What is a DC-coupled Solar System?

DC-Coupled system ties the PV array and battery storage system together on the DC-side of the inverter, requiring all assets to be appropriately and similarly sized in order for optimized energy storage and power flow. Mid to large-scale solar is a non-reversible trend in the energy mix of the U.S. and world.

Is DC collection a hotspot in the field of PV energy?

The research on DC collection of PV systems is becoming a hotspot in the field of PV energy [ 4 - 18 ]. A modular multilevel converter (MMC) based PV system has been proposed in [ 4 - 7 ], where each PV array is connected to the capacitors of each submodule (SM) of the MMC through a DC-DC converter with maximum power point tracking (MPPT) control.

Why do solar PV modules need a DC-DC converter?

The major issue of solar PV modules is low supply voltage which is increased by introducing the wide input voltage DC-DC converter. The merits of this introduced converter are low-level voltage stress on diodes, good quality supply power, high voltage gain, plus low implementation cost.

How to choose a DC cable for a solar system?

The type of DC cable is selected according to the short-circuit current ( ), the maximum system voltage ( ), the ambient conditions ( ), and according to the relevant standards [ 11 ].
