2024 Tab 400 with MultiPlus 12-3000-120-50-120v and 400 amps of BattleBorn batteries ( Black Canyon ) with SmartShunt 500A/50mV is under performing. At various SOC above 50% the Victron system will run the Alde heating system at 950 W without shore power, no problem. However, as soon as I tell Alde to heat faster by toggling from 1kW to 2kW the MultiPlus will kick off and present a " Low Battery " notification. The above will occur at all SOC with shore power disconnected. Any thoughts ?

The MultiPlus will draw close to 200 amps to run the 2kw Alde. It would take only 0.01 ohms in all the battery to MP wiring to cause a 2 volt loss at that current. That is a pretty low resistance threshold to accomplish in high current wiring...

Do you know what the low voltage limit is for the MultiPlus?
Is it adjustable?
If the voltage loss is similar to my example above, 2 volts at 200 amps, then there is 400 watts lost. That is significant heat somewhere, likely everywhere along the MP to batteries wiring. Thermal imaging has been used to find trouble spots by another member.
