Модернізація охолодження інвертора 3kW. Регулювання обертів вентиляторів, продувка, фільтри.

In this video I upgrade the cooling system of a 24V 3kW inverter. I make sure there is constant light blowing at low speeds, I rotate the fans so that the air flow is from bottom to top, I replace the 60mm fans with 80mm and install speed control boards to make the temperature regime that suits me better. After upgrading, I check under load.
