Description

Deye AI-W5.1-B - 5.12kWh Low-Voltage Battery Module – The perfect solution to expand your existing storage system flexibly and future-proof. When your electricity needs grow – for example due to purchasing an electric vehicle or installing a heat pump – this module simply grows with you. With its advanced, completely cobalt-free Lithium Iron Phosphate technology (LiFePO4), this single module guarantees not only the highest fire safety in your home, but also an extremely long service life and consistent performance.

The strongest benefits for your home

Effortless installation: Thanks to the revolutionary plug-in design, this additional module is simply placed on top of your existing battery tower. The units connect completely automatically, which prevents annoying cable clutter and dramatically speeds up assembly.
High capacity: With an additional 5.12 kilowatt-hours per module, you massively increase your energy reserves and secure even more valuable solar power for the long evening hours.
Intelligent protection: The smart Battery Management System (BMS) integrates seamlessly into your existing storage system and monitors every single cell to fully automatically protect the overall system from overcharging or harmful deep discharge.

Smart control for your electricity costs

Save money permanently by making optimal use of your photovoltaic system. The more of your own electricity you can store, the less expensive energy you need to purchase from the public grid. In combination with your tower system, this battery module intelligently ensures that your valuable energy is available in your home exactly when you need it. In addition, expanding your capacity supports the reliability of your backup power supply: in the event of an unforeseen power outage, the additional module gives you even more reserves to keep your most important household devices running smoothly for many hours.
