Very neat installation, do you get any issues with heat build up in the enclosure?
We added 2 vents for natural convection air flow. Temperature is around 95F.
It’s always a challenge trying to keep the system cool when you have the equipment in an enclosure. I hope the convection air flow is sufficient to prevent you having any issues. 
Puerto Rico is a hot place, however, the system is installed at a garage and so far temperature of system has been around 90 F. In the summer it could get to 100 F. Also, the customer loads ar small (average of 250W). The system powers critical loads like refrigerator, lights, internet modem, and garage gate.
