What LS Energy Solutions does
LS Energy Solutions is a Charlotte, North Carolina-based designer and supplier of grid-connected energy storage systems founded in 2008. Originally the Energy Grid Tie Division of Parker Hannifin, the company was acquired by LS ELECTRIC in 2018 and operates as a wholly-owned subsidiary within South Korea's $25 billion LS Group. The company pioneered the first commercial lithium-ion energy storage installation in 2008 and has deployed more than 1.5 GW and 2.6 GWh across over 300 projects on six continents, supported by a portfolio of 90 patents.
The company's core technology centers on bidirectional string inverters and modular, containerized all-in-one energy storage systems. Its flagship AiON-ESS product line combines fourth-generation string inverters with Tier-1 lithium-ion batteries in factory-integrated enclosures available in Power Series (1-hour) and Energy Series (2-6 hour) configurations, scaled from 150-kVA to multi-MW. The underlying AiON-SIS inverter features a patented ability to parallel on both AC and DC sides up to 3 MVA, with optional grid-forming capability for microgrid applications. A modular DC bus architecture reduces short-circuit risk and enables mixing of battery generations and chemistries. Complementary products include the MSSP GEN 2.0 utility-scale inverter and a Fleet Controller/EMS for intelligent asset dispatch.
LS Energy Solutions sells primarily through a direct enterprise field-sales motion targeting utilities, project developers, and large commercial and government customers. Revenue is generated through hardware sales of integrated systems (AiON-ESS) and components (AiON-SIS inverters and balance-of-system parts), complemented by long-term operational services including commissioning, preventative and capacity maintenance, extended warranties, and remote monitoring bundled with major project sales. Pricing is quote-based and project-specific with multi-year contract cadences. The customer base spans independent power producers and storage funds (Gore Street Energy Storage Fund), municipal/nonprofit utilities (Citizens Energy/Wellesley MLP), commercial developers (Strata Clean Energy, V20 Energy, AES), and government/military (U.S. Army Fort Detrick via Ameresco). Products carry UL9540, UL1741, and NFPA 855 certifications.

LS Energy Solutions product offering
Product offeringCore offering
LS Energy Solutions designs, manufactures, and sells grid-connected energy storage systems combining proprietary bidirectional string inverters with lithium-ion batteries in modular, containerized configurations. Its flagship AiON-ESS all-in-one systems and AiON-SIS inverters are deployed in utility-scale, behind-the-meter, and microgrid applications across North America and globally.
Product overview
LS Energy Solutions provides a portfolio of energy storage solutions centered on two core product lines: the AiON-ESS all-in-one integrated systems and the AiON-SIS string inverters. The AiON-ESS family offers containerized AC energy storage in two variants—Power Series for 1-hour applications and Energy Series for 2-6 hour applications—combining LS's fourth-generation string inverters with Tier-1 lithium-ion batteries in modular, scalable enclosures. The AiON-SIS serves as the fundamental building block, a bidirectional string inverter that can parallel on both AC and DC sides up to 3MVA, with optional grid-forming capability for microgrid applications. The product portfolio also includes utility-scale inverters like the MSSP GEN 2.0. All systems are backed by comprehensive service, commissioning, and aftermarket support.
