enwitec switchover device for 3 x SMA Sunny Island and up to 125 kW throughput power
A backup power system safely disconnects the connected PV system and load distribution from the public grid in the event of a grid failure and simultaneously provides the customer with a backup power supply.
This option with a continuous power of 125 kW allows three SMA Sunny Island battery inverters to be fed into the grid, whereby the grid disconnection is always 3-phase and all-pole. In addition, enwitec develops and produces customer-specific variants with higher power ratings and a wide range of other requirements.
Technical data:
- Battery inverter connection: 3 SMA Sunny Island units
- PV inverter connection: indirect, PV inverters are connected in the house distribution box
- Incl. SMA Home Manager 2.0
- True 120° phase-shifted backup current
- All-pole mains disconnection
- Max. back-up fuse on the mains side: 250 A
- Max. thermal throughput: 125 kW
