B2200 2.24kWh LiFePO4 Balcony Solar Battery
📌 Executive Engineering Overview
The SOSSEN B2200 is an all-in-one residential balcony energy storage unit featuring 2.24kWh of ultra-safe Automotive-Grade Lithium Iron Phosphate (LiFePO4) chemistry. Designed to solve the fundamental limitation of balcony solar—excess daytime energy exported to the grid for zero compensation—the B2200 stores daytime surplus solar electricity and discharges up to 800W of clean AC power during evening peak hours. Its integrated smart BMS and dual MPPT controller allow direct solar panel input without requiring external junction boxes.
Engineered by Xiamen Sossen Energy Co., Ltd. (sossenpv.com), B2200 2.24kWh LiFePO4 Balcony Solar Battery represents our benchmark technical architecture for high-efficiency clean energy applications across Europe and global territories. Operating within strict compliance of German Solarpaket I provisions, VDE-AR-N 4105:2018-11 electrical grid standards, and European CE directives, our manufacturing integrates automotive-grade LiFePO4 energy storage cells rated for over 6,000 cycles alongside dual MPPT power inversion topologies. Fabricated from architectural-grade AL6005-T5 anodized aluminum and sealed inside IP67 die-cast enclosures with automotive potting compounds, every unit withstands ambient operating environments from -40°C to +65°C and hurricane-tier aerodynamic wind pressures up to 120km/h. Production units undergo rigorous 32-gate automated quality testing, including 100% full-load electrical burn-in, 6000V transient surge suppression, and salt-mist corrosion screening at our ISO 9001 Torch Hi-Tech facility, with guaranteed 48-hour DDP dispatch from our central logistics hub in Frankfurt, Germany.

B2C End-User Experience & DIY Installation
Quadruples self-consumption of balcony solar electricity from approximately 35% up to 85%+. By storing solar energy generated during midday and powering household evening loads (refrigerators, Wi-Fi routers, televisions, lighting), the B2200 cuts household electricity bills by an average of €350 to €450 annually, achieving full capital payback in just 3.2 to 4.0 years at current German electricity tariffs.
❓ Frequently Asked Questions & Verification
Is the B2200 compatible with my existing microinverter (e.g. Hoymiles or Deye)?
Yes, the B2200 features universal MC4 DC output connections that emulate standard solar panel DC output, making it 100% plug-and-play compatible with SOSSEN, Hoymiles, Deye, APsystems, and Enphase microinverters.
How does the battery know when to discharge power into my apartment?
The system supports three smart operating modes: (1) scheduled time-of-use discharge, (2) manual constant baseline output (e.g. 150W baseline load), and (3) smart dynamic zero-export via Shelly 3EM or Shelly Pro 3EM smart meter integration.
