Product description
Product description
The BYD Battery-Box Premium HVS and HVM modular battery series are designed for residential and small industrial energy storage systems. The modules do not work on their own, in all cases the BCU+BASE control unit is required, which ensures battery monitoring, protection and communication with the inverters.
Two types of battery modules are available:
- HVS module (2.56 kWh) – composed of 2–5 modules 5.1–12.8 kWh capacity, 3 towers in parallel → max. 38.4 kWh
- HVM module (2.76 kWh) – composed of 3–8 modules 8.3–22.1 kWh capacity, 3 towers in parallel → max. 66.2 kWh
The system can thus be scaled from 5.1 kWh to 66.2 kWh, making it flexible to serve the energy needs of single-family homes and larger facilities.
The Premium series features patented plug-in connection technology, which allows modules to be connected without internal cabling. This means faster installation, less chance of errors and safer operation.
Lithium iron phosphate (LFP) cells are cobalt-free, fire-safe and offer a long lifespan (≥6000 cycles). The system is also suitable for high-power backup and off-grid operation thanks to the high-voltage series connection.
Main features in brief:
- Central controller: BYD BCU+BASE module is mandatory for all systems
- Solid LFP technology, cobalt-free cells
- Patented plug-in connection, no internal wiring
- Round-trip efficiency: ≥96%
- Compatible with 1- and 3-phase high voltage inverters from leading manufacturers
- IP55 protection, suitable for indoor and outdoor installation
- Functions: self-consumption maximization, backup, off-grid, tariff optimization
- Safety certificates: VDE 2510-50, IEC62619, UN38.3, CE
The BYD Battery-Box Premium HVS and HVM combine modular expandability, high efficiency and the highest level of safety in one system. Together with the BCU+BASE controller, they provide a flexible, long-term scalable energy storage solution for both single-family homes and larger projects.

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.
