LG Battery Review | Are LG Chem batteries any good?

Yes. Our review of the LG Battery found that its price and performance make it an accessible and powerful home energy solution. The RESU, or ‘Residential Energy Storage Unit’ range has diverse options; the 6.5, 6.5+VPP and the 10. Each of the LG Chem RESU options are highly competitive when considering the quality of the product and the return on investment.

Investing in Battery Storage systems are expensive. With this in mind, this LG Chem Battery review recommends LG when both price, performance, and a known brand are the most important considerations. The main residential versions are available in  6.5kWh, 9.8kWh and 12.4kWh options. For Vic & SA residents, before you buy, check out the Solar Victoria and South Australian Home Battery Scheme Rebates.

LG Chem batteries have been widely installed in Australia being well suited to Australian conditions. Almost all LG Chem Reviews agree that these are one of the best battery options in Australia. LG Chem Australia is based in Melbourne, VIC. This battery is widely compatible with major solar inverters and can be set up to be VPP ready. If you are looking for a high performing battery then you will be looking at an LG Chem battery.

Extras not included

This is not an ‘All In One’ Energy Storage System. Other products like the Tesla and the Sommen batteries are all-inclusive. With the LG solar battery however, you will need a compatible Hybrid Inverter.

Location, location, location

You will need to be careful where the LG Chem Battery is mounted. Warranty will be void if the temperature falls below -10 degrees or goes above 45 degrees while it is operating. In your garage is typically the best location.

Check yourself

Review your household Energy Throughput over 10 years and make sure it is within the Performance Warranty for Energy Throughput. How many cycles per day impacts your Energy Throughput.

Review your household consumption and the time of day you use your electricity. A good Solar Retailer like Solar Run can help you match the solar system size with your Battery Requirements.

What is the Return of Investment of a LG Battery?

This is one of the most important questions to answer when considering whether to invest in a solar battery. For many Australians, you will find that the initial costs of purchasing and installing a solar battery are quickly paid back by the savings you will make on your energy bill. For maximum efficiency and compatibility, you can buy both LG Solar Panels and LG Chem Battery Systems. LG have a very detailed Return on Investment calculator on their website. You will need to consider your usage patterns (day or evening user), cycles per day, electricity rate and the overall cost of the installation.

Are they suitable for Australian Conditions?

Yes. All of their batteries are clean energy council approved. This means it has passed all the test for Australian Standards. Widely sold in Australia, LG Chem provides market leading batteries. It will be a surprise to no one that the climate in Australia can be extreme. We get very cold temperatures in Winter and very hot temperatures in Summer. With some products, this extreme change and gruelling conditions can deteriorate the components and impede the performance. As such, it is usually recommended that solar batteries are kept away from direct sun. LG Chem batteries have a wide range of operating temperatures.

Are LG Batteries compatible with ALL Inverters?

No. You will need install a Hybrid Inverter that is CEC approved and is compatible with the LG Chem Battery. Some batteries are only compatible with a very limited range of Inverters while others are compatible with many different Inverters. LG Chem batteries are compatible with many different Inverters including SMA, Fronius, GoodWe, SolaX and Growatt.

How much does the LG Chem Battery cost?

The LG Chem RESU 6.5 price will roughly cost you between $8,000 to $10,000 installed. This includes a hybrid Inverter. If you are in either South Australia or Victoria, you can get a really value. For the same money (or less) you can get a LG Chem RESU 10. Up to 50% of the purchase price of the installation will be given back to you buy either Solar Victoria or the South Australian Home Battery Scheme. In Victoria, it goes 1 step further. You can also get a 0% interest loan over 5 years. Not in those states? Well unfortunately your paying full price.

Are they VPP (Virtual Power Plant) ready?

Yes. LG Chem batteries are a great choice if you are considering signing up to a VPP (Virtual Power Plant). A VPP, for those not familiar with the term, allows many solar systems to act together as a power plant. Collectively a VPP can then store power when it is cheap and sell it when the price is higher more effectively than a single solar system owner. VPPs are not yet common but being “VPP ready” is a must to claim the South Australian Battery Scheme.

Is it an expandable Battery System?

Yes. It is one advantage of not having an ALL IN ONE battery storage system like a Sonnen or Tesla. As opposed to a single unit with everything you need, the LG Chem battery is expandable. So the LG Chem is a battery system that you can simply add more to, as long as your Inverter allows it. This provides the opportunity to upgrade and enhance as new technology and products are released.

What is the LG Chem Battery Warranty?

LG Chem Batteries come with a 10 year product warranty. This is a crucial benefit for those concerned about the the LG Battery’s price. As such, the Performance Warranty is worth reviewing in detail. There are 2 parts to this warranty and it whatever comes first:

  1. 60% of Nominal Energy for 10 years after the date of installation or;
  2. Energy Throughput of less than 10mWh for LG Chem RESU 3.3, 20mWh for LG Chem RESU 6.5 or 30mWh for LG Chem RESU 10

Here is the latest LG Chem Battery Warranty at the time of writing this review. LG Chem Battery Warranty PDF. Please note, Warranties are often updated, so at the time of getting a quote, ask your Solar Retailer to give you the most recent Warranty Card. No doubt, there will be significant improvements each year with Energy Storage Systems, so stay in touch.

The Verdict

The LG RESU range offer quality products with an affordable price tag compared to its competitors. In addition to the LG Chem Battery price, its compatibility with major solar inverters make it a versatile and adaptable battery. This is important as the RESU range are not considered an ‘all in one’ Energy Storage System – as you will need a Hybrid Inverter that is compatible.

While the 10 year warranty provides security to your investment, customers must be cautious of the placement of their battery as issues with temperature can void the warranty. Nonetheless this extended performance warranty will alleviate the financial concerns of many customers.

Our review of the LG Chem Battery finds common ground with Australian consumers who have rated it as one of the best solar batteries on the market. If price and performance are the main criteria for you, then the LG Chem Battery could be the ideal choice. However, if you would prefer an all-inclusive system then there are many other options more suited to your needs.

Do your homework. Check out other products on the market and asses your options.
