Do good solar controllersrequire a lifetime warranty?

Companies that make solar controllersoffer all kinds of warranties for any taste. Usually, cheap models have only a 6-month warranty or do not have it at all. Average users recommend choosing a solar controllers with a two-year warranty, but we believe that the five-year warranty is much better and safer. At the same time, our team would not recommend you to buy models with a lifetime warranty since the vast majority of them is significantly overpriced.
