A single B2500 unit offers 1000W dual MPPT solar panel input and 800W DC output. You can expand with up to 2 additional P2500 batters to achieve a total capacity of 6720Wh.

Pairing one B2500 with two P2500s can save you approximately €1200 on your annual electricity bill. By connecting multiple B2500 units, you can increase the total solar panel input and output power (each unit with 1000W PV input, 800W DC output, 2240-6720Wh capacity), allowing you to customize the setup based on your home's needs.

*Note: The B2500 must be used with solar panels and micro inverters to form a complete balcony energy storage system.

Marstek smart meter monitors the total electrical consumption in a household and transmits this data to a device like the B2500. Its main role is to provide real-time information about home energy usage, enabling efficient energy allocation and preventing wastage.

Not designed to allocate power based on individual room needs. Instead, focus on measuring overall energy consumption. The B2500 takes input and output power parameters as predetermined values. The smart meter’s main purpose is to gather real-time data on home energy consumption and relay this information to the B2500 for energy distribution control.

By using the data collected by the smart meter, the B2500 can perform real-time analysis to determine how much power should be supplied to the grid, optimizing energy usage and reducing waste.

By integrating the advanced dual MPPT with a robust 1000W PV Input and 800W DC Output, our system stands as a testament to our commitment to delivering top-notch, dependable power without the fuss.

Experience unmatched compatibility with all MC4 connectors, granting you the freedom to pair with a diverse selection of solar panels and microinverters on the market. Whether you're integrating existing solar equipment or starting anew, the B2500 effortlessly melds with your setup.

The B2500 offers a smooth 15-minute self-DIY solar system setup, ideal for both solar novices and seasoned enthusiasts.

Life is unpredictable, but your energy source shouldn't be. With IP65 water resistance and materials that withstand high temperatures and fire, our product stands as a silent guardian on your balcony. Come rain or shine, scorching heat, or chilly breezes, it remains unwavering, ensuring you're powered up and protected.

Step into the future of energy management with our intelligent app. Offering real-time monitoring, it keeps you informed about your energy consumption and production patterns. But it doesn't stop there.

The app also intelligently calculates your energy savings, giving you a clear picture of your benefits. It's not just about using energy; it's about understanding and optimizing it for a greener tomorrow.
