GoodWe HK3000 is a solution designed to monitor the energy consumption of consumers in real time around the clock. Using the best design principles, the HK3000 is tailored to the needs of homeowners and only needs an internet connection. It consists of a smart meter and a Wi-Fi/LAN communication module. An additional advantage of GoodWe's HK3000 is that it can be used in grid-connected installations with GoodWe inverters and even in installations without photovoltaics. It is the most important component for keeping records of energy consumption. The data, updated every 60 seconds, is uploaded to the cloud and stored there. End users can benefit from a number of additional advantages as they learn more about their electricity consumption and the source from which it is generated. In addition, when used together with a GoodWe inverter, the HK3000 can reduce the power sent to the grid.
