Tesla Powerwall 3 13.5kWh Solar Battery Storage Performance and Capacity

The Tesla Powerwall 3 13.5kWh solar battery storage provides 13.5 kWh of usable energy at 100 percent depth of discharge, ideal for covering evening and overnight household loads. Continuous AC output power is configurable up to 11.04 kW on Australian single-phase grids, with load start capability of 185 locked rotor amps to handle motor-driven appliances such as air conditioners, pumps and EV chargers without interruption. The integrated hybrid inverter accepts up to 20 kW of solar input across multiple MPPTs, eliminating the need for a separate solar inverter in many installations.

Solar-to-home efficiency reaches 97.5 percent while solar-to-battery-to-home round-trip efficiency is rated at 89 percent under standard conditions, delivering high system performance for both direct solar use and stored energy. Dimensions measure 1105 x 609 x 193 mm and total installed weight is approximately 130 kg, allowing flexible wall or floor mounting indoors or outdoors. Scalability supports up to three Expansion units for a maximum of 54 kWh per Powerwall 3 and up to four Powerwall 3 units in a single system for greater capacity and power.

Battery chemistry is lithium iron phosphate for enhanced thermal stability and long cycle life. Operating temperature range spans minus 20 to plus 50 degrees Celsius with active thermal management, ensuring reliable performance across Australian climates including cold mornings and hot summer days.

Tesla Powerwall 3 13.5kWh solar battery storage The system features a fully integrated hybrid inverter and works with Tesla Backup Gateway 2 for seamless whole-home or partial-home backup with rapid transition. Connectivity includes Wi-Fi, Ethernet and cellular options, with monitoring and control handled exclusively through the Tesla mobile app for real-time energy data, time-based control and over-the-air updates. The design supports on-grid operation with solar self-consumption, time-of-use shifting and full backup capability. SEIA vision for energy storage growth

Enclosure protection reaches IP67 for the battery and power electronics with IP55 for the wiring compartment, providing strong weather-seal protection against dust and temporary water immersion. The robust construction is engineered for durability under temperature extremes, vibration and outdoor exposure without requiring additional housing. Protections include integrated arc-fault circuit interruption, isolation monitoring and PV rapid shutdown capability.

Pre-shipment inspection checks verify capacity, inverter function, communication integrity and physical condition before dispatch. Every unit is factory-tested and certified so customers receive verified performance data. The stable LFP chemistry combined with active thermal management and high ingress protection minimises weather-related degradation, supporting the full ten-year warranty under normal operating conditions.
