Discover Jupiter C Plus – Compact all-in-one storage for balcony power plants

A key feature of the Jupiter C Plus is the Anti-feedback technology, which in combination with a compatible smart meter – such as the Marstek CT002, Shelly Pro 3EM or HomeWizard P1 – enables the electricity generated to be used specifically in the household without being fed into the public grid.

This function is particularly relevant for users who want to stay within the 800 W feed-in limit or who deliberately forgo feed-in tariffs in order to maximize self-consumption.

Smart Meter CT002: Precise measurement, fast response

The Marstek CT002 was developed for three-phase consumption measurement and is compatible with various Marstek devices, including the series JUPITER, VENUS and SATURN. Technical features include:

• Three-phase measurement with ±1% accuracy

• Bluetooth and WiFi connectivity

• Response time under 10 seconds

• Mounting on top hat rail (DIN rail), installation by qualified personnel recommended

The app allows you to track the power flow in real time. Some users also report stable integration without the need for additional systems.

Installing the Jupiter C Plus – Plug & Play in just a few steps

The Jupiter C Plus is put into operation using a simple plug-and-play concept:

1. Place on a stable surface (e.g. concrete, stone)

2. Connection of the PV modules via MC4 cables (up to four MPPT inputs available)

3. Connection to the home network via the supplied AC cable

4. Turn on and pair the app

Weighing around 28kg The device is relatively easy to handle, and its compact housing (480 × 320 × 230 mm) makes it suitable for smaller areas such as balconies or garage corners.

Marstek App & Control – How the Jupiter C Plus works in everyday life

The associated one Marstek App (Android/iOS) enables convenient management:

• Select region “Europe”

• Connection via QR code or Bluetooth

• WLAN configuration

• Display of battery level, solar production, consumption in real time

• Basic settings and device management

The app is functional and covers the essential requirements for daily use.

Modular storage expansion – up to 10,24 kWh

The Jupiter C Plus can be extended with separately available expansion modules from 2,56 kWh to up to 10,24 kWh Each module uses LiFePO₄ cells with a service life of over 6.000 charge cycles (up to 80% remaining capacity) and is automatically detected and integrated – without any additional configuration.

The modular concept offers flexible adaptation to growing energy needs, for example when upgrading the PV system or when household electricity consumption increases.

Integration of the smart meter in the Jupiter C Plus – quick & easy

The connection between the storage unit and the smart meter is established via the same Wi-Fi network and usually takes only a few minutes:

1. Current sensors of the CT002 connect to the three phases

2. Enable Bluetooth search in the app

3. Pair device and apply settings

If you have connection problems, we recommend restarting the app or looking at the manufacturer's official instructions or video tutorials.

Conclusion

Compact, smart, independent: The Jupiter C Plus is yours Plug-&-Play balcony power plant storage with Anti-feed, MPPT technology and up to 10,24 kWh LiFePO₄ power – for genuine self-consumption without detours.
