A method for operating an inverter and an inverter configured to convert DC power supplied from a DC power source into AC power supplied to an AC network by applying operational parameter limits which define limits for allowed operating points of the inverter, collect, during the converting, data of operational conditions related to the inverter, determine on the basis of the collected data whether the set operational parameter limits can be optimized with regard to one or more optimization criteria, and in response to determining that the set operational parameter limits can be optimized, adapt one or more of the set operational parameter limits applied in the converting on the basis of the collected data.

Method for operating inverter and inverter

A method and arrangement are provided for reducing the amount of condensed moisture inside an enclosure which encloses at least one piece of electrical equipment which is configured to receive electric power from outside the enclosure in a first electrical magnitude range (0 . . . max) and to feed electric power to outside the enclosure in a second electrical magnitude range (min. . . max). Electric power received on at least one portion (a, b, c) of the first electrical magnitude range (0 . . . max) being outside the second electrical magnitude range (min. . . max) is utilized for heating the condensed moisture for exhaustion thereof.
