About LG Chem
LG Chem is ranked as one of the world’s largest lithium-ion battery manufacturers with over 29,000 employees worldwide, manufacturing a diverse range of energy storage products for solar systems, electric vehicles, portable electronics and stationary applications. This large range of lithium battery systems has positioned LG Chem as one of the industry leaders in residential and commercial solar energy storage.
RESU Battery Series
The latest RESU (Residential Energy Store Unit) battery series by LG Chem owes its success to a number of factors such as the unique cell design, performance, compatibility, safety and service backed by a huge multi-national company. Their 48V (LV) series is available in 6.5kWh, 9.8kWh, 13kWh sizes. Larger systems (a maximum capacity of 19.6kWh) can be achieved by using two battery units, using the LG RESU plus battery combiner unit called the ‘RESU Plus’.
As opposed to many other battery manufacturers, LG Chem uses a unique Polymer ‘pouch’ flat laminated battery design (PH3), claimed to enable higher energy density with increased reliability and safety. Layering the battery cell sections reduces the possibility of failure, enabling even heat dissipation across the cell area.
LG Chem features industry-leading depth of discharge rates and DC round-trip efficiency. Depth of discharge refers to the percentage of battery energy that has been discharged relative to the overall capacity of the battery. Unlike other battery options on the market that utilise approximately 80% of their storage capacity, the latest 4th generation LG Chem RESU’s boasts a depth of discharge rate of up to 95% across all battery sizes. The DC round-trip efficiency is the measure of electrical losses involved in charging and discharging the battery; the higher the efficiency percentage, the more efficient the battery is in converting incoming electricity into usable power. The LG Chem RESU series also has a phenomenal 94.5% round-trip rate, meaning that for every 10 kilowatt-hours (kWh) of electricity charged into the battery, you’ll receive 9.45kWh of output.
Its design allows easy wall-mounted or floor-standing installation for both indoor and outdoor applications. The inverter connections have also been simplified, reducing installation time and costs. LG Chem has been working closely with inverter manufacturers to ensure that their product is compatible and easily configurable with almost every popular hybrid and off-grid battery inverters on the market. When installed with a compatible EPS (Emergency Power Supply) device, your battery will power critical devices such as your lights, fridge, security system, healthcare devices etc in the event of a blackout.
All LG Chem RESU batteries are IP55 weather rated, allowing them to be installed in semi-outdoor locations such as a veranda or carport, though should not be located in a position exposed to direct sunlight to comply with both compliance and warranty criteria. As with any electrical/battery system, excessive prolonged heat is detrimental to the performance and life of the system. The RESU series are tested to the UL1973 test standard which requires there to be no explosion or sign of fire when the cells are forced into a thermal runway condition.
The LG chem RESU warranty is 10 years, based on 2 main factors – the remaining capacity and energy throughput based on charge and discharge cycles. All batteries reduce capacity over time due to internal cell degradation, this is not a flaw in the product quality. The LG chem warranty ensures the retained storage capacity is “at least 60% of the Nominal energy (original amount) for either 10 years after the date of the initial installation or for a minimum Energy Throughput”.
