System control with the SMA System Manager
In connection with an energy meter, an SMA System Manager takes over closed-loop control at the point of interconnection and can control or regulate subordinate inverters. The System Manager also takes over system monitoring and communication to the Sunny Portal powered by ennexOS. The System Manager is the device via which the configuration of the system is made. It then applies the settings to all subordinate devices in the system. With this function, the startup time is reduced, and the costs are lowered, in particular in systems with several inverters.
