Marstek Venus 2.0 vs Venus 3.0 – Which One to Choose?

🔋 Capacity & Technology (same for both)

• LiFePO₄ cells, lifespan > 6000 cycles (~10–15 years)

• Gross capacity: 5.12 kWh

• Nominal voltage: 51.2 V

• AC charge/discharge power: standard ±800 W, expandable to 2500 W (via dedicated circuit)

🌱 Installation & Use

• Both models are Plug & Play via standard 230 V outlet

• IP65 housing: suitable for indoor and outdoor use

• The 3.0 is easier to install due to its lighter weight and built-in handles

⚙️ Electronics & Connectivity

✅ Summary

Venus 3.0 compared to the 2.0 offers:

• A more compact and lighter design

• Integrated side handles

• LAN port for more stable network connections

• Up to 5% faster charging and discharging

Venus 2.0 is still a solid choice, but is slightly larger and heavier, and requires extra installation steps (e.g., attaching the handles).
