EXCELLENT SERVICE
Great service 👏 thank you
I recently purchased an inverter from The Solar Step, and I couldn’t be more impressed with the experience. I placed my order on Monday, and it was delivered to Pietermaritzburg by Wednesday—incredible turnaround time!
A special shoutout to Kersh, who kept me updated every step of the way. Her expert product knowledge was top-tier, and she went above and beyond by referring me to a dedicated technician who helped verify the exact battery and inverter compatibility before setup.
