Product description
Product description
The Sofar BTS 5K-BDU is the central control unit for BTS 5K battery modules, providing cell-level monitoring, control of charging and discharging processes, and communication with inverters.
One BDU can connect 1 to 4 BTS 5K modules, giving a total system capacity of 5.12 kWh to 20.48 kWh. The controller operates in an operating voltage range of 350–435 V and can handle a maximum current of up to 30 A.
The BDU is unique in that it has IP65 protection, making it suitable for both outdoor and indoor installation. It is small in size (708 × 200 × 170 mm), lightweight (7.5 kg), and can be installed quickly thanks to its modular system.
Main features in brief:
- Battery controller for Sofar BTS 5K modules
- Number of manageable modules: 1–4 pcs (5.12–20.48 kWh)
- Operating voltage range: 350–435 V
- Maximum current: 30 A
- Communication: CAN interface
- IP65 protection → indoor and outdoor use
- Small size, easy installation (708 × 200 × 170 mm, 7.5 kg)
The special feature of the Sofar BTS 5K-BDU is that it is the essential central controller for BTS 5K modules, which simultaneously ensures safe operation, scalability, and integration with the 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.
