LG Chem Lithium-Ion Batteries: For Solar Energy Needs Of Homes And Commercial Premises

The efficiency and reliability of your solar power system are determined by the solar panels, battery storage system, and inverters it contains. An efficient battery storage system is vital for ensuring your home receives an uninterrupted power supply at all times. It can also help you save more on the electricity bill by providing a reliable source of energy thereby allowing you to go off-grid.

LG Chem is one of the largest manufacturers of lithium-ion batteries in the world. Let’s take a closer look at what LG Chem batteries can offer to your solar power system to help it work more efficiently and reliably.

Why LG Chem

When it comes to solar power energy, LG Chem has earned a reputation for producing the most efficient, reliable, and cost-effective power supply to residential premises and industries. It is one of the largest manufacturers of lithium-ion batteries in the world.

The company supplies a wide array of energy storage products for homes as well as large scale industries including portable electronics (mobile phones), electric vehicles, and stationary applications.

Let us have a look at the specifications of LG Chem solar batteries and how the excellent performance of these batteries could help you save more on electricity bills.

Technical specifications of LG Chem battery storage system

As revealed earlier, LG Chem offers a wide range of solar batteries. The RESU (Residential Energy Storage Unit) range from this repeated brand consists of 48-volt as well as 400-volt battery options making it suitable for most households and even commercial premises having a varying power consumption.

The 48V series of low voltage batteries is available in different sizes of 3.3kWh, 6.5kWh, 9.8kWh, and 12.4kWh with a usable capacity limited to nearly 90%.

Larger residential complexes or multi-family households with higher power requirements can choose larger batteries with a maximum of 19.6kWh by combining two units of RESU10 (9.8kWh) batteries using a battery combiner device, RESU Plus.

The 400V series of high voltage batteries are available in 2 sizes – 6.5kWh and 9.8kWh – thus catering to the needs of small scale and large scale industries. The hight voltage batteries have a usable storage capacity of nearly 95%. The high voltage batteries also offer additional benefits in terms of lower cable losses and increased efficiency. 

Solar experts at Sunface Solar recommend LG Chem RESU batteries for those residing in locations with unpredictable or harsh weather, especially very hot summers.

These batteries are IP55 weather-rated, which means you can install them even in a semi-outdoor location like your carport or verandah, when placing the battery system at a place exposed to direct sunlight is not recommended due to the risk of damage by harsh sunrays.

The lithium solar energy storage batteries by LG Chem are compatible with most off-grid and hybrid battery inverters and chargers available in the market. They can be easily configured with any inverter making them suitable for even those having an existing solar power system.

Unlike most other manufacturers that use cylindrical cells for the solar energy back-up system, LG Chem uses an innovative Polymer ‘pouch’ flat and laminated battery design that could enable higher energy density, increased reliability, and safety.

Also, layering these battery cell sections instead of bending or rolling them reduces the chances of failure and supports heat dissipation over the cell area in an even manner. This can also improve the durability of your battery system.

RESU GEN2 48V and 400V

  • These batteries are suitable for small households as well as large industries. You can choose 48V or 400V battery systems depending on the specific energy needs of your house or commercial premises.
  • The batteries can store extra energy produced by solar panels to be used at a later time. These batteries allow you to power up your home at all times including when the cost of electricity is high and during a power outage.
  • The RESU batteries provide a reliable power supply to your home with its efficient energy storage system and industry-leading durability.
  • The sleek and compact design of these RESU batteries support easy installation. You can place them indoors as well as outdoors.
  • Sunface Solar trusts LG Chem’s lithium-ion batteries for the safety they offer. These batteries have a proven safety record even in the ESS and automotive industries.
  • Up to 2 units of the RESU battery back-up systems can be combined together to increase the energy storage capacity of your solar power system.
  • With these batteries installed in your solar energy system, you would be good to go independent from your power grid.
  • On the service side, LG Chem ensures your RESU battery system is installed correctly, thanks to the intense training and support it offers.


The superior performance of the stationary battery systems has allowed LG Chem to position itself as one of the leading manufacturers of commercial and home solar energy storage systems.



LG chem RESU offers one of the best battery back-up systems with a remarkable reputation for reliability, affordability, and quality. LG Chem batteries provide several benefits including cost efficiency, higher safety, and better performance along with unique cell design, and compatibility with most inverters.

Sunface Solar recommends LG Chem for the efficient energy storage system for your solar power system. These batteries stand out among the crowd of lithium batteries available in the market due to their diverse range, high build quality, and value for money.
