We purchased an inverter. Kevin answered all our questions & kept in touch whilst we were deciding. However, although the original quote for 2 inverters was excellent we didn't know Sunboost could supply yet another. We spent valuable time meanwhile, researching the market. Because this was the only company to properly follow up on our original inquiry, we were able to continue the conversation with Kevin and get the product we preferred. He is giving us good after sales service as we need more tutoring re the internet connection to our smart phone etc. We are delighted that Sunboost is willing for us to be completely satisfied, although the inverter is installed and working properly. And if there are any problems with it in future we feel we can rely on this company to keep up the communication, which is a very important aspect of having a system fully operational for the life of our panels.
