Introduction
For operators in areas with a good enough grid, we have designed a solar retrofit system with solar optimizers. This system can be easily retrofitted onto existing infrastructure and will not occupy cabinet space. Each solar panel integrates with a solar optimizer, which makes it possible to monitor the working status of each solar panel, reduce the impact of shadow on solar panels and increase the output of solar system.
