Product description
Product description
The Huawei LUNA2000-S1 series is the manufacturer's new generation, higher-performance energy storage system. The devices are designed for home and small commercial solar systems where energy storage flexibility, safety, and quiet operation are important.
Available versions:
- Huawei LUNA2000 – 7 kWh
- Huawei LUNA2000 – 14 kWh
- Huawei LUNA2000 – 21 kWh
The system is based on 6.9 kWh battery modules and can be modularly expanded up to 20.7 kWh within a single unit or up to 82.8 kWh by connecting multiple systems. The design is simple: a Power Module controls the battery units, which are connected to each other without the use of cables.
The LUNA2000-S1 series uses a “Module+” architecture with a built-in power optimizer. This ensures that each module operates independently and efficiently, ensuring that the overall system performance is always balanced. The battery allows for a 100% depth of discharge (DoD), allowing the full energy storage capacity to be utilized.
The 5-layer safety protection operates at multiple levels (cell-level, electrical, structural, active and emergency protection). The LFP cell technology ensures stable operation and long service life, while the system noise level remains below 29 dB. Cooling is by natural convection and requires no maintenance.
The operating range from -20°C to +55°C, IP66 protection, and outdoor and indoor installation allow for versatile use. Installation is made easy with cable-free connection and automatic setup via the FusionSolar app.
- Available capacities: 7 / 14 / 21 kWh
- Modular expandability up to 82.8 kWh
- 100% depth of discharge (DoD)
- Per built-in energy optimization module
- 5 levels of security protection (from cell to system)
- Cable-free connection, quick installation
- Natural cooling, noise level <29 dB
- Operating range from -20 °C to +55 °C
- Compatible with Huawei SUN2000 inverters
- IP66 protection, for outdoor and indoor installation
The Huawei LUNA2000-S1 series is an improved version of previous models. It is an easy-to-install, safe and durable energy storage solution that adapts to changing consumption needs and the expectations of modern solar systems.

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.
