Wie unterscheiden sich DC-gekoppelte und AC-gekoppelte Architekturen bei LiFePO4-Solarspeichersystemen und wann sollte jeweils welche verwendet werden?
The choice between DC-coupled and AC-coupled architectures significantly impacts system performance:DC-Coupled: Connects batteries directly to the PV array before inversion. Advantages include higher round-trip efficiency (avoiding double conversion losses) and better suitability for new solar installations. Ideal for maximizing solar self-consumption.AC-Coupled: Interfaces with the facility's AC distribution. Offers greater flexibility for retrofits, load-side management, and...
