LG Chem Resu

LG Chem resu solar battery storage range

Solar Battery Storage Solution

With 22 years of experience in successfully delivering products and solutions to customers in the global energy sector, LG Chem Resu is recognised as the industry leader in Lithium-ion battery manufacturing.


LG Solar Battery offers a wide variety of products, such as Battery Cells, Modules, Packs, Racks, and Containers that allow their customers to source total solutions.


An ESS can store surplus energy generated from rooftop photovoltaic panels for use when needed. When the sun has set, energy demand is high, or there is a black-out, you can use the energy stored in your ESS to meet your energy needs at no extra cost. In addition, an ESS helps you pursue the goal of energy self-consumption and ultimately energy-independence. LG Chem Resu make effective backup batteries for solar power.

Key Features of New RESU Series

Compact Size & Easy Installation: The compact and lightweight nature of the RESU is world-class. It is designed to allow easy wall-mounted or floor-standing installation for both indoor and outdoor applications. The inverter connections have also been simplified, reducing installation time and costs.

Powerful Performance: The new RESU series features industry-leading continuous power (4.2kW for RESU6.5) and DC round-trip efficiency (95%). LG Chem’s L&S (Lamination & Stacking) technology provides durability ensuring 80% of capacity retention after 10 years.

Proven Safety: LG Chem places the highest priority on safety and utilizes the same technology for its ESS products that has a proven safety record in its automotive battery. All products are fully certified in relevant global standards.

Diversity in Product & Capacity Options: A total of five different models are available to meet customers varying needs with respect to voltage and

capacity. With the RESU Plus, all 48V models can be “cross-connected” with one other 48V unit of any capacity. This allows the RESU range to offer energy storage capacities from 3.3kWh to 19.6 kWh.

LG Chem Resu - LG Solar Battery

The LG Chem is a DC coupled battery solution. This means it needs to be combined with an inverter to charge and discharge the battery. 


Egensys consider the best combination is to pair the battery with a Hybrid inverter system such as the Solax X-Hybrid or SolarEdge StorEdge. These units simultaneously operate as a Solar PV inverter as well as a battery inverter.
