With DC coupling, the PV array and the battery storage system are connected to one another on the DC side of the inverter. As a result, the battery inverter as well as an additional transformer and medium-voltage switch gear are no longer required. Short cable routes minimize energy losses in the lines – the entire system becomes even more efficient. Fewer components, less cabling:with DC-coupled systems, PV system operators save on investment costs.

Due to the intermittent, fluctuating and unpredictable factors of new energy power generation, large-scale power access will inevitably increase the difficulties of power grid regulation, and may cause large scale of energy abandon. Adding energy storage system in the power generation side can solve these problems. The energy that can not be consumed can be stored and released when the power generation is insufficient or the power consumption peak is high, so as to smooth the power generation and utilization, make up for the defects of unstable power generation and avoid waste.

Some remote, non-grid areas usually require self-built power grids because of their small population and their long distance from the main grid lines. Using renewable energy to generate electricity and using microgrid technology is a wise solution.
