I have some experience installing Axpert inverters, but only seen a Sunsynk inverter.
A few things that come to mind when deciding which one to offer a customer:
1/ Do you require a backup system? Axpert switching time is very fast, Sunsynk not so fast.
2/ Axpert cannot feed back into the grind (I do believe the newer version are hybrid), Sunsynk can.
3/ The cost of an Axpert is a lot cheaper compared to the Sunsynk.
4/ Remote viewing, both units can link remote viewing. I have installed solar assistant on all the Axpert inverters I manage, Sunsynk can also work with Solar assistant, but now has a data logger and remote viewing. It is a no brainer using remote viewing.
I will update this thread as I become more familiar with the Sunsynk unit.
