SolarEdge SE5K-AUB: battery path
Yes — for the exact supported AUB generation, SolarEdge explicitly lists a Home Battery 400V storage path. The Australian Home Battery datasheet names Residential Three Phase Solar Inverters SExK-AUB as compatible, so this is stronger than a brand-level inference.
Exact part number still matters
The current three-phase datasheet applies to the AUB family with the stated AUBTEBEU4 part-number generation. Older Australian SolarEdge three-phase hardware must not be assumed equivalent merely because the front label says SolarEdge.
Storage ≠ backup
SolarEdge's current Australian material keeps backup separate from this three-phase AUB storage pathway. BecSpec therefore reports the battery relationship as supported while not presenting SE5K-AUB as a backup-capable result.
System condition
SolarEdge's battery datasheet also specifies system constraints, including a single battery and single inverter per site for this Residential Three Phase AUB pathway and Home Network communication requirements. These are compatibility conditions, not installation instructions.
