What are the advantages of a DC-coupled solar storage system?
DC-coupled solutions are also beneficial for backup storage systems. When an inverter is in backup mode because the grid is temporarily down, the inverter may try to power the backed-up loads with energy from both the battery and PV. When this is done in DC-coupled solution, the energy only needs to be drawn from a single inverter.
