HV Inverter Charger SMA Sunny Boy Storage 2.5 SBS2.5-1VL-10 Single-phase

Product description

The SMA Sunny Boy Storage 2.5 SBS2.5-1VL-10 HV Charger Inverter Single-phase is a high-voltage battery inverter designed to expand or create self-consumption systems with AC coupling. With 2.5 kW charge and discharge power, max. efficiency of 96.8%, and IP65 enclosure, it allows integration of an HV lithium battery into new or existing photovoltaic installations — also with inverters from other manufacturers — to increase energy independence and reduce costs. Its web server, WLAN/Ethernet, and Modbus/Webconnect facilitate commissioning and monitoring in Sunny Portal / SMA Energy App, while dynamic active power limitation (0–100%) is coordinated with SMA inverters with Webconnect to achieve zero feed-in.

Main features

• Charge/discharge power: 2.5 kW (AC 2.5 kVA) at 230 V; max. AC current 11 A.
• HV lithium battery 100–500 V (Vnom 360 V); max. DC current 10 A; max. I_SC 18 A.
• Max. performance 96,8 % (EU 96.1%); transformerless topology, convection cooling, < 25 dB.
• AC coupling: suitable for new or existing plants; does not require internal PV MPPT.
• Integrated connectivity: WLAN and Ethernet (Speedwire), Webconnect, Modbus SMA/SunSpec; battery communication via CAN.
• Protection IP65, −40…+60 °C, 9.2 kg, 450×357×122 mm; 5 + 5 year warranty (registration).

Advantages or benefits

• More self-consumption with HV battery: stores solar surplus for use at night or during demand peaks.
• Ideal for retrofitting: adds storage to installations with existing on-grid inverters via AC coupling.
• Simple and fast installation: lightweight (9.2 kg), AC/DC connectors, and commissioning wizard via browser.
• Feed-in control: dynamic active power limitation (0–100%) with SMA inverters with Webconnect.
• Cloud monitoring: visualization in Sunny Portal / SMA Energy App with clear energy metrics.
• Reliability and low maintenance: fanless design, IP65, and professional-grade electronics.

Purpose or applications

Recommended for homes and small businesses seeking to integrate a high-voltage lithium battery into their self-consumption system, either in a new photovoltaic installation or in an upgrade of an existing plant. The SBS2.5-1VL-10 is perfect for AC coupling with grid-tied inverters, without the need to change the PV generator, and for scenarios with hourly tariffs, household load management, or future expansions (e.g., heat pump or electric vehicle charger).

Technical specifications

Compatibilities

Direct (official) compatibility: high-voltage lithium batteries approved by SMA (see “List of Approved Batteries”), SMA Energy Meter and Sunny Home Manager 2.0 for measurement and feed-in control; native integration with SMA inverters with Webconnect for power regulation.

Compatible accessories (not included): DC/AC Type II protections, weatherproof cabinet, cabling and AC/DC connectors, Modbus/SunSpec meters, communication gateway if integrating with third-party grid inverters.

The SMA Sunny Boy Storage 2.5 SBS2.5-1VL-10 HV Inverter Charger Single-phase adds HV storage to your self-consumption system with AC coupling, providing flexibility, efficiency, and intelligent energy management to maximize every solar kWh.
