Hi there. I was also looking for installers and came across their name. We recently rented a flat at a home in Franskraal where their installation were done by J S Electrical. This was roughly two years ago. The owners were told by the company that the installation carries a 10 year warranty. One of the batteries packed up recently and now the owners are struggling to get hold of the company. The name of the installer is Stephen Malan Tel number 0834884984. I am really disgusted by their after service in the sense that they do not honour the agreement from their side. I would not encourage other people to use them in the near future. Greetings
