LG Chem, Ltd. One of their main business units is Energy Solutions which extends its chemical expertise into high-tech areas such as rechargeable batteries. Throughout multiple production facilities and an extensive distribution network, LG Chem is a leading global company. 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.

LG have a very detailed Return on Investment calculator on their website.LG is a leader in the home electronics industry and manufactures some of the most popular panels featured in quotes to shoppers on the EnergySage Solar Marketplace. The LG Chem RESU pairs well with solar panel systems, especially if your utility has reduced or removed net metering, time-of-use ratesor demand charges. Installing a storage solution like the LG Chem RESU with a solar energy system allows you to maintain a sustained power supply during the day or night, as long as you store enough power from your panels when the sun is shining.

As with many other home battery products, the LG Chem RESU is sized for day-to-day use at your home and is often paired with a home solar panel system. When your solar panels produce more electricity than you can use in your home, you can store the excess electricity in the battery system instead of sending it back into the grid. As a dedicated chemicals company, LG Chem has the history and knowledge to back up their claims of quality and safety for their battery products.

And as one of the most popular residential batteries on the market, it seems that consumers agree. When evaluating the RESU, there are various important metrics and technical specifications to keep in mind.

Among the most important are the size of the battery power and capacityits chemistrydepth of dischargeand roundtrip efficiency. Two important metrics to keep in mind when comparing the RESU 10H to other home storage options are power and usable capacity. Power measured in kilowatts, or kW determines the maximum amount of electricity that can be output at a single time, while usable capacity measured in kilowatt-hours, or kWh is a measure of the maximum amount of electricity from your battery on a full charge.

The RESU system is also, to an extent, modular, meaning you can add multiple battery products to your storage setup. For example, you might want to install multiple RESU batteries for a home with high energy demands. Think of your battery like water running through a pipe. Energy capacity is the amount of water available to push through the pipe, while power is the size of the pipe itself. Larger pipes allow more water to flow through at once, which depletes the water faster.

Similarly, a battery with a high power rating can deliver more electricity at one time, but will burn through its available energy capacity faster too. Batteries with a higher power rating are capable of powering more robust appliances or many appliances at once, while batteries with a higher usable capacity can store more total energy and thus can run your appliances for longer periods of time without needing to recharge. The functionality of one solar battery next to another can vary; some batteries have excellent off-grid capabilities, while others offer software solutions for rate arbitrage.

LG Chem has made a concerted effort to ensure their battery solution is compatible with most common brands and types of off-grid and hybrid inverters. This means that, as long as your installer installs the correct components, your LG Chem battery will be able to provide backup power for your home when the grid goes down. This is one of the most common lithium-ion battery technologies, and for good reason: relative to other types of batteries, LFP batteries are known for their high energy density the amount of energy they can store relative to the physical space they take up and increased safety.

To learn more about how different lithium-ion battery chemistries stack up against one another, check out our overview of battery chemistry differences. Two key ways to evaluate the performance of a solar battery are its depth of discharge and roundtrip efficiency.

Because the useful life of a battery decreases each time you charge, discharge, and re-charge it, many battery manufacturers specify a maximum DoD level for optimal battery performance.

In general, batteries with a higher depth of discharge are considered better quality products. Roundtrip efficiency is a measure of electrical losses involved with charging and discharging a battery.

The higher the efficiency percentage, the more efficiently the battery is able to convert incoming electricity into stored electricity and then back into usable electricity. In most cases, homes with an RESU battery will charge and drain the battery every day. The RESU comes with a year warranty.You can edit the text in this area, and change where the contact form on the right submits to, by entering edit mode using the modes on the bottom right.

PV-TV E19: LG SOLAR BATTERY - What makes them great?

Melbourne, VIC, Australia. Detailed reviews and information of the best solar panels, inverters and batteries. Plus hybrid and off-grid solar system reviews and information articles on how solar and battery systems work. Plus hybrid inverters, battery sizing, Lithium-ion and lead-acid batteries, off-grid and on-grid power systems.

The large range of stationary lithium battery systems from LG Chem has positioned the company as one of the industry leaders in home solar battery systems and larger commercial energy storage ESS installations.

The 48V LV series is available in 3. For larger systems, a maximum capacity of The higher voltage HV V units are available two sizes - 6. This means they can be installed in a semi-outdoor location such as a verandah or carport, but should not be located in a position exposed to direct sunlight, especially during the warmer months.

Download the detailed LG chem specification data sheet here. However all dedicated off-grid battery inverters operate within the traditional 48V range so the higher voltage batteries will generally not work for off-grid installations.

There is a growing number of compatible high voltage hybrid inverters including the well regarded SolarEdge StorEdge hybrid inverter, the new Huawei FusionHome and the SMA sunny boy storage which is now available in higher capacity up to 6.

Unlike the first Tesla Powerwall which was limited to two inverter types the range of compatible inverter brands for the RESU range LV now includes a huge range 48V hybrid and off-grid inverters.

Warranty & Support

SolaX Power hybrid. Ingeteam hybrid. Sungrow SH5K hybrid. Goodwe SE. Victron Energy. SMA Sunny Island. SolarEdge Storedge. Huawei SUNL. Fronius Symo. More options coming - LG chem are also working closely with several leading inverter manufacturers including SMA, Fronius and SolarEdge and will be delivering an even greater range of battery options throughout As opposed to many other manufacturers which use cyclindrical battery cells LG chem use a unique Polymer 'pouch' flat laminated battery design PH3 which LG claim enables much higher energy density with increased reliability and safety.

Layering the battery cell sections rather than rolling or bending the cell structure reduces the likely hood of failure and enables even heat dissipation across the cell area. Fire Safe - The LG chem lithium modules have been fire tested to the UL test standard which requires there to be no explosion or sign of fire when the battery cells is forced into a thermal runaway condition.

The LG chem RESU warranty is 10 years which is based on 2 main factors, the remaining capacity and energy throughput based on charge and discharge cycles. The warranty states that See the full LG chem warranty document here. The warranty also contains detailed operating criteria which limits the operating temperature and energy throughput over the battery life.

This can be problematic for installations in hotter climates such as regional Australian towns and remote locations. See the complete solar battery comparison and review here for full details and specifications including estimated lifetime, cost per KWh, power output and compatibility with leading inverters. LG chem RESU is definitely one of the best battery systems on the market, with a extremely good reputation for quality and affordability. The only concern is in regards to systems installed in high temperature environments or exposed locations.

Prolonged high temperatures above 40 degC or direct sunlight could result in reduced performance or even system shutdown to prevent overheating. Another issue is the battery will automatically shut down after a short amount of time if communication is lost with the inverter.

However, this is really only problematic with off-grid systems. LG Chem really stands out from the crowd of lithium battery manufacturers due to high build quality, value for money, diverse range of batteries, and compatibility with most leading inverters on the market.Solar battery storage is the future of electricity and my business.

I had to get one to run it through its paces in the office. So which solar inverter did I install to charge the LG battery? The choice was made fairly simple. Solax X Hybrid. What strikes me about Solax it seems no-one in Australia knows how to pronounce their name yet. Apparently the Chinese company has been around for over ten years, but they have only gained a significance presence in Australia since the release of their Hybrid inverter.

To balance this cynicism, my technically minded friends at Supply Partners run their LG Chem with a Solax Hybrid and are suitably impressed with its capability of continuing to run when grid power is down.

For me, however, there was an obvious choice. MC Electrical have developed a solid working relationship with Sungrow over the last four years, and I have developed trust in them as a quality, reputable and cost-competitive manufacturer.

MC Electrical are the warranty agent for Sungrow in the south-east, so it was only natural that we learnt about their new Hybrid inverter. It has 6. If it cycles times a year, it is warranted for 10 years with a degraded nominal output of 60 percent in its 10th year.

In the middle hours of the day, if solar output decreases or our consumption peaks, the battery then kicks in and helps out.

It gets recharged later on during the day when we produce excess power. By about 4 pm, the solar starts to die off and the battery kicks in to help us finish our day. By the time we leave at 5. Expansion battery packs are available so we could double the size if needed. If you are looking to get a return on your investment, you may have to have a loose interpretation of the term. So what constitutes return? I break it down into three categories:. The financial return.

The LG warranty will allow you to use kWh in a ten year period.This page is for personal, non-commercial use. The so-called default judgment by the U. SK Innovation currently makes batteries for the Kia Niro electric crossoverswhich are made in Korea and exported to the United States. Automakers are scrambling to lock in supplies of batteries, which are the most expensive and critical part of EVs, to meet increasingly stringent emissions rules and rising consumer demand.

English Choose a language for shopping.Is the RESU battery a good option for your energy storage and how does it compare to the Tesla Powerwall — the most well-known storage option on the residential market?

They make appliances and other electronics like phones and televisions. Their LG Chem branch is one of the biggest battery manufacturers in the world, selling their lithium-ion batteries to more auto manufacturers than any other company.

By mid, LG Chem had officially entered the US with a few different options for energy storage, including batteries up to 9. The RESU battery is simply that: a box of batteries and nothing else. The batteries are designed for residential energy storage and are available in five different sizes: 3. With the average US home using about 30 kWh of electricity each daya kWh backup system is large enough to use for emergency power, but the smaller options are really only enough for utility bill savings, not backup storage in the event of an outage.

So, for example, LG guarantees that the 3. However, if you get the Brightbox system through Sunrun, they will handle this for you. How can a battery do that? In many areas of the country, homeowners can choose to enter into something called Time of Use rates with their utility company. Under TOU rates, prices throughout the day. During peak times when electricity is in highest demand usually in the late afternoon and morningprices are high.

Around midday and at night, when everyone is sleeping or running around town, demand is less and prices are lower. With an energy storage system like the LG Chem RESU batteries, you can save cheap electricity either during those low-priced times or from your solar installation to use during peak times when utility rates are highest.

With batteries still a costly endeavor, you need to live in an area where utility rates are high enough for energy storage to make financial sense. Homeowners in CaliforniaHawaiiand New York are already adding storage to their solar installations and more installers are tacking energy storage onto their list of available options.

Could the LG Chem batteries make sense for your own home? Most homeowners across the US still enjoy low electricity prices, making it impossible to save enough money to justify installing battery storage.

LG Chem has yet to release any pricing data publicly, but as of September we found a few of their batteries for sale online, including the 6. You can only get Brightbox as part of a system installed through Sunrun, financed via cash or leasebut as of publishing Sunrun had not yet responded to our requests for pricing details. High Voltage 9. Low Voltage 6. Tesla offers their Tesla offers a similar year warranty on the Powerwall, with no limit on the number of cycles.

Of course, neither of these figures include battery installation, so your total cost will be higher in real life. Still, you can quickly see which one makes more financial sense.

Of course, the calculations above are based on battery costs from online retailers. In real life, LG Chem assuredly offers wholesale prices to large installers like Sunrun. But without knowing exactly what LG Chem and Sunrun charge, we can only make educated guesses. The easiest way to see if the LG Chem battery makes sense for you? Contact Sunrun or another installer for cost and savings estimates.

Due to their high cost, solar batteries for grid-connected homes are still a niche product at the moment.
