Key Features & Benefits

🔋 2.4kWh Base Capacity, Expandable to 9.6kWh

Start with a robust 2.4kWh of storage, perfect for evening and overnight power needs. As your energy demands grow, seamlessly add Sunpura B2400 expansion modules to scale your system up to a massive 9.6kWh.

⚡ Dual MPPT Solar Inputs (2000W Max)

Equipped with two independent MPPT trackers, the S2400 can connect directly to compatible solar panels (up to 1000Wp per input). This allows for flexible panel orientations (e.g., East/West roofs) to maximise energy harvest throughout the day. It can also be AC-coupled to existing solar installations.

🛡️ Premium LiFePO₄ Battery Technology

Built for safety and longevity. The advanced Lithium Iron Phosphate (LiFePO₄) cells deliver 8,000+ charge cycles (to 70% State of Health), translating to a 10–15 year lifespan. It also features an integrated aerosol fire-suppression system and smart BMS for ultimate peace of mind.

🔌 Dedicated 2400W Backup Output

Don’t let power cuts disrupt your life. The S2400 features a dedicated off-grid backup output capable of delivering 2,400W continuous power (3,600W surge for 5 seconds), keeping your Wi-Fi router, lighting, fridge, and essential devices running when the grid goes down.

🌧️ IP65 Weather Resistance

Designed for flexibility. The durable, robust enclosure is IP65-rated, making it suitable for installation in garages, utility rooms, or sheltered outdoor locations.

📱 Smart Energy Management & App Control

Take control of your energy. The Sunpura app provides real-time monitoring of solar generation, battery status, and household consumption. It seamlessly integrates with Smart Meters, Smart Plugs, and dynamic tariffs (like Octopus Agile or Intelligent Go) to automatically charge when electricity is cheap and discharge when prices peak.
