Best Remote Repair in Phoenix AZ

We purchased a tiny home that had an off grid system hooked up to it so we called new grid to come out and see if we were hooked up correctly.  We paid the $250 for the consultation and had two guys come out to look at the system.  I also wanted to get some extra batteries installed and a few other upgrades to make sure we were good for off grid living.  Everything seemed to be hooked up correctly is what the two guys from new grid determined.  I basically only received a printout of the user manuals from them, and certainly never got a follow up on any upgrades.  Seven months later our system failed due to an underpowered inverter (which fried) and our batteries also were unable to hold a charge and were ruined as well.  The company who is now upgrading me immediately noticed several areas that were not hooked up correctly including how the bank of batteries were wired.  I just find it sad how some companies talk the talk on the phone and just fall very short after your check is cashed.  I definitely doubt their solar knowledge and I would recommend taking your money to a more experienced company.
