Hello,
I have a pair of MultiPlus II inverters in parallel on a single phase, running in ESS mode. When I switch a large (12KW) load on, most of the time the system works as I'd expect: the MPs deliver about 8KW, and the grid shows about 4KW incoming. Occasionally, though, I get the error below. How can I prevent this overload happening? I understand that if I turned on a 12KW load in a "grid lost" scenario it would cause an overload, but surely in ESS the system should be smart enough not to "overload itself"?
Thanks for any advice,
