Different spec from what I ordered

I bought Inkwenkwezi Hybrid Inverter 5000VA 48V MPPT 5KVA/5000W through Takealot. the spec was as follows: Built-in MPPT solar charge controller (80A) & Max solar voltage (VOC): 145 VDC. I received low spec inverter with Built-in MPPT solar charge controller (50A) and Max solar voltage (VOC): 105 VDC. They're not honest at all. I tried to review the product on Takealot site, my review was rejected. Looks like Takealot protects these dishonest suppliers
