LG RESU Batteries: Unpacking Performance and Value

The LG RESU battery has carved a niche for itself in the ever-expanding residential solar energy storage market. Manufactured by LG Chem, a subsidiary of the South Korean conglomerate LG Corp, the LG RESU battery comes in a variety of sizes to fit various household energy requirements. 

This review will assess the LG RESU in terms of capacity, efficiency, aesthetics, ease of installation, and price to offer an overarching perspective of the product.

Capacity and Efficiency

One of the standout features of the LG RESU battery is the diversity of its product lineup. 

With capacities ranging from 3.3 kWh to 13 kWh, LG offers options tailored for modest, mid-sized, and expansive energy needs. This adaptability ensures that you can easily find a battery compatible with your household’s consumption patterns. 

The LG RESU batteries employ lithium-ion technology, ensuring high energy density and efficient discharge rates. The 95% depth-of-discharge (DoD) of the latest models is commendable, meaning you get more usable energy from your total capacity.



The LG RESU battery series maintains a sleek, minimalist aesthetic with its two-tone gray case. The design is compact enough to allow wall-mounted installation which helps save floor space in your home. 

The relatively small footprint, compared to other competing models, is a welcome feature for homeowners looking for a less obtrusive setup. It is also IP55 weather-resistant to allow for outdoor installation if desired.

Ease of Installation

One of the high points of the LG RESU battery is its ease of installation. 

The batteries come with straightforward instructions, making them accessible even for DIY enthusiasts with a basic understanding of electrical systems. 

However, it is advisable to get it professionally installed to make the most out of the warranty and ensure optimal functioning. Compatible with a wide array of inverters and solar panel systems, the LG RESU provides greater flexibility when integrating into existing setups.


As for the price, the LG RESU battery falls into the premium category. While initial costs are higher than some other options on the market, it’s essential to consider the longer-term benefits. 

LG Chem is known for its reliable technology and longevity, with a warranty period of up to 10 years on some models. This durability can offset the upfront costs when considering the lifetime value of the product.


The LG RESU battery offers an impressive combination of capacity, efficiency, and aesthetic appeal. Its diverse product range makes it a viable choice for various household sizes and energy needs. 

The high DoD and compatibility with multiple inverters make it a flexible, efficient storage solution. Although it comes with a premium price tag, the long-term benefits and reliability make it a worthy investment. 

For homeowners looking for a high-performance, long-lasting, and aesthetically pleasing energy storage solution, the LG RESU battery stands as a solid choice.
