Product description
Product description
BYD Battery-Box Premium HVS is a high-voltage, modular energy storage system developed for residential and small commercial solar PV systems. The system uses BYD's proprietary cobalt-free lithium iron phosphate (LFP) cells, which provide superior safety and long cycle life.
Available versions:
- BYD Battery-Box Premium HVS 5.1 – 5.12 kWh
- BYD Battery-Box Premium HVS 7.7 – 7.68 kWh
- BYD Battery-Box Premium HVS 10.2 – 10.24 kWh
- BYD Battery-Box Premium HVS 12.8 – 12.80 kWh
Each HVS system consists of 2-5 modules, which are connected in series to form a high-voltage architecture. The modules are connected to each other using an internal, cable-free plug-in system, which simplifies installation and minimizes the possibility of errors. The entire system can be expanded up to 38.4 kWh capacity by connecting three identical units in parallel.
One of the main advantages of the HVS series is the true high voltage (HV) series connection, which results in high energy transfer efficiency (≥96%). The built-in BMS continuously monitors the status of all cells – voltage, temperature, current – and performs automatic cell balancing.
BYD's patented modular design allows for future expansion without having to replace the entire system. The IP55 housing is suitable for both indoor and outdoor installation, and the operating range from -10°C to +50°C ensures stable performance.
- Available capacities: 5.1 / 7.7 / 10.2 / 12.8 kWh
- High voltage (HV) architecture that can be built from 2–5 modules

- IP55 protection, for indoor and outdoor installation
- Compatible with leading inverter manufacturers (e.g. Fronius, GoodWe, SMA, Sungrow)
- 6000+ charge cycles, 10 year warranty
- Certificates: VDE 2510-50, IEC62619, CE, UN38.3
The BYD Battery-Box Premium HVS series is a reliable, high-voltage solution that offers high efficiency, modular expandability and exceptional safety. It is the ideal choice for both self-consumption enhancement and stand-alone or backup power applications.

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.
