I´ve got some Growatt MIC inverters (2pc MIC600T-LX and MIC2000T-LX) and I was wondering long time, if they are the same inverter with just different output limits.
Specs seems to be the same: Max DC Voltage 500V, MPP-Range 50V-500V, Max current 13A, same weight, same dimensions.
A tear down...
Register 121 is working for most of the Growatt-Inverters. (SPH is different) Please feel free to follow all the stuff @link
For 3000 it should be 30, 3300 -> 33, 3600 -> 36
But I don't have any of these Typ to check it.
