MPPT150/70 (firmware v 1.61) connected in parallel with a MultiPlus 12|3000|120 and a Orion TR Smart 12|12-30. Installation in a sailboat, with the TR Smart only supplying when the engine alternator is running.
My LiFePo BMS (2 packs, and error occurs with both) have been disconnecting from the charge function due to a high charge voltage condition. As the BMS and an active balancer manage charge and equalization, I have set all three Victron devices to a 14.0 V output. Checking each in isolation, I discovered that only the MPPT 150/70 is producing forcing a charge with > 14.3v.
On the main bluetooth display under the STATUS tab, the device reports a "voltage" consistent to what has been set. But, when I connect the MPPT device to the battery buss, the same voltage display changes to 14.7 volts (sometimes more).
I have disabled the temperature compensation, and have used the victro-supplied profile for LiFePo, changing the absorption and float voltage to 14.0 V. I have also disabled equalization.
For now I've had to keep the MPPT off the battery buss, as this high voltage is not good for my system.
Is this a bug, or a feature? Any way to fix?
