Exposed Exterior Wire

I had a solar system with battery backup installed this summer in CA.During the original install they did not install all the wiring to track the production on the app. They have had to come back several times and I still have not paid them because it’s not fully functioning. After the latest visit I noticed they installed the tracking wires on the exterior of the house not in conduit, is this permitted in CA. If not does anyone know the language or code for this? Seems like a sloppy job. I’m addition they just drilled a hole into the bottom of the gateway with no seal or anything…

Thoughts?
