LED lights flickering with Multiplus 48/3000/35 when running microwave

I have been running a Multiplus II 24/3000/70 for the past few months with no issues, so I decided to use the same unit when I upgraded to a 48v battery bank (the Multiplus II 48/3000/35). Now my LED lights flicker when running my microwave. I didn't have this issue at all with the 24/3000/70. Thoughts?

Could you post the data of the 24 and 48v batteries? I suspect the impedance of the new unit is to high.

It's actually the same battery bank, formerly I was running two sets of 8 280ah Lifepo4 cells with a Daly 24v BMS in parallel. Now they are set up as one set of 16 with a Daly 48v BMS. Was that the data you were asking for?

Dimmable LED’s by any chance?

They are not dimmable LEDs.

Perhaps post some vrm charts showing battery voltage/current, min/max cell voltages, dcl limits and ac loads.
