They are good. I like the controllers, just a few nigiling things. Like the screws being zinc plated so any moisture in the air will eventually rust them.
The terminals can only accept 6mm2 wire max, and are difficult to access unless mounted high up.
And yes I said earlier, they can only really be run to 80% capacity before they start to melt.
Still, good gear
, and the updated app that allows them to network and one to be the master, works well.
