Huawei’s flagship ESS

BEYOND MODULAR DESIGN

A comprehensive analysis of Huawei’s residential LUNA2000 Smart String Energy Storage System

With a growing number of homeowners joining the solar trend and turning their houses into power plants, the home energy storage system (ESS) – a device that stores electricity as chemical energy – plays a vital role in the unprecedented energy transition.

Not only does an ESS increase the selfconsumption rate of solar energy but it can also provide critical support during power outages or load shedding. A home energy storage system, equipped with backup power boxes, can keep our internet and household appliances running. From Australia to Italy, from Vietnam to the Netherlands, Huawei’s smart string energy storage system LUNA2000 lights up homes with clean energy around the world.

LUNA2000, the flagship product of Huawei FusionSolar Residential Smart PV Solution, is a residential energy storage system (ESS) launched in 2021.

Four reasons to choose LUNA2000 One-fits-all solution to streamline installation and maintenance processes

With the energy optimiser, LUNA leverages tried-and-trusted technologies to ensure system-level active safety, easier management and scalable modular layout. This all sounds great but when in practice, what does it do to help professional installers and tech-savvy homeowners alike?

Eye-catching, award-winning design

LUNA2000 is a plug-and-play home battery system without pre-charging. Once LUNA2000 has been turned on, all components of the system are automatically recognised and configured by the FusionSolar App.

Everything you need to know about the system performance will be displayed on the App whose commissioning takes just five minutes. With the App, O&M staff can easily identify which PV module or battery module underperforms, realising the module-level fault detection and improving efficiency.

Gone are the days of clumsy and piecemeal home storage systems with Huawei’s OneFits-All Residential PV Solution, which includes the inverter, the optimiser, the ESS and the App.

All components are designed and manufactured by one company, so you don’t need to deal with different component suppliers, streamlining the maintenance process.

Three layers of safety protection to keep you safe

LUNA2000 has recently been awarded iF Design Award 2021, one of the world’s three most prestigious design awards, also known as the ‘Design Oscar’. The compact, smooth, sleek, and waterfallinspired aesthetic design of LUNA2000 is a fabulous addition for homeowners.

Easy and flexible configuration

With the innovative modular design, one single storage system is composed of up to three 5kWh battery units that can be stacked on one another to offer 5, 10, and 15kWh storage options to meet customers’ different needs. It allows for another same system to be joined in parallel, sitting side by side, to scale the total capacity of the battery system to up to 30KWh.

With the power modular on top, the high voltage battery is compatible with both single and three phase residential inverters from Huawei.

Maintaining personal and property safety should be a priority when investing in any solar power system. In recent years, a growing number of branded home batteries have been recalled over fire concerns. Some energy storage systems fail to provide enough protection from overcharge, over-discharge and internal short circuit conditions, which can cause fire and explosion hazards.

By treating customers’ safety as the number one priority, Huawei has added three layers of protection to achieve active safety, including AI-powered internal cell short circuit diagnosis to avoid fire hazards, cell-level temperature control to detect overheating and optimiser-enabled 0V rapid shutdown for safer installation and maintenance.

The AI-powered internal cell short circuit diagnosis can precisely analyse the charge/ discharge voltage curve of each cell, preventing false alarms and missing alarms. A sudden drop in cell voltage will trigger the immediate isolation of the faulty battery module to fend off dangers.

Each battery module of the LUNA2000 home battery has eight sensors to supervise the operating status, enabling temperature control at the cell level. Each sensor works independently and monitors two cells, achieving higher monitoring precision. Each module also has a unique fire extinguishing bag to offer maximum safety.

Besides, LUNA2000 adopts the lithium iron phosphate solution that is the most chemically stable and cannot self-ignite. www.huawei.com
