I have an off grid installation with an EasySolar 48/5000/70 MPPT 150/100 running at full output power. I've installed a new Multiplus II with its own PV and batteries so completely separated from the EasySolar. Is it possible to do AC Coupling with both installations ? AC Out 1A of the EasySolar with AC Out 2 of the Multiplus II or install the Multiplus II AC out as a power Assist to the EasySolar ?
