Planning on buying the bolded * items tomorrow for our completely off grid homestead. Big purchase for us! Just posting this in case somebody sees something glaring with our mix of components who might sound the alarm and prevent me from making a costly mistake. I'm showing the 22KW ground mounted PV array (which will be split into 8 x 6-or-7-panel strings going into the 8 trackers of the two charge controllers) will produce roughly 400 amps max (22KW divided by 48V) which the MPPTs can use to charge the 48V/800AH battery bank (it can accept 800amp charging).
Biggest draw will be a 230V GSHP at our cabin and otherwise the two structures will just be wired for regular 110V outlets. The Multi-Plus from what I understand can auto-start the Honda 7000 generator to charge the batteries and supply power to the structures in case of low SOC and lack of PV power as needed.
Any comments or warnings or recommendations are greatly appreciated before we spend money tomorrow!
