MC Cube buyer questions
Is the BYD MC Cube ESS an AC or DC block?
Treat the listed system as a project-configured utility battery block. The procurement schedule must state whether PCS, transformer, EMS, auxiliaries and commissioning are included.
Which compliance documents should a buyer request?
Request configuration-specific battery safety, thermal propagation, transport and system integration evidence, including current test reports rather than certificate logos alone.
How should MC Cube pricing be compared?
Normalize bids to usable delivered energy, power duration, AC or DC boundary, warranty throughput, augmentation, spares, freight, commissioning and long-term service.
