AC / DC in comparison
AC systems
- Has its own battery inverter and is operated independently of the PV system (compatible with any PV system)
- Two conversion stages required
- Minimal conversion losses in the overall efficiency
- Particularly suitable for retrofitting
- Greater reliability and easy troubleshooting
- More flexible, as compatible with all PV systems
DC systems
- Coupling with an external battery inverter (communication via CAN bus or RS-485)
- Only one conversion stage required
- Higher overall efficiency
- Particularly suitable for new buildings
- Less space and acquisition costs required
- Compatibility with PV inverter required
