Boasting 23 years of experience in delivering solutions in the energy sector, LG Chem is recognised as an industry leader in lithium-ion batteries and offers a wide range of products to meet a broad range of application requirements.
LG Chem’s energy storage systems store surplus energy generated from rooftop solar panels for use at night or on poor weather days. Its RESU solar battery series consists of six products, which are compact, easy to install and suitable for both indoor and outdoor installation.
LG Chem RESU Solar Batteries
The RESU solar battery series by LG Chem offers product options ranging from 3.3kWh to 13.1kWh and includes 48V models available in 3.3kWh, 6.5kWh, 9.8kWh and 13kWh. The RESU series also consists of 400V batteries, available in 7.0kWh and 9.8kWh sizes.
LG Chem’s residential energy storage systems are compact and lightweight to allow for fast and easy installation indoors or outdoors, and you can connect all models of the 48V line-up with a RESU Plus box. RESU Plus is an expansion kit that allows you to combine up to two 48V RESU batteries. In addition, the RESU series is compatible with a range of inverters.
As the LG Chem RESU enables you to generate your own energy, it can help you be more energy independent. You can use the energy stored in your RESU battery to meet your energy needs when the sun has set, when energy demand is high or when you experience a power cut.
Below, you can find more information about the two product line-ups in the LG Chem RESU series.
