Check the inverter’s supported battery configuration before installation.

Knox Powerwall 3.1 2.56kWh Battery Capacity

In practice, the Knox Powerwall 3.1 2.56kWh provides nominal storage, whereas usable AC energy depends on discharge limits and inverter efficiency. Therefore, compare battery energy with your actual daily or backup-time load rather than relying on capacity alone.

Understanding the difference between Ah and kWh helps buyers select the correct lithium battery.

• Voltage (V): Represents the battery’s nominal electrical voltage.
• Ampere-hour (Ah): Indicates the battery’s electrical capacity.
• Kilowatt-hour (kWh): Represents the amount of stored electrical energy.

This battery has a nominal voltage of 25.6V and a capacity of 100Ah, giving it a nominal energy rating of 2.56kWh.

Nominal energy is not necessarily the same as usable energy. Actual available energy depends on the permitted depth of discharge, operating conditions, battery settings and system efficiency.

Battery Chemistry and Cycle Life

The Knox Powerwall 3.1 uses LiFePO4 prismatic cells powered by REPT.

Its stated cycle life is more than 6,000 cycles under the following test conditions:

• Temperature: 25°C
• Charging rate: 0.5C
• Discharging rate: 0.5C
• Depth of Discharge: 80%
• End-of-life capacity: 70% of initial capacity

These test conditions are important when evaluating battery cycle life. Actual results can vary depending on temperature, operating current, charging practices and usage patterns.

The designed calendar life is 10 years. This is a design-life figure and should not be confused with the warranty period.

Knox Powerwall Battery Management and Safety

The integrated PACE BMS manages charging and discharging operations while monitoring important battery protection conditions.

Its protection functions include:

• Overvoltage Protection
• Low Voltage Protection
• Overcurrent Protection
• Overtemperature Protection
• Low Temperature Protection
• Short-Circuit Protection

Independent charging and discharging protection helps keep operation within permitted electrical and temperature limits.

The battery also features a touch LCD and PC software for operational monitoring.

Charging and Discharging Performance

Charging and discharging current are important when selecting a battery for a solar inverter.

The Knox Powerwall 3.1 supports:

• Maximum Charging Current: 100A
• Maximum Discharging Current: 100A
• Pulse Discharge Current: 120A for 2 seconds
• Charging Voltage: 27.6–28.8V
• End-of-Discharge Voltage: 22V

The maximum continuous charging and discharging limits should be respected during inverter configuration.

Installers should configure the inverter according to the battery’s supported voltage, current and communication requirements.
