Ok if you are not planning on removing. Very difficult to unlatch. Pay attention to the screw on the release end; if it sticks through too far, it will never come off.

This immediately snapped when I tried to remove it from the DIN rail. If you’re planning to install once and never touch it again, it MAY be OK, but if you have any aspirations of utilizing the inherent removal functionality, find a different solution.Of note, this is the only Victron product that I’ve had major issues with. But this is clearly a design flaw. The plastic is flimsy and thin. Back to the drawing board, Victron.Don’t waste your money.

Okay so this barely fits on a DIN rail, it's incredibly tight. Not sure how I'll get it off without breaking things but anyways that's a me problem.Have you ever bought something and been like I can't believe I paid that much for it? This is one of those things. Very expensive for what it is, two small flimsy pieces of plastic with a few screws. Definitely not worth the listed price.

The kit (small) is not just for the Cerbo, it is fully compatible with Victron SmartSolar MPPT 100/20A!

Fits, typical Victron - expensive.
