The Jupiter C stores the solar energy generated by the solar panels and feeds it into the grid via a built-in micro-inverter. The maximum solar input power is 2000 W. The grid output is 800 W, which can be adjusted manually or automatically according to the smart meter. How can I control the output of the Jupiter C ? You can manually adjust the discharge time and power via the Jupiter's HD touchscreen or by adding the Jupiter to the Marsrtek app. Alternatively, you can select the automatic discharge mode when pairing it with a smart meter. The Jupiter will then discharge according to your discharge settings or based on data collected by the smart meter. Which smart meters are compatible with the Jupiter C ? Currently, Jupiter supports the Marstek Smart Meter CT002 and Shelly pro 3em. If you are using a P1 meter, the Marstek CT003 can be used with it for smart power distribution. Can the capacity of the Jupiter C be expanded? The Jupiter C has a capacity of 2,56 kWh and can be connected to a maximum of 3 expansion batteries. The capacity range is therefore 2,56 kWh to 10,24 kWh. Can the Jupiter C expansion battery increase the capacity of the Jupiter All-in-One C/E? The Jupiter C expansion battery does not support capacity expansion for the Jupiter All-in-One C/E. What do I need to consider when using the Jupiter C in winter? At low temperatures, the activity of lithium batteries decreases, which can easily lead to rapid and high battery consumption. Therefore, care should be taken when using batteries in winter: (1) In winter, it is recommended to reserve at least 30% or 50% of the battery power to avoid low battery performance. Especially in snowy weather, it is recommended to maintain 70% of the battery capacity to ensure that the battery has sufficient reserves. (2) If the battery has not been charged for more than one week, it is recommended to interrupt the discharge until the battery is more than 90% charged before discharging is started. (3) Avoid high-power discharges. PV power is weaker in winter and charging is more difficult. High-power discharges can easily lead to the battery having low power for an extended period. (4) Check regularly whether the PV panels are able to supply power normally. Especially after heavy snowfall, the PV panels can easily be blocked by snow and may not be able to charge the battery for a long time.   Legal information Liability The projected annual electricity cost savings of about 1.109 € The Marstek Jupiter C Plus is based on a model-based estimate taking into account the following parameters and assumptions: 1. Calculation principles System parameters: 2,4 kWp maximum photovoltaic input power, 12,24 kWh maximum storage capacity, bidirectional inverter (limited to 800 W continuous power). Scenario assumptions (reference values ​​2025/2026): 1.200 hours of sunshine per year (average for Central Germany), €0,40/kWh average household electricity price (incl. taxes and levies). Efficiencies: Inverter efficiency 99,8%, storage efficiency (LFP technology) 96,5%. 2. Formula and calculation The savings are calculated by multiplying the usable, self-generated solar power by the current electricity price: Theoretical generation: 2,4 kW × 1.200 h = 2.880 kWh/year. Usable solar power: 2.880 kWh × 0,998 × 0,965 = 2.773,64 kWh / year. Annual savings: 2.773,64 kWh × €0,40/kWh ≈ €1.109. 3. Important note regarding variability Actual yields may vary. Key influencing factors include geographical location (e.g., 1.300 hours in southern Germany vs. 1.000 hours in the north), the orientation and tilt of the PV modules, local shading, fluctuating electricity market prices, and the household's individual consumption patterns. This calculation is for guidance only and does not constitute a contractual yield guarantee or legal warranty. Legal notice (Germany) In order to benefit from the simplified regulations for plug-and-play generation plants according to Section 8 Paragraph 5a EEG To benefit, the following limits apply: The total installed PV capacity must not exceed 2.000 Wp be. The inverter apparent power must ≤ 800 VA . Should your system exceed these limits, the network operator's standard requirements will apply. This may include, among other things, extended registration, meter modification, or formal approval procedures. Please familiarize yourself with the locally applicable regulations before installation. Registration & Installation: Plug & Play solar systems can generally be installed and connected independently in Germany. Registration in the Market Master Data Register (MaStR) Registration is legally required (www.marktstammdatenregister.de). The registration process with the grid operator has been significantly simplified and partially automated by the Solar Package I.
