LG Energy RESU 10H Prime and 16H Prime

LG Energy Solution was born from LG Chem, a company founded in 1947 in Korea, in 1992 it began the development of lithium-ion batteries becoming one of the best manufacturers and suppliers of batteries worldwide.

Since 1999 it has started the mass production of lithium-ion batteries, expanding and enlarging in various world countries.

In 2009 its batteries are used in the first mass-produced electric vehicle in the world and from 2010 the ESS battery business begins for the accumulation of energy for residential use with the first RESU.

World No. 1 leader in the battery sector especially for electric vehicles with numerous tests carried out by major car manufacturers including Ford, GM and Volkswagen. It uses a patented technology called SRS® (Safety Reinforced Separator) and a cell production process “ Lamination and Stacking (L&S)”, making them reliable, stable and long-lasting.

RESU Prime domestic batteries

In the production of lithium batteries for domestic use we find the high voltage RESU Prime 10H and 16H series. Their modular design (in a control unit and 2 battery modules) allow a better management during transport and assembly and greater safety with separate battery packs reach a capacity of 9.6 kWh and 16 kWh with a discharge of 5 kW and 7 kW. Furthermore,  batteries are parallelable, up to two units, reaching a capacity of:

  • RESU 16H x 2ea: capacity 32 kWh, power 14 kWh
  • RESU 10H x 2ea: capacity 19.2 kWh, power 10 kWh

The IP55 degree of protection allows the battery to be installed both indoors and outdoors, provided, it is always protected from atmospheric agents. Compatible with SolarEdge inverters.

NEW: from June, RESU Prime will also be compatible with LG Energy Solution’s single-phase HV hybrid inverter.

Registration: through the RESU Monitor app it is possible to register the PRIME batteries and connect them to the internet.

The RESU PRIME can be controlled remotely, through the app, facilitating maintenance and reducing costs.

Warranty extendable from 5 to 10 years

The warranty can be extended from 5 to 10 years. To be entitled to 10 years, the installer must connect the battery to the internet during registration and obtain the certified installer document.

LG Energy Solution prepared videos, available at any time, to help the installer pass the test and improve his/her work.


LG Energy Solution PRIME – high voltage – 10H/16H

LG PRIME offers maximum safety for electricity consumption regardless of external uncertainties, achieving energy independence through the conservation of self-produced and eco-friendly solar energy.

  • It works in temperatures ranging from -10°C to 50°C, so it is suitable for any type of weather conditions.
  • The installation can be done both on the wall and on the floor.
  • Available sizes: PRIME 10H, PRIME 16H.

With LG PRIME, the high energy capacity and power output allow the entire home to be backed up during both peak hours and blackouts.

The detachable control unit can be replaced on site, saving time and maintenance costs.

With RESU Monitor it is possible to monitor the battery status in real time and perform diagnostics to detect anomalies.

As for transport and installation, there is no need for a lift to load/unload from the truck and 1-2 installers are required to assemble it.

Ease of transportation is allowed thanks to the modular design, as it can be divided into battery control units and two battery modules.

70% of useful capacity is guaranteed in the tenth year.

LG PRIME batteries are characterized by their modular design. This simplifies transport but also handling and installation and maintenance on-site.

LG Energy Solution also debuted its LG RESU FLEX concept design which is characterized by ease of installation and scalability. RESU FLEX is a hybrid, flexible product that allows the free arrangement of battery units in different geometric ways to build a battery system that provides a customized capacity with a customized design. The FLEX series is designed to consist of even smaller battery cells than JH5 ​​technology, does not require a converter, and will be compatible with hybrid inverters from brands such as Kostal or Fronius.

Both batteries can be connected in cascade with another unit of the same power class and size. This means that the RESU16H Prime can be scaled up to 32kWh with double the power of 14kW and the RESU10H Prime can be scaled up to 19.2kWh with double the power in total 10kW.

The individual battery modules of the storage unit weigh 41 kg each for the 10H model and 65 kg for the 16H model. The control unit and the base plate required for installation weigh another 30 kg.
