remote console both show lagging data (local console approximately 15s behind)
- Hum from inductive loads
The issues mentioned above began on 1/ 31, leading me to check firmware status and see if the MultiPlus took a firmware update. It had. I figured the VRM issues were caused by a firmware bug, but the hum is very strange. It's the same noise I've heard from the microwave and espresso machine when using our backup inverter (non-pure sine). I haven't looked at the sine wave yet, but console shows us at 60.1Hz still so, not sure what's going on there.
Thought I would just deal with the data issues until others complained and a firmware update was issued. I see that this already happened, but it was for a different issue related to internal modem using PIN locked SIM. Hence, 2.81 installed with auto update still on at the time and it did not fix my issues. In fact, a bunch of my settings were lost including my AC current input limit causing me to stall out the generator last night.
Still seeing all the above issues, even after attempting several things. Option to revert to 2.73 is taken away with the issue of 2.81 update and the nanopi only stores current and one old firmware. Attempted restore to 2.80 and, as you would expect, issues still exist. Attempted to download firmware to revert to 2.73 from the Victron Professsional portal, but only 494 firmware exists for Product ID 2623.
Two Requests:
- Please fix the issues within 2.81. I was excited to see this firmware as I've been waiting for some of the implementations, such as the tank sensors. Hopefully this information is helpful in working bugs out.
- Where can I get archived firmware to revert to for my device. I absolutely have to go back to 2.73 at this point. This firmware unfortunately is not release candidate worthy yet.
