What Ozora observes in practice
Both brands have strengths and weaknesses. The choice between them should take into account: purchase price, installer network in your region, compatibility with the electrical project, and after-sales support. For those who already have defective equipment, the repair cost is practically the same regardless of the brand.
Which one burns out more?
The frequency of failures is mainly influenced by the quality of the installation (grounding, SPD, connections) and the stability of the local electrical grid — not by the brand itself. Well-installed equipment with an adequate SPD has a much longer lifespan regardless of the manufacturer.
