Marstek Venus All-In-One 5.12kWh 2.0+ Energy Storage

Including P1 Meter (CT003), CT Sensor (CT002) & Wall Mount

The Marstek Venus 5.12kWh Home Battery is a smart all-in-one energy storage solution, designed for households aiming to reduce grid dependence. Built with safe and long-lasting LiFePO₄ technology, the battery connects directly to a standard 230V power outlet – no installer, no inverter, no tools required.

💡 New: Includes universal wall mounting bracket (non-original Marstek)
In addition to the standard swivel wheels, this version includes a universal wall mount bracket for vertical installation. This is ideal for tight indoor spaces or outdoor setups. Please note: the wall mount is not manufactured by Marstek and will protrude a few centimeters on each side.

📦 Available from stock – installation in under 10 minutes.

📊 P1 & CT: Smart Grid Communication

🔌 CT003 – P1 Meter for modern smart meters (SMR5.0 or higher)

This meter plugs directly into the P1 port of your digital smart meter, enabling live monitoring of grid import/export. Works seamlessly with the EMS feature for automated optimization.

⚡ CT002 – Clamp sensor for older or non-digital meters

For homes without a P1-compatible meter, the CT002 measures consumption via current induction around your main power cable. This ensures compatibility with legacy or analog meters.

🔧 Only one of the two sensors is needed, depending on your setup. The system will automatically detect the active sensor.

• Monitor battery level and power usage in real time

• Automatically optimize charging/discharging cycles

• EMS (Energy Management System) adjusts to market prices and usage patterns

• Receive updates and alerts directly through the Marstek app

🌱 Safe, Durable Design
