The Marstek Venus E is a reliable, quiet home battery designed to meet today’s energy needs. With modular expansion, real-time app monitoring, and easy integration into both single-phase and three-phase electrical systems, it’s a flexible energy storage solution that fits your lifestyle and home setup.
Setting up your Marstek battery is simple and fast. Just pick an indoor spot, plug it into a standard wall outlet, and you’re ready to go.
Store solar power or low-cost electricity for later use. The Marstek battery helps you use your energy when it matters most.
Monitor your energy use in real time with the CT002 sensor. It enables smart charging and discharging without relying solely on your smart meter.
Make the most of your solar energy, lower your electricity bills, and take control of your energy independence—right out of the box.
Each Venus E module has a storage capacity of 5.12 kWh, enough to power your evening needs or store extra solar energy. You can connect up to three modules per phase, allowing for up to nine modules total in a three-phase home.
This setup gives you a maximum capacity of over 46 kWh, making it a great fit for both small and large households alike.
By default, the Venus E charges and discharges at 800 watts when plugged into a standard 120V outlet. For higher power needs, you can have it professionally installed on a dedicated circuit, allowing up to 2.5 kW of charging and discharging per module.
This flexibility makes the system suitable for a range of energy needs—from light background consumption to powering active daytime loads.
The Venus E is a plug-and-play system compatible with both single-phase and three-phase electrical setups. Installation is straightforward and can be easily scaled over time by adding more units. For faster charging or discharging needs, professional installation by a certified electrician is recommended.
Thanks to its compact design (approximately 25 x 20 x 9 inches) and low noise levels, the battery is suitable for indoor placement in living rooms, utility rooms, or garages. Each unit weighs around 110 pounds and features durable LiFePO4 battery technology known for long cycle life and excellent thermal stability.
The Marstek mobile app (available for iOS and Android) gives you live insight into your energy use, battery charge levels, and system performance. It offers scheduling, historical data tracking, and remote management—perfect for managing your energy, especially if you have time-of-use electricity rates or solar panels.
In many U.S. homes, smart meter infrastructure varies or may not be available. That’s why the Marstek CT002 energy sensor is a great solution. It clamps onto your main power cables and sends real-time energy data directly to your battery system, independent of smart meters. This enables intelligent battery control and accurate solar surplus detection.
While the Marstek Venus E is mainly designed for daily energy optimization, it also offers basic backup power capabilities. When plugged into a standard outlet, the battery provides power through a single socket only.
For more advanced backup, you can have the system professionally installed on a dedicated circuit. This setup allows the battery to automatically supply power to that entire circuit during a power outage, keeping multiple essential devices running.
Backup capability depends on your specific setup and may require a compatible inverter, dedicated backup outlet, or smart switch. Our team is here to help you plan and configure this feature during installation.
The Venus E is perfect for homeowners seeking greater energy independence without the hassle of a large, complex installation. Whether you already have solar panels or plan to install them, this battery lets you store your own power and use it when it’s most valuable.
It’s especially suited for households with time-of-use electricity rates, charging during low-cost nighttime hours and discharging during expensive peak periods. Thanks to its modular design and easy setup, the Venus E is also a great fit for renters, smaller homes, or anyone who values plug-and-play convenience with room to grow.
