The SG110CX was the preferred choice. Thanks to its high output, the number of devices could be reduced. With multiple MPPTs (Maximum Power Point Trackers) and an IP66 protection class with a simple AC installation, all the technical requirements were met. The devices could be installed efficiently and quickly, thanks to the low weight and easy handling. This made Sungrow the first choice for solarSTEP. The two companies had successfully collaborated together in the past.
