Our LG Battery Review. Are LG Chem batteries any good?

Yes. They are a Korean company, part of LG group, who are one of the largest companies in the world. 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.

The LG Battery Buying Guide is:

This is not an ‘All In One’ Energy Storage System. You will need a compatible Hybrid Inverter.

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

Review your household Energy Throughput over 10 years do and make sure it is within the Perfomance 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.

Our detailed LG Battery Review

What is the Return of Investment of a LG Battery?

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 the 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. Here in Australia we get very cold temperatures in Winter and very hot temperatures in Summer. Even so it is usually recommended that solar batteries are keep away from direct sun. LG Chem batteries have a wide range of operating temperatures.

Are LG Battery’s 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 a LG Battery cost?

LG Chem RESU 6.5 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. Not sure what Battery is best for you? Our local Solar Run Franchise can do a details LG Battery Review for you.

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. So the LG Chem is a battery system and you can simply add more as long as your Inverter allows it.

What is the LG Chem Battery Warranty?

LG Chem Battery’s come with a 10 year product warranty. 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 that I found at the time of writing this review. LG Chem Battery Warranty PDF. Please note, Warranty’s 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.
