Electronic Adaptation Unit Configured to Adapt Electrical Energy Storage Devices to Devices for Converting from Direct Current to Alternating Current and Relative Operating Method

An electronic adaptation unit comprises a power limiting circuit connectable by way of a first input to a storage device, a feedback circuit, and a sensor connectable by way of a first output to an inverter. The sensor comprises an input connected to the power limiting circuit and a second output connected to the feedback circuit, and is configured to measure the instantaneous electrical energy which passes through it and to transmit, towards the feedback circuit through the second output, a measured value, proportional to the instantaneous electric energy passing through it. The feedback circuit is connected at the output to a second input of the power limiting circuit and is configured to drive the power limiting circuit according to the measured value, by simulating the behavior of a solar panel system or of a set of photovoltaic solar panels. A system and operation method are also provided.
