I have just recently completed the solar grid connect and solar design training courses and have completed a few installs as part of a team. I have been told about some SMA application for an iphone which I don’t have and have found out they are quite expensive to buy. Do you know of any other tools I could use to present a quick summary on the site of installation as I am going to be doing work for a company installing predesigned solar systems and they want me to confirm on the day of installation the technical design. I have had a look at a couple of websites mainly American and am a bit confused about the amount of products and their effectiveness and ease of use. The iphone and SMA application I was talking about was shown to us at the TAFE training institute when I was doing the course and it seemed quick and effective to give a rough estimate on the design figures.
I would appreciate any advice and suggestions you could give me.
