I just got a CODE 51 on one of my LV2424, i have two in parallel for 220V they've been running for 2 years.
yesterday one of them showed CODE 51 witch means over current, but it wasn't on when this happened.

It had 2s2p 250w panels for about 1000w total, way lower than its max.
disconnected it for a day and i still have the code, any ideas? Or how to fix, theres a similar thread here wth a diferent MPP where they had to purchase a bord from MPP to fix it.
 
Hi was this a problem with the board? I have an F51 code also. Mpp solar inverter 11kw
