1. Plug-and-play for everyone: Easy installation

Both systems rely on AC coupling and a user-friendly Plug and play installation via a conventional socket – ideal for tenants and DIY enthusiasts. No electrician is required. Zendure SolarFlow 2400 AC aims at rapid integration into existing PV systems, including rooftop systems, the Marstek Venus E primarily to users of balcony power plants and smaller households.

2. Storage capacity and scalability: If you want more, you get more

• Zendure SolarFlow 2400 AC: Starts with 2,88 kWh and can be modular up to 17,28 kWh expand – a real advantage for growing energy needs.

• Marstek Venus E: Comes standard with 5,12 kWh and is also expandable – up to 20,48 kWh through the parallel operation of four devices.

Both systems use durable LiFePO₄ batterieswhich ensure safety and a service life of over 6000 charging cycles.

3. Intelligent energy management: AI meets power-saving logic

A highlight of SolarFlow 2400 AC is the integrated ZENKI Energy Management System, which uses AI to analyze weather data, electricity prices, and consumption patterns to optimize energy flow. According to the manufacturer, save up to 42% on electricity costs.

Also the Marstek Venus E scores with intelligent control: A smart meter automatically detects excess energy and stores it for later. The system also supports dynamic electricity tariffs from up to 46 countries, which offers clear advantages when prices fluctuate.

4. Emergency power capability: Just in case

Here the advantage clearly lies with Marstek Venus E: Thanks to an integrated Emergency power function with 2500 W In the event of a power outage, important devices such as refrigerators or routers can continue to operate – a plus for households with higher security needs.

The SolarFlow 2400 AC does not offer an integrated emergency power function, but focuses more on efficiency during regular operation.
