Mecer Invert - Don't waist your money

Mecer Inverter - Don't waist your money. Spent R19K on a Mecer 2000w Inverter in May 2023 to run my houses surveillance camera's of 80w during load shedding. 4 month old and the inverter does not last 2hrs. Mustek/Mecer are of no help what so ever. I have to take the 60kg plus - invert back to builders warehouse to book it in. I don't want this inverter anymore I want my money back to buy a product that is RELIABLE and support by the manufacture.
