I find it interesting, that you can buy a Growatt inverter that supports 2 strings up to 7000W of PV with 550v VOC, for less money than than a couple of 500+ V mppt's by themselves. I've looked found nothing much for HV MPPT, the EG4 is a single string albeit 5KW, . I think someone should build an 4 input MPPT that possibly would communicate with inverters? that handles 500+V strings in the 15A range, to manage additional solar panels that are used for charging up larger battery banks. Most folks have a fairly finite need for AC output, after which additional inverter output is no longer desired, you just want to divert the power to storage. Was curious what others think, as it appears folks are just buying inverters when all they really want is the SCC/MPPT portion of it.
