High Voltage Three-phase Inverter Charger SMA Sunny Island X 30kW SI30-20

Product description

The SMA Sunny Island X 30kW SI30-20 Three-Phase HV Inverter Charger is the heart of self-consumption and hybrid installations seeking intelligent energy control without the need for backup. Designed and manufactured in Germany, it offers up to 30 kW of nominal power and a maximum efficiency of 98%, integrating Modbus TCP/Speedwire and WLAN communications as standard for monitoring in Sunny Portal powered by ennexOS and advanced state of charge (SOC) management. Its AC-coupling architecture allows it to be combined with existing photovoltaic inverters and to optimize the use of self-generated energy.

Main features

• Nominal output power: 30 kW (30 kVA) three-phase; nominal current 45.6 A per phase.
• HV battery input with integrated DC/DC converter: range 200–980 VDC, max. usable input current 150 A.
• Max. efficiency 98% (European efficiency 97.6%) and power factor 1, adjustable from 0 ind to 0 cap.
• Enclosure IP65 / NEMA 4X, active cooling, and operation from −25 °C to +60 °C (derating >45 °C).
• Integrated grid energy management: optimization of self-consumption, peak power limitation, and multi-use profiles.
• Connectivity: Modbus TCP, Speedwire (Ethernet), and WLAN; native integration with Sunny Portal (ennexOS).

Advantages or benefits

• No backup in grid-connected mode: ideal for projects prioritizing self-consumption and peak control without the need for UPS.
• Modular scalability: expand power and battery capacity in existing AC-coupled configurations.
• High robustness: IP65 and climate class 4K4/4Z4/4S2/4M3/4C2 for demanding climates (desert, tropical, or snow).
• Total transparency: centralized monitoring and remote parameterization via Data Manager M and Sunny Portal.
• Compliance and quality: three-phase inverter without galvanic isolation, manufactured in Germany, with a 10-year warranty (5 + 5 with registration).

Purpose or applications

Perfect for commercial and industrial self-consumption without the need for backup, AC microgrids with generator management via Connection Box, and peak-shaving projects, demand control, or photovoltaic integration in buildings, farms, workshops, and small industries. Also suitable for off-grid systems with generator and Sunny Island X Connection Box (AC source management and synchronization).
