Worst service I have experienced in my life. Do not use this guys.

Installed a system. No backup service provided after payment was done. System runs 80% of time off the grit because they have not done correct system setup. Battery communication cables doesn't work router on system doesn't work. The have promised me 4 times a week they will be here since the 21 September and today the 4th August I have given up with all the excuses they use why they cannot or do not have time. No Coc was given to me that job was done according to standards.
