What is the Marstek Venus E?

The Marstek Venus E is an innovative AC-coupled energy storage system with a capacity of 5.12 kWh that stores surplus solar power and maximizes self-consumption. With plug-and-play installation, emergency power supply, and dynamic tariff utilization, it is an ideal solution for renters and households looking to reduce their energy costs and increase their independence.

What exactly is the Marstek Venus E?

The Marstek Venus E is a compact all-in-one AC storage system specifically designed for balcony power plants and smaller PV systems. With a LiFePO4 battery, the storage unit stores surplus solar power or inexpensive grid power and releases it as needed. Easy installation and app control make it a flexible solution for households and renters who want to optimize their energy efficiency.

This storage system detects surplus power via a smart meter and stores it efficiently to increase self-consumption. The IP65 protection allows for both indoor and outdoor use, with app control offering intelligent optimization for dynamic tariffs.

How does the Marstek Venus E work?

The Marstek Venus E operates efficiently by storing surplus solar power or inexpensive grid power and releasing it during high consumption or power outages. The storage unit automatically detects surplus power and discharges as needed, controlled via an app and a smart meter. The AI mode analyzes consumption data, weather forecasts, and electricity prices to achieve optimal savings.

In AI mode, it continuously analyzes consumption patterns, weather data, and tariff information to maximize savings. The storage unit can also be manually set or switched to "self-consumption" mode to optimize power consumption. Zero injection prevents electricity from being fed back into the grid, while the emergency power supply is activated in just 20 milliseconds.

What advantages does the Marstek Venus E offer?

The Marstek Venus E offers numerous advantages for households looking to reduce their energy costs and increase their energy self-sufficiency. Key benefits include:

• Savings of up to €1600 annually through self-consumption and dynamic tariffs

• Emergency power function for an uninterrupted energy supply during power outages

• High efficiency of more than 93.5% and a durable LiFePO4 battery

• Flexible expandability, achieving a total output of 20.48 kWh with up to four devices

• Easy installation without an electrician thanks to plug-and-play technology

• Compatibility with third-party smart meters like Shelly Pro 3EM

• Mobility and flexibility, especially suitable for renters

How to install the Marstek Venus E?

Installing the Marstek Venus E is incredibly simple and does not require an electrician. Simply plug the storage unit into a household outlet, install the smart meter, and connect the storage unit to the app. Within minutes, the system is ready to operate and automatically optimizes your electricity consumption.

For outdoor use, it is recommended to mount the storage unit either on the wall or on the floor, with stable positioning being crucial. For full utilization of the app functions, a specialist should be consulted for the installation of the smart meter.

Is the Marstek Venus E emergency power compatible?

Yes, the Marstek Venus E is emergency power compatible and can deliver up to 2500 W of power. This means it can seamlessly supply power to important appliances such as refrigerators, lighting, and routers in the event of a power outage. The switch to emergency power occurs in just 20 milliseconds, ensuring no noticeable interruption.

The emergency power function is particularly valuable for households that depend on a continuous energy supply, such as during power outages or in areas with an unstable power supply. This ensures that important devices always remain operational.

Can the Marstek Venus E be expanded?

Yes, the Marstek Venus E can be connected in parallel with up to 4 units, allowing for a total capacity of up to 20.48 kWh. This expandability is particularly useful when energy demand increases or larger PV systems are to be operated.

The app controls multiple devices simultaneously, allowing you to manage energy distribution efficiently. However, when expanding the system, it is important to ensure that the capacity of the household connection is sufficient to supply the additional devices.

What are the app functions of the Marstek Venus E?

The Marstek Venus E offers a variety of functions via its associated app. Key functions include:

• Real-time monitoring of energy consumption

• AI optimization to maximize savings

• Control of mode changes and dynamic tariff utilization

• Integration of Modbus for smart home control

• Visualization of energy flows and schedule control

These functions enable simple and user-friendly management of the energy storage system, so you always have an overview of your energy consumption and associated costs.
