Description

Deye RW-M6.1-B – this is your reliable partner when it comes to regaining full control over your electricity costs. At a time when feeding solar power into the grid barely pays off anymore, maximizing your own consumption is the only path to real economic efficiency. This state-of-the-art low-voltage battery storage stores your surplus solar power during the day with extremely low losses, so you can run your own devices in the evening and at night. The result is a massive reduction in the electricity you draw from the public grid and a reassuring sense of security for your home.

The Strongest Benefits for Your Home

Maximum safety through LFP technology: The battery storage relies on cobalt-free lithium iron phosphate cells. This cell chemistry is considered the safest and most thermally stable on the market, effectively preventing overheating.
Future-proof flexibility: Will your electricity demand grow in the future due to an electric car or a heat pump? No problem. The system can be easily expanded by connecting up to 32 units in parallel.
Intelligent protection mechanism: A smart battery management system (BMS) continuously monitors every single cell and reliably protects the battery from overcharging, deep discharge, and short circuits.
Additional physical safety: A mechanically triggered 125A circuit breaker is directly integrated into the unit and safely disconnects the system in the event of extreme loads.

Comprehensive Energy Management Made Simple

The smart battery storage thinks ahead for you. The integrated software communicates seamlessly with your inverter and decides in a fraction of a second where the power needs to flow. You can even set the battery to charge during periods of low electricity tariffs and use the stored energy only when grid electricity is particularly expensive. In addition, the architecture provides an excellent foundation in the event of a power outage: in combination with a compatible hybrid inverter, the battery storage can seamlessly continue to supply backup power to critical loads such as the refrigerator or the internet, so you're never left in the dark. That's energy management that delivers real, tangible added value in your everyday life.
