Product description
Product description
The Sofar BTS DS5 series is a smart, modular energy storage system developed for residential and small business solar systems. It is designed for easy installation, flexible expansion, and efficient operation with a long service life.
Available versions:
- Sofar BTS E5-DS5 – 5.12 kWh
- Sofar BTS E10-DS5 – 10.24 kWh
- Sofar BTS E15-DS5 – 15.36 kWh
- Sofar BTS E20-DS5 – 20.48 kWh
The BTS DS5 series is made up of 5.12 kWh modules, which can be connected in series to increase the total capacity. The largest model, E20, contains four modules, with a total of 20.48 kWh of nominal and 18.9 kWh of usable energy storage. An integrated distribution unit (BTS E5-BDU) ensures voltage distribution and system monitoring, while CAN communication allows for precise data exchange with the inverter.
The system is based on lithium iron phosphate (LFP) cells, which are cobalt-free and have a long lifespan. The built-in battery management system (BMS) continuously monitors the temperature, voltage and current of the cells, automatically balancing charging and discharging. A low-power sleep mode and one-button start simplify operation.
The BTS DS5 sets have a modular housing that can be vertically expanded and installed as wall or floor mount. The IP65 protection rating is suitable for both outdoor and indoor use, while the operating temperature range of -10°C to +50°C ensures stable performance all year round.
- Available capacities: 5.12 / 10.24 / 15.36 / 20.48 kWh
- Modular, stackable design (1–4 modules)
- LFP cell technology, cobalt-free, safe operation
- Integrated BDU unit for power sharing and control

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.
