The Sunny Boy Multi-String lets you assemble high
power PV-plants with maximum yield. Different orientation and different module
types are processed by separate MPP-trackers that also compensate different
module numbers in the different strings and partial shadings that otherwise
result in massive yield losses.
The attractive specific price makes the Multi-String
one of the most affordable members of the Sunny Boy Family. Stainless aluminum
enclosure, snap cable connectors for the connection of the strings and a full
compatibility to the Sunny Family communication system make the Sunny Boy Multi-String
an interesting inverter for your plant.
Features:
- Transformerless with integrated all-pole sensitive
residual current detection
- SMA grid guard® (MSD)
- Diagnosis and communication via Powerline Communication,
radio
transmission or via data cable (RS232 or RS485)
- Extended temperature range –25 °C
to +60 °C
- For outdoor and indoor installation
- Connection of DC input with waterproof snap
cable connectors
- Surge voltage protection with integrated thermally
monitored varistors
- Suitable for different strings due to separate MPP-Tracking
- Extended input voltage range (125 to 750 V DC)
