About LG Chem, Solar Batteries

LG Chem solar batteries review

LG Chem have been in the battery business for a very long time - so they know a thing or two about whacking together, err, carefully crafting battery systems. The company began mass production of Korea's first lithium-ion batteries way back in 1999 and by the end of 2011, it was the world's third-largest manufacturer.

While LG Chem somewhat lacks the glitz and glamour of Tesla, it's been a quiet achiever on the Australian home energy storage front and its solar batteries have been quite popular here.

Its flagship products are the LG Chem Resu range of solar battery systems, with current models ranging in capacity from 6.5kWh to 13kWh. It's important to note that whatever model you get, the capacity noted is nominal. Useable capacity will be lower - for example, the LG Chem Resu 13 has a nominal capacity of 13.1kWh and a useable capacity of 12.4kWh.

The power rating ranges from 4.2kW steady, 4.6kW peak (for 3 seconds) for the RESU 6.5 to 5kW steady, 7kW peak (3 seconds) for the RESU 13, so it has a fair bit of grunt.

For more specifications on various models, check out our battery storage comparison table.

LG Chem Resu Pros And Cons

Among the benefits of the LG Chem Resu batteries is it can be used in both off-grid and hybrid setups. It's also a compact battery thanks to the use of lithium nickel manganese cobalt oxide (NMC) technology, but NMC tends to have a shorter cycle life and degrades more rapidly than chemistries such as Lithium Iron Phosphate (LiFePO4). 

One of the drawbacks of the battery is it is warranted to 45ºC ambient temperature - but this is only problematic in some parts of Australia (although "some" is growing due to climate change impacts).

While on the topic of weather, these batteries are IP55 rated, so they can be installed outdoors as well as indoors.

LG Chem Resu Warranty

As with most good quality home energy storage systems these days, the LG Chem Resu has a 10 year warranty. While a manufacturer warranty is only good if the company is around to honour it, Australian Consumer Law comes into play - and the chances of LG going under aren't particularly high. They've been around a long time and there's nothing to indicate that won't continue.  

The company warrants its batteries will retain at least 60% of storage capacity for either 10 years after the date of the initial installation or for a minimum energy throughput that varies according to model - whichever comes first.

With a solid history in battery manufacturing and still a solid company today, LG Chem are worth considering if you have your heart set on acquiring a solar battery system.

If you're one of the many Australian LG Chem Resu owners, others considering a purchase would be curious about your experience - leave a rating and review.

12 months in and working well

Seems to deliver as expected. Sometimes thee is a strange low volume high-pitched buzz coming from the battery during discharge. I am advised that this is normal, but it seems odd.

I have two LG RESU10H batteries, one on each inverter. They are rated at 10kWh each with 9.3 kWh useable. The system protects the battery by not discharging below 20%. Generally the batteries charge up by around 11am and discharge after the sun goes down. They often last through till 10 or 11pm before we start using grid power. Data shows they are providing at least 17kWh per day (except on really cloudy days).

On days that are partly cloudy, they can fully charge, then discharge partially during the day and then recharge again. This means they can provide more energy for use - just yesterday battery energy used was 25 kWh due to this multiple charging in one day.

Resu 10 battery. during witer this does not quite get us through the night. Same in summer with aircon going. So considering another battery.

Quite disappointed in the lack of monitoring capability of the device, which is only through the inverters software. a imbedded adhoc WIFI or the ability to connect to your WIFI system to provide cell level monitoring etc. would be great. i also need to find the recommended battery discharge level recommended of the battery as the inverter is set to 20% discharge. But would like to confirm with the battery manufacturer if this is inbuilt in the BMS system in the battery hence the inverter setting of 20% would not apply as this would be taken into account within the LG battery itself.

LGchem RESU10LV

The unit was easy to install, although brackets to raise the unit off the ground need to be purchased separately. It is mounted inside a plant room and not exposed to eternal weather conditions. The installation manual is clear and precise. There is limited system information on the LG, other than On/Off, Charging, Discharging. It is paired with a Sunny Island 6.0H. Most of the battery information is via the Sunny Island such as Voltage, SOC % and charging/discharging rate (displayed as either + or - kilowatts) and the number of battery cycles that have occurred.

After installing a 9.8Kwh battery I had thought that it may have been a little bit too big. But being winter this has been able to handle most of our evening heating needs so far.

We decided to team our solar panels with a LG Chem Lithium Ion Battery 9.8kWh [400V]. One week after installation we had a blackout, so we could quickly see the benefit of having a battery - continuous power!

In my circumstance and because I have a whopping big air conditioner I get about 3 hours use at night. It also cuts in to essential appliances upon a power failure.

Altogether very happy with LG and especially with their response after contacting them regarding the failure. LG immediately initiated the warranty replacement

It is good that this is able to be installed in an outside shady location. Linked with the GoodWe inverter, we can see easily that we are making good use of the power from the battery once the panels cease directing power to house each day. It is covering our night use fully at the moment.. early Spring. We expect this to continue mostly like this until late Autumn.

In hindsight it looks like we need two batteries to be off the grid for most of the time. Currently our set-up means we are 70% self-sufficient, but the the offset we get from feed-in tariff should make our power bills next to zero.
