I believe it’s a misrepresentation from VRM part in case of Multi RS.
The inverter output (ACOUT1) is off when the inverter is off.
The other output (ACOUT2) is just a plain mirror of ACIN.
So, in a way, ACOUT1 can be considered an output for critical loads.
Thank you, l also believe in VRM team and they’re coding progress. It’s really good job.
Of course, ACOUT1 for essential loads and ACOUT2 for nonessential loads is best solution for hybrid systems.
It will be much better, in case Multi RS Solar and other products with new chipsets and “high frequency” technology, - if it no needs additional power meter for VRM correctly draws AC Loads and Critical loads, I think Multi RS has all necessary “in the box”
