LG Chem RESU Batteries for Superior Off Grid Energy

LG Chem RESU (Residential Energy Storage Unit) Batteries are one of the biggest successes in off-grid home energy storage in Australia. The compact nature of the RESU is world-class, and it is designed to allow easy wall-mounted or floor-standing installation for both indoor and outdoor off grid applications.

The Enclosure Protection Rating of the RESUs is IP55 which means they’re protected against both dust and water. Like most new battery storage systems apart from keeping them clean LG Chem RESU batteries will require no ongoing maintenance. LG Chem rates round-trip efficiency of the 48Volt RESUs as 95%, and they can be installed outdoors exposed to temperatures above 30 degrees or below 15 degrees. RESUs can function at ambient temperatures from -10 to 45 degrees Celsius making them perfect for Australia’s harsher environmental conditions.


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.

LG RESU Lithium-Ion Battery Systems are Revolutionizing Off Grid Energy in Australia

Using LG RESU batteries for off-grid energy allows for a broad range of installation options, perfect for those limited in space, RESU batteries have an advanced design that is more compact and powerful than other systems currently available on the Australian market.

LG RESU Lithium Ion Batteries are warranted to retain at least 80% of their nominal capacity for 10 years or until they have stored slightly under 2,500 kilowatt-hours for each kilowatt-hour of nominal capacity. LG Batteries are built with internal componentry that uses an innovative design that they call lamination and stacking. This eliminates dead space and minimises distortion, contributing to energy density and battery life.

LG Chem RESU’s cutting-edge technology provides durability ensuring unlimited cycles per day.


SMA & LG RESU Lithium-Ion Battery Systems for Superior Off Grid Energy

LG RESUs are high power battery systems.  For off-grid applications, higher power allows more appliances to be operated at once without tripping the system.  LG RESUs are the most compact and energy dense battery systems currently available.

Your off-grid system works by teaming an LG RESU Battery with an SMA – Sunny Boy + SMA Sunny Island Inverter.


The major benefit of this off-grid system is that your battery storage and inverter are separate so should any componentry ever fail or become damaged you will not have to remove your entire off grid battery system. This is a preferred option for many off-grid customers.

The combination of SMA and LG RESU’s means that you’re getting the best battery and inversion technology available. SMA are a leading manufacturer of solar inverters.

An Off Grid Solar Solution that is Modular & Expandable to Cover Future Energy Needs

An LG RESU Off Grid Solar System allows you to benefit from a smart modular design. This lets you start with what you need now, and have the confidence that adding additional components down the track will be intuitive and easy. With products designed to function seamlessly together, and a stackable battery system our off-grid systems work in the now and into the future. Have peace of mind in your ability to upgrade should you require more energy if your circumstances change.

The best Off-Grid Solar Lithium Ion Battery Systems – SMA and LG RESU a winning combination changing the landscape of Off Grid Solar in Australia.

LG Chem RESUs have become one of the most popular choices for Off Grid energy storage because of their compact size, maintenance-free operation, and exceptional 10 Year Warranties. When you combine these superior batteries with SMA the best German designed solar inverters on the market which are known for their quality, level of service and exceptional monitoring capabilities, you get an outstanding off grid solution that will take you into the future and beyond.
