Deye Complete Off-Grid Solar & Battery System

Deye AI-W5.1B Stackable Battery (5.12kWh) – Modular LiFePO₄ Energy Storage

Premium low-voltage (51.2V) LiFePO₄ battery modules designed to scale from a small home system to large storage banks. Now also available with solar panel configurations in 2.38kWh, 4.75kWh, 5.70kWh, 7.6kWh, 8.55kWh, 9.50kWh & 11.4kWh options. Built tough for Australian conditions, with clean installs and future expandability.

✅ CEC Approved ☀️ Solar Panels Included 🔋 5.12kWh per module 🧱 1–6 modules per stack (30.72kWh) ➕ Up to 6 stacks in parallel 🌧️ IP65 indoor/outdoor 🛡️ 10-Year warranty

Overview

The Deye AI-W5.1B is a modular (LFP) LiFePO₄ battery solution that lets you start with one module and grow capacity over time. LFP chemistry is known for safety and long service life, while the stackable format keeps the system neat and installer-friendly.

This package also includes solar panel configuration options in 2.38kWh, 4.75kWh, 5.70kWh, 7.6kWh, 8.55kWh, 9.50kWh & 11.4kWh to match your energy requirements.

Per-module energy
5.12kWh (Nominal)
Chemistry
LiFePO₄ (LFP)
Stack Capacity
Up to 30.72kWh
Ingress Rating
IP65

Key Benefits

  • Modular scalability: add modules now or later as your loads grow
  • Solar panel options included: available in multiple kWh configurations
  • Clean installs: stackable system reduces clutter and complexity
  • Built tough: IP65 rating for indoor/outdoor installs
  • Long life: ≥ 6000 cycles to 70% end-of-life capacity
  • Rebate-ready: CEC approved battery model (program rules apply)

What we’re known for: practical advice and real after-sales support (so you’re not left guessing after purchase).

Available Solar Panel Configurations

  • 2.38kWh Solar Panel Configuration
  • 4.75kWh Solar Panel Configuration
  • 5.70kWh Solar Panel Configuration
  • 7.6kWh Solar Panel Configuration
  • 8.55kWh Solar Panel Configuration
  • 9.50kWh Solar Panel Configuration
  • 11.4kWh Solar Panel Configuration

Solar panel quantity and configuration vary depending on the selected kWh option.

Modular Expansion (Verified)

The AI-W5.1B system scales in two ways:
