Tip-off: BlueNova residential BESS — ISO 9001 design-control admissions on recorded call (7-year failure)
On a recorded phone call on 18 May 2026, BlueNova's Head of Aftersales Support Services admitted that the original engineers who designed and built my battery system are no longer with the company, that design records are incomplete, and that there are aspects of the legacy designs current engineers do not fully understand.
For a lithium BESS installed in homes — not a disposable gadget — that raises serious ISO 9001:2015-style questions about design control, documented information, traceability, and who carries engineering responsibility for packs still on customers' walls.
On the same call he could not guarantee the existing installation could be made to work. The practical offer was to pay again for new batteries (16 kWh unit) or return both packs — seven years after purchase, with years of repairs, loan units, workshop stays, and closed support cases while the system remained broken.
This sits next to a story MyBroadband already ran (August 2025): Reunert told shareholders Blue Nova's board had decided to sell due to continued negative performance, that it would be an "asset held for sale" and "discontinued operation", and that the Competition Commission had approved ACDC Dynamics' acquisition:
Among the battery manufacturer’s biggest customers is upmarket Gauteng residential estate Midstream.

Would MyBroadband consider reviewing this as a news story — whether as a follow-up to the Reunert/ACDC piece or a consumer investigation — to help other customers facing the same BlueNova accountability problem?
