What is an automatic grid disconnection device?This is the state-of-the-art automatic disconnection device, which guaran-tees that the inverters in the grid have a very high availability, and can easily adapt to all grid conditions around the world. The SMA grid guard® 2 is available in the various Sunny Boy and Sunny Mini Central inverter models. Why an Automatic Grid Disconnection Device?.
What is automatic disconnection?In this active form of grid monitoring, the automatic disconnection device consists of two MSD ́s which are independent of each other and connected in series. Each of these devices continually monitors the quality of the connected grid by checking the voltage, frequency and impedance.
Can a grid-feeding inverter be disconnected?For all work performed on the grid, it is necessary that all energy sources, including grid-feeding invert-ers, can be disconnected from the power grid at any time. In the case of inverters, this disconnection preferably takes place by means of an automatic grid disconnection device, as described in the 1999 standard, E DIN VDE 0126, as MSD.
What is a battery inverter with automatic disconnection device?Battery inverter with automatic disconnection device with single-phase mains surveillance in accordance with Engineering Recommendation G98 Issue 1 Amendment 3 with a sin- gle parallel coupling via an inverter to the public mains supply. The automatic disconnec- tion device is an integral part of the aforementioned inverter.
What are the benefits of a decentralized generator system?It prevents unintentional feeding from a decentralized generator system into a sub-grid which is disconnected from the rest of the dis-tribution grid (stand-alone grid operation). Thus, it provides maximum protection against inadmissible voltages and frequencies for staff during mainte-nance work, and also for consume
