Description

Deye SE-G5.1 Pro-B – your reliable partner for a future-proof and independent power supply. With this robust low-voltage battery storage, you take the decisive step toward massively reducing your expensive grid consumption. This battery storage was specifically developed to combine maximum safety, longevity, and particularly fast payback. Thanks to its outstanding IP65 rating, this model is extremely resistant to external influences and gives you maximum flexibility in choosing the installation location. Store surplus solar energy during the day and use it exactly when you need it in the evening and at night.

Your Key Benefits at a Glance

Safe cell chemistry: The cobalt-free lithium iron phosphate technology (LiFePO4) guarantees absolute thermal stability and virtually eliminates the risk of fire.
Extreme IP65 protection: The sealed housing effectively protects the sensitive electronics from dust and water jets – ideal for demanding environments.
Seamless scalability: The system grows with your needs. By simply connecting multiple units in parallel, you can flexibly expand your storage capacity at any time.
Intelligent BMS: The integrated battery management system continuously monitors voltage, current, and temperature to protect the battery from overcharging or deep discharge.
Outstanding price-performance ratio: As a classic top performer in its segment, this battery storage ensures your investment pays off in the shortest possible time.

Smart Energy Management for Your Everyday Life

With the Deye battery storage, you finally get to use the electricity you produce yourself on your roof. Instead of feeding valuable energy cheaply into the public grid, the system stores every surplus ray of sunshine in its powerful cells. As soon as the sun sets or demand in the house increases, the battery storage delivers the energy instantly and with minimal loss. This means your electricity bill shrinks noticeably, and you're no longer at the mercy of constant price fluctuations from electricity providers. Combined with a suitable hybrid inverter, you're also optimally prepared for power outages, as the system can supply critical household devices with backup power in a flash. This gives you the reassuring feeling of always being well supplied.
