ACDC enclosure was R1250 for 600x600x270. Rack i build out of steel that i had. Going to add welding speed connectors to make it easy to connect and disconnecting the unit. The copper bars i made out of old 3mm copper plate i had from a othet project. 
My solar instellation not finish in this photo, waiting for stuff that i order and stuff that bought on holliday that i will add when I'm back home. 
Planning to build one more or two if this one works out nicely. 

If ordering from Banggood. Use this one from my experience it is best.
