Tesla Powerwall 2 AC Lithium Battery 13.5 kWh

Product description

The Tesla Powerwall 2 AC 13.5 kWh Lithium Battery is a fully integrated AC energy storage system, designed to maximize solar self-consumption and provide stable backup for homes and small businesses. With 13.5 kWh of usable energy, 5 kW continuous power, and single-phase operation at 230 V/50 Hz, this lithium solution combines high energy density, simple installation, and advanced IP67 protection to operate safely both indoors and outdoors.

Main features

• Usable energy: 13.5 kWh (14 kWh total energy).
• Actual continuous power: 5 kW for charging and discharging (5 kVA).
• AC connection: 230 V, single-phase, 50 Hz; adjustable power factor ±1.0.
• System round-trip efficiency: 90% (AC→battery→AC).
• Degree of protection: IP67 for battery/electronics and IP56 for wiring compartment.
• Demanding environment: -20 °C to 50 °C, humidity up to 100% (with condensation), <40 dBA at 1 m.

Advantages or benefits

• More savings: stores photovoltaic surplus and reduces energy imported from the grid.
• Reliable backup: 5 kW power to cover critical loads when supply is interrupted.
• Simplified installation: compact equipment, wall or floor mounting, and AC connection without modifying the existing PV field.
• Durability and safety: sealed enclosure (IP67) and international certifications for prolonged use.
• Silent operation: less than 40 dBA, ideal for residential use.

Purpose or applications

The Powerwall 2 is suitable for homes with solar self-consumption seeking energy independence and service continuity, small businesses requiring backup during grid outages, and residential projects with single-phase AC storage needs at 230 V. It can also be integrated into existing installations without changing the photovoltaic inverter, as it operates on the grid side.
