BlueNova Warranty Support – Poor Service and No Resolution

BlueNova Warranty Support – Poor Service and No Resolution

I am extremely disappointed with the level of support received from BlueNova regarding the failure of two BlueNova battery units currently under warranty.

I specifically chose to purchase BlueNova products to support a local South African manufacturer, which makes this experience even more disappointing.

According to the BMS data obtained directly from the batteries, there is a clear and critical cell imbalance, with one cell dropping to 2.629V while the rest remain around 3.28–3.32V. This indicates a cell-level failure within one of the units.

Despite this, BlueNova support continues to provide generic explanations, referring to possible inverter settings, wiring, or surge currents, without addressing the actual cell-level fault reflected in their own BMS data.

I have reached out to several members of senior management, however my emails have gone unanswered. The only correspondence received to date has been from the support department, with no escalation or resolution.

The batteries are only 4 years old, and this situation is now having a direct impact on my household. I have young children who rely on stable power at night to manage allergies, and the lack of a reliable system is affecting us daily.

This has resulted in ongoing back-and-forth emails with no clear diagnosis, accountability, or resolution.

At this stage: • The issue has been clearly identified from the BMS data • The response from support has been vague and non-committal • No progress has been made toward repair or replacement under warranty

As a customer, I expect a professional technical assessment and a clear path to resolution — not repeated deflection and delays.

I am now requesting that BlueNova: • Finalise the warranty process • Provide a clear timeline for repair or replacement of the affected units.

I hope this matter can be resolved urgently, as the current level of service is not acceptable.
