Solar Power Storage-DC Bus Solution
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.
With DC coupling, the battery and the PV on the DC side. The central inverter is array are connected to a central inverter then connected to a MV transformer to complete the system.
System costs are minimalized as there are fewer components (no separate inverters or transformers are needed for the battery storage system)
Energy losses in conversion and storage are reduced
Full load hours are optimized
Faster installation and lower maintenance cost since the system is made up of fewer components.
