Key Features:

Plug & Play, Installation in 15 Minutes

Say goodbye to complex setups and costly electrician visits. The B2500-D is built with a user-first design philosophy, allowing effortless installation in just 15 minutes—no tools, no wiring expertise required. By eliminating unnecessary complications and focusing on core functionality, this system delivers a seamless, plug-and-play experience that fits perfectly into modern lifestyles.

Flexible Expansion of Capacity and PV Input

Designed for flexible scalability—multiple units can be connected to expand both energy storage capacity and PV input. For instance, when paired with a dual-MPPT 800W on-grid microinverter, you can link up to four B2500-D units, reaching a total of 8.96 kWh storage and 4800W PV input. This modular design provides robust performance from day one, while allowing your system to grow with your energy needs over time.

Max. 1600W PV Input & 800W Output

Equipped with advanced dual MPPT technology, the system supports a powerful 1600W PV input and delivers up to 800W DC output, ensuring efficient and reliable energy management. This design reflects our commitment to providing high-performance power solutions—without the complexity.

Intelligent power distribution by smart meter

The Marstek Smart Meter continuously monitors your household’s total energy consumption and transmits real-time data to the B2500. Leveraging this information, the B2500 performs intelligent analysis to optimize energy distribution, determining the precise amount of power to feed into the grid. This results in smarter energy management, reduced waste, and enhanced overall system efficiency.

Smart App Control & Monitor

Step into the future of energy management with our intuitive smart app. Providing real-time monitoring, it keeps you fully informed about your energy consumption and production patterns. Beyond tracking, the app intelligently calculates your energy savings, giving you clear insights into your environmental and financial benefits. It’s more than energy use—it’s about understanding, optimizing, and maximizing efficiency for a sustainable future.

IP65 Waterproof & 10 Years Warranty

Life is unpredictable, but your energy supply shouldn’t be. Featuring IP65 water resistance and built with durable, fire-resistant materials, our system acts as a reliable guardian on your balcony. Rain or shine, extreme heat or cold, it stands strong—delivering consistent power and protection no matter the conditions.
