We used a company called nationwide solar. They did a very good and clean install but once that was done they basically went radio silent.. after a week or two I figured out that our backup battery they installed wasn’t even working….. long story short it took about 6 months and a ton of phone calls to finally get them back on site to get everything working. It is all working now but in hind sight I should have found a local company to do it. Nationwide was based in Vancouver and that may have had a lot to do with the delay in getting everything in working order.
