LG was founded 1958 and originated as a producer of radios, TVs, refrigerators, washing machines, and air conditioners. LG has recently started to make quality Solar batteries such as the RESU 7H. LG has four different business districts Home Entertainment, Mobile Communications, Home Appliances & Air Solutions, and Vehicle Components. The factories in Korea produce the RESU 7H. The company was established after the Korean war as a way of providing products for the Korean people at an affordable price. During the past 50 years, LG has expanded and bought a number of smaller companies from all over the world.
The RESU 7HLV is a Korean made solar battery pack, containing cells made by the company Longi and contains 6.6 kWh and can be installed alongside a RESU10H with a capacity of 9.8kWh. The RESU7H use an NMC based cell (lithium nickel manganese cobalt oxide) this improves their specific energy as well as prolonging their lifespan and is the cell type of choice for electric cars such as Nissan Leaf, Chevy Volt and BMW i3. It also has a runaway temperature of 210 °C and has been recently increased its market share. Due to the way the cells within the RESU 7H have been placed the risk of a safety issue is very low. Due to the RESU 7H’s fairly flat frame, it can be mounted on the side of a garage or driveway without the risk of being hit by a car. The battery has a water resistance rating of IP55. And is cooled via natural air flow that blows onto the slit-shaped battery’s that have the maximum surface area in order to make sure that the battery’s heat up as little as possible.
