I have several 5kVA and 3kVA inverters all of them standalone. How can I setup grid assist without having to shell out a lot of money for ESS? HUB-1 should be able to do exactly what I want to do but I can't seem to be able to force grid assist to work. Do I need external HW even with a simple HUB-1 assistant?
I know HUB-1 is "depreciated" and I don't really care.
