How to build your Energy Load manager

Wednesday, September 12th, 2018

A detailed instructions of how to build an Energy Load manager from Open Electronics: When the instantaneous power consumption exceeds the set values, it selectively disconnects the users, in order to prevent the electric meter to cut the power to disconnect. The management of the electricity users at home, intended...
