Zero After Sales Service

I bought a Solar Installation from Greenzone Energy (Nelspruit) September 2017, which included 4x6kWh Blue Nova Lithium Ion Batteries. A few months later I doubled the battery size to 48kWh in total. When I relocated to Pretoria Greenzone energy reinstalled the system in July 2019. Early April 2021 I noticed a drop in the battery performance and Blue Nova representative Mr Gerrit Bloemhof visited the installation on 15 April 2021 and arranged for the collection of the batteries for what ultimately became a warranty claim. The feedback I received was that they no longer manufacture that model and arranged for a different model to replace the defective ones. However, it turned out that the replacement models are not compatible with the remaining installed ones. It is now nearly 2 years since the original claim date and the warranty claim is still not resolved. Not even the CEO has returned my calls or contacted me by email. While I still think it is a good product and proudly support South African companies I am at worlds end with Blue Nova's after sales service. It is non-existent.
