Hey have you ordered your diybms boards? Thinking about getting this system also. Are there issues getting them into canada such a duty? Big downside is the scale of the order.

Hello!
Your idea about remote external limiter for GTIL2 is just perfect! Did you managed to make it work? I have the same inverter and a distance of 200 meteres between the inverter and where i measure the current from the grid. It's impossible to connect the sensor with wires. Can you please help me with more details about your way?
Thanks in advance!
