DC couple Quattro + RS Multi

Hi everyone,


Would it be possible to DC couple a Quattro and an RS Multi?

My Quattro is acting up, not charging with excess (I have both Fronius on AC input and Huawei on AC Output with AC sensor). Right now, the Quattro is with my old lead-acid batteries (i hoped by removing the JK BMS from equation, it would start charging as it would see a "dumb" battery pack with only the BMV700 shunt). But what I hope to do soon, is expand the new LFP pack and leverage both inverters on the same pack (the RS alone might not be able to cover all my loads as I run exclusively on electric with 2kw boiler, 2kw heatpump, all electric appliances, etc.).


I think best would be to use RS with it's own 3kw array, DC coupled with Quattro, which would have the 5kw Huawei on AC Out and on quattro's AC IN have the Fronius between him and the grid.


Opened to advice :)

Thanks!
