Palmetto Reviews
Had a problem with communication, but Scott Jones (sales) went to work and got it straightened out. Dave and his crew did a great job with installation and even with a problem with the inverter Dave got it fixed and it is running great. I do appreciate Dave and Scott following up and doing what they said they would do.
