Prime+ will officially launch in the U.S. in May to meet the ever-growing needs of installers and homeowners for residential energy storage systems powered by LGES batteries. Prime+ is the first residential energy storage system including an inverter that LGES will launch in the North American market under its own brand name.
The Prime+ storage solution connects two 10H or 16H Prime battery modules in parallel to offer a capacity of 19.2-32kWh, with a maximum output of 9.6kW from the inverter. The simple modular architecture of the batteries and the plug-and-play design of the inverter ensure easy installation and unparalleled compatibility with any existing PV systems.
“What makes Prime+ unique is that the installation process is faster than ever. It takes less than 10 minutes for full inverter and battery commissioning, substantially lifting the time burden for the installers,” said Ryan Simpson, Sales Director of LGES ESS Team in North America.
The full compatibility with the existing PV systems makes Prime+ ideal for any American homeowner looking for retrofit options for partial or whole home backup. Particularly, the new solution is expected to benefit California residents, as the third iteration of net energy metering (NEM 3.0) took effect in mid-April.
Prime+ is offered in two configurations – the backup solution and the arbitrage solution – so that the customers can easily choose the right one to best satisfy their needs. The backup solution includes the Prime battery, the inverter, and an auto backup device, whereas the arbitrage solution includes the Prime battery, the inverter, and a smart meter. Specifically, if the customer wants to operate Prime+ for self-consumption only, then arbitrage solution will be the right one since it is more cost-effective than the backup solution.
Prime+ comes with a 10-year warranty for the batteries, as well as for the inverter and the auto backup device, to ensure durability and complete customer satisfaction.
LGES is hosting pilot sites with installers across multiple locations in different parts of America ahead of the official launch to give them the opportunity for hands-on experience of the new cutting-edge energy storage system.
