They have a 25 kW backfeed limit. Its a 4 stack radian system with about 25 kW of solar and 10 kW of wind. The wind is AC coupled Bergey and the solar is DC coupled with FM100s. My idea was to use the Radians to limit the solar to 15 kW and let the wind do its thing. However, the utility doesn't like the idea that this limit could be changed without their knowledge.</div><div><br></div><div>Has anyone designed and/or implemented a backfeed limiting circuit that could knock some charge controllers off-line in case that 25 kW limit is reached.
