Product description
Product description
The Deye SE-G5.1PRO-B series is an advanced energy storage system based on lithium iron phosphate (LFP) technology. It is designed for home and commercial applications where a reliable, long-lasting and expandable battery solution is required.
Available versions:
- Deye SE-G5.1PRO-B – 5.12 kWh
- Deye SE-G5.1PRO-B – 10.24 kWh
- Deye SE-G5.1PRO-B – 15.36 kWh
- Deye SE-G5.1PRO-B – 20.48 kWh
The SE-G5.1PRO-B battery has a modular design, so the capacity can be increased by connecting multiple units – up to 327 kWh, with a total of 64 batteries operating in parallel. This allows the system to be flexibly adapted to suit everything from small households to larger commercial projects.
The built-in BMS (Battery Management System) continuously monitors and balances the cells, optimizing charging and discharging. This increases the battery life and ensures safe operation. The system supports remote monitoring and software updates, making maintenance simple and fast.
Deye batteries use cobalt-free LFP cells, which are safe, non-flammable and environmentally friendly. The modules are naturally cooled and operate over a wide temperature range of -20°C to +55°C. The compact, 19” standard design offers multiple mounting options: wall, rack or floor mounted.

How do I choose the right battery?
How do I choose the right battery?
The most important thing is that the battery fits your inverter and the performance of your system. It is worth considering how much capacity (kWh) you need and whether you want to expand the system later.
Always check the inverter's technical data sheet, as it will tell you which batteries it is compatible with. For example, Huawei inverters only work with Huawei batteries, while Deye inverters can be connected to multiple manufacturers, offering a more flexible solution.
How do inverter types differ?
How do inverter types differ?
The lifespan of modern lithium batteries is usually 10–15 years, depending on usage and temperature conditions.
Manufacturers typically give an expected lifespan of 6,000–8,000 charging cycles – this can mean up to a decade and a half, assuming one cycle per day.
What happens in the event of a power outage?
What happens in the event of a power outage?
If the inverter supports backup (stand-alone) operation, it will automatically switch to the battery during a power outage, so the most important consumers continue to operate.
It is important to know that if there is no backup function, the system will completely stop in the event of a power outage, even if the solar panels are producing. This is because most on-grid inverters cannot operate without mains voltage for safety reasons, so they cannot supply power or charge batteries.
What warranty does the battery have?
What warranty does the battery have?
Depending on the manufacturer, batteries come with a 5 or 10 year warranty, and for some models this is also tied to the number of cycles. We indicate the exact warranty period on each product page, so you can always see how long the manufacturer's warranty lasts before you buy.
What happens if the battery fails?
What happens if the battery fails?
If the battery is not working properly, it is a good idea to first have the problem diagnosed by a professional to rule out incorrect setup or installation. It is possible that the problem is not with the battery itself, but with a non-activated function or communication setting.
If it is proven that there is indeed a problem with the product, you should contact the manufacturer's or distributor's customer service, who will assist you in the troubleshooting process and the warranty administration process.
