Product description
Product description
The Deye GB-LM4.0-HV is a 4.09 kWh lithium iron phosphate (LFP) battery module, which is the basic unit of the Deye GB energy storage systems. It cannot be used independently, it always requires a controller and base, and depending on the configuration, an inverter.
The modules are installed stacked, with a cable-free connection, which allows for quick and safe installation. A system can consist of a minimum of 2 and a maximum of 6 modules, so the capacity can be adjusted between 8.18 and 24.54 kWh. Multiple stacks can be connected in parallel, so the system can be expanded for larger household or even small commercial use.
The battery module can be used in two types of systems:
- With the combination of GB-LB-BASE controller + GB-S5K–25K-EU inverter , it works as a full-fledged solar energy storage (with PV and grid integration).
- With the GB-LBS-PRO-BASE-HV controller, it can also be operated as a standalone battery stack, without an inverter, and integrated with other EMS systems.
The GB-LM4.0-HV is modularly expandable, making it flexible to meet different energy needs. The LFP cells are safe and have a long lifespan (≥6000 cycles), and the cable-free stacking offers simpler and more reliable installation. Thanks to the IP65 protection, it can be used both indoors and outdoors, so it can be installed in a variety of locations.
Main features:
- Capacity: 4.09 kWh per module (useful ~3.68 kWh, 90% DOD)
- Modular expandability: 2–6 modules/stack (8.18–24.54 kWh)
- Multiple stacks can be paralleled, up to over 100 kWh
- Cell technology: LFP, ≥6000 cycles
- Stackable, cable-free connection
- IP65 protection, indoor/outdoor installation
- Compatible with: GB-LB-BASE (with inverter) and GB-LBS-PRO-BASE-HV (without inverter)

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.
