We have a Multiplus 3-24 working powering an off-grid home with 1800W of PV (6 panels), a 150/60 MPPT and a Freedom Lite 5/4 battery.
I also have a redundant Axpert MKS Plus 3/24 with 4 Trojan T105s and 3x250W panels that was only used as backup in another home
Sometimes at the off-grid home we need to use a generator to charge the batteries a bit if solar output is down or if we want to run a large load. I was wondering if I could hook up the Axpert and feed the Multiplus with that full-time on the AC-in? If I added 3 more panels to the Axpert it would increase the total PV power substantially. Would the Multiplus be able to assist and power loads in excess of 3kW if it can pull eg 10A from the Axpert?
