Hi all
I'm new here and very new to openinverter tech.
I have the 3gen open board and want to use it with a 1 gen leaf inverter but the current sensors pole are reversed ...question..how do I config this on the software provided????? Thanks.

Hi all
I'm trying to find the meaning of OCURLIM. so I know what is actually going on .. can someone explain the meaning of this ..thanks.

There are 4 hardware comparators on board that trigger an inhibit signal as soon as the current goes out of range of ocurlim. Inhibit means all IGBTs immediately switch off when the signal is triggered.
Say you set ocurlim=400 then current from the sensors must be within -400A to 400A to NOT trigger inhibit. ocurlim must always have the same sign as ilXgain
