I had four AM100 Solar Panels and the HPV-30DR Controller installed. You can read the specifications on their web site:
I am seeing charging amps of 20 to 25 amps on a sunny day.
I did not have any new batteries installed. If I find that the four lead-acid house batteries I have now are insufficient, I will swap them out for glass mat batteries and try to figure out how to add four more batteries. The solar controller also can handle up to six panels, so I can add two more, provided I can find space on the roof. (It's getting a little crowded up there.)
I wanted to use an installer that AM Solar recommended. Since they did not have anyone in Texas on their list, I drove to Albuquerque to have the job done. Mike Sylvester did the installation.
