Download Product Datasheet

Product Overview Knox Powerwall 6.11:

This is a 51.2V LiFePO₄ wall-mounted battery designed for:

• Home solar storage

• Hybrid inverter backup

• Commercial/industrial UPS-style use

The main model shown is:

51.2V 100Ah = ~5.12 kWh

Key Features:

1. High Energy Density

More storage in a compact wall-mounted box — good for indoor installs.

2. Long Cycle Life

Advertised:

• 6000 cycles @ 80% DoD
  That’s solid. In real life, that can mean 10–15 years depending on usage.

3. High Charge/Discharge Rate

• Up to 1C–1.5C

For the 100Ah model:

• 1C = 100A

• 1.5C = 150A peak

Meaning it can support high-load appliances better than weak batteries.

4. Built-in Smart BMS

Includes:

• Cell balancing

• Overcharge / overdischarge protection

• Temperature and short-circuit safety

This is essential for lithium systems.

5. Efficiency >95%

Very normal for LiFePO₄ — good for solar storage.

6. IP54 Protection

This is actually better than many indoor-only batteries.

• Protected from dust + water splashes
  Useful in garages, utility rooms, and humid climates.

7. 4.3” Touch Display

Nice bonus for monitoring:

• SOC (battery %)

• Voltage/current

• Errors/alarms

8. Modular Expandable Design

Can connect multiple packs in parallel.

Poster says:

• Up to 8 units parallel

So max storage:

• 8 × 5.12 kWh = 40.96 kWh
