Product description

The Sofar BTS 5K is a 5.12 kWh high voltage (400 V DC) lithium iron phosphate (LFP) battery module designed specifically for Sofar energy storage systems. It cannot be used stand-alone, it always requires the BTS 5K-BDU control unit, which provides module monitoring and communication with the inverter.

The modular design allows 1-4 BTS 5K modules to be connected to a BDU, allowing the total system capacity to be expanded from 5.12 kWh to 20.48 kWh. This provides flexibility for single-family homes, small commercial buildings, or systems requiring backup power.

The BTS 5K features extremely low self-consumption in sleep mode and user-friendly one-button operation that simplifies everyday use. The IP65 protection design allows for both indoor and outdoor installation, and natural cooling ensures noise-free operation.

Main features in brief:

Capacity: 5.12 kWh per module
Rated voltage: 400 V DC
Cell technology: LFP (lithium iron phosphate)
Modularly expandable: 1–4 modules → 5.12–20.48 kWh
Compatible with BTS 5K-BDU controller
Extremely low self-consumption in sleep mode

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?

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?

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?

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?

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.
