Launching the Marstek Jupiter C Plus: the latest expandable storage system for plugin solar installations

We present the new Marstek Jupiter C Plus storage system, with a base capacity of 2,56 kWh, expandable up to 10,24 kWh. An ideal solution to make the most of solar production this summer and increase your savings for many years to come.

Produce during the day and consume also at night

The Marstek Jupiter C Plus features a modular storage capacity expandable to over 10 kWh, in an all-in-one plugin system that integrates a microinverter and control unit. It also includes a monitoring touchscreen to view your solar production in real time on the device itself, no smartphone and app needed.

Connect up to 4 of our high-end solar panels directly to the Storage and connect it to a standard socket in your home. With its 4 MPPTs, input capacity of up to 2.400 W and output of 800 W, you can generate and store energy efficiently, maximizing your savings.

Thanks to the smart meter and mobile app, the system detects when your kit is feeding energy into the grid and activates the zero feed-in system, automatically storing the energy and avoiding wasted production.

Expand your storage

The new Marstek Jupiter C Plus has a stackable and expandable storage design, where the master battery comes with an integrated microinverter, controller, and display.

This battery starts with a base capacity of 2,56 kWh and can be expanded with up to 3 additional 2,56 kWh expansion batteries, easily stacked one on top of the other to reach a total of 10,24 kWh.

One of the best investments in solar storage

Based on our calculations of storage capacity price per kWh, the new Marstek Jupiter C Plus ranks among the most cost-effective options in our entire catalog, at just €268 per kWh.
It not only helps you save during the day with solar production and at night with stored surplus energy, but also offers savings from day one, thanks to one of the most affordable prices among storage systems.

Add the panel pack for maximum production

To make the most of the expandable storage capacity of the new Marstek Jupiter C Plus, you need a set of high-end panels that can produce the energy required for your daily consumption and provide backup power at night.

That’s why we created the new Robinsun Panel Pack, a set of solar panels and mounting systems specially designed for all-in-one batteries, where the microinverter is already integrated.

You can choose between 2, 4, or 8 panels, depending on your storage system or your household consumption, and select the panel type and mounting option that best suits your needs. This pack is compatible with the Marstek Jupiter C Plus and all other all-in-one storage systems we sell on Robinsun, as well as our solar boilers.

Under ideal conditions, for example, in southern Europe with good orientation and tilt, a pack of 4 panels (each between 450-470 W) can generate around 7 kWh per day. This allows the battery to be fully charged before the end of the day, in addition to covering direct consumption during the day. The energy stored can cover most if not all night consumption for the vast majority of households.

This combination creates an efficient solar system that maximizes daily savings, providing energy during the day and backup power for the night.

Monitoring and control

The Marstek app allows you to remotely monitor the battery status in real time. It also lets you customize the battery’s operating mode and manually adjust output time and power, making energy management efficient and flexible.

The HD touchscreen offers a clear and user-friendly interface, significantly improving the user experience with intuitive and convenient interaction.

Warranty, quality, and peace of mind

Like all products from the renowned Marstek brand, the new Jupiter C Plus uses LiFePO₄ cell technology, known for its high safety and efficiency standards.

Specifications:

• 6.000 cycle warranty (16 years of daily use)
• 10-year product warranty
• IP65 rating for outdoor use
• Operating temperature: -20 ℃ to +60 ℃

With this new technology, we continue expanding the range of options so you can choose the kit with panels, mountings, and storage systems that best suit your needs.
