Stand-Out Advantages of the Jupiter E Balcony Solar System
5-Minute Plug-and-Play Setup
Skip the complex technical hassle and expensive installation fees. Simply unpack the Jupiter E balcony solar system, connect the standard MC4 solar inputs, and you are ready to go. The entire system installs in under 5 minutes.
High-Efficiency Solar Input Capability
Equipped with four independent MPPT channels, the Jupiter E supports up to 2000W of solar input. This maximises your daily energy harvesting, even in the UK’s unpredictable weather conditions.
Ample Home Battery Storage
Featuring a massive 5120Wh (5.12 kWh) LiFePO₄ battery capacity, the Jupiter E doubles the storage of the Jupiter C model, offering significantly longer autonomy and overnight power security.
Weather-Resistant IP65 Design for UK Climates
The robust IP65 rating ensures complete resistance against dust, rain, and harsh weather. This makes it the ideal durable choice for outdoor installation on balconies, patios, or gardens.
Long-Lasting LiFePO₄ Battery Life
Built on premium LiFePO₄ chemistry, the battery delivers over 6,000 charge cycles to 80% capacity. This translates to a decade or more of reliable, daily clean energy.
Smart, Silent, and Fan-less Operation
Monitor and manage your home energy ecosystem via the built-in HD touchscreen or the dedicated Marstek app (available via Wi-Fi and Bluetooth). The fan-less, convection-cooled design operates in complete silence.
Intelligent Power Control & Smart Meter Compatibility
Pair the system with compatible smart meters—including the Marstek CT002, CT003, or Shelly 3 Pro EM—to automatically adjust battery discharge based on your home’s real-time demand, completely avoiding costly grid feed-in.
