MARSTEK B2500-D – Balcony Power Station Storage 2240Wh

MARSTEK B2500-D – Smart Balcony Storage with 2240Wh

The MARSTEK B2500-D is a powerful and flexibly expandable energy storage system for your balcony power plant. With 2240Wh capacity, IP65 protection, and over 6000 charging cycles, it is the ideal solution for a future-proof energy supply at home.

Flexible Expansion of Capacity and PV Input

By connecting multiple MARSTEK B2500-D units, you can flexibly expand the capacity and PV input of your balcony power plant. For example, with a 2 MPPT 800W on-grid microinverter, you can connect up to four B2500-D units with a total capacity of 8.96 kWh and a PV input of 4800W.

Intelligent Energy Distribution via Smart Meter

The MARSTEK Smart Meter monitors the entire household power consumption and transmits this data to the B2500. This allows the storage system to analyze in real-time how much power should be fed into the grid – for maximum efficiency and minimal waste.

App Control from Anywhere

With the intelligent MARSTEK App, you can keep an eye on your energy consumption and production at all times. The app automatically calculates your energy savings and gives you a clear overview of your benefits.

Compatible with 99% of all Microinverters

Thanks to MC4 connectors, the B2500 is compatible with almost all common microinverters and solar modules – for maximum flexibility when integrating it into your existing system.

IP65 – Water and Dust Protected

With IP65 protection, the B2500 is ideally suited for outdoor use on the balcony – reliable in rain, heat, and cold.

6000+ Charging Cycles – LiFePO4 Technology

The LiFePO4 (Lithium Iron Phosphate) cells offer over 6000 charging cycles up to 80% capacity and a 7-stage safety protection function (OVP, UVP, OCP, SCP, OTP, UTP) for maximum safety and longevity.

10-Year Warranty

The MARSTEK B2500-D comes with a 10-year manufacturer's warranty – for worry-free operation for many years.
