Sol-Ark

What Sol-Ark does

Sol-Ark, LLC is a US-based manufacturer of hybrid solar inverters and lithium battery energy storage systems (BESS) serving residential and commercial/industrial customers. Founded in 2013 and headquartered in Allen, Texas, the company employs between 101 and 250 people and operates primarily through an indirect channel model centered on its certified Installer Corps network, with supplementary authorized distributors, battery partners, and a direct e-commerce storefront. The product portfolio spans residential hybrid inverters (12K-2P, 15K-2P, 18K-2P and the newer Limitless 12K-2P-LL), commercial hybrid inverters (30K-3P-208V and 60K-3P-480V), the L3 Series LimitLess modular lithium battery platform (HV-40, HV-60, HVR-60) with built-in aerosol fire suppression, and supporting accessories including CT sensors, connectivity dongles, and diagnostic tools.

The company's core technology centers on proprietary American-engineered firmware combined with hybrid inverter architectures featuring DC-to-DC conversion, native AC and DC coupling support, battery-agnostic compatibility with any 48V battery, 5ms grid-to-backup transfer time, and optional EMP hardening exceeding military standards. The MySolArk cloud-based energy management platform, hosted on US-based AWS infrastructure, provides real-time monitoring, system commissioning, fleet management, and Virtual Power Plant (VPP) integration. Sol-Ark positions its products as US-manufactured and FEOC-compliant, aligning with procurement preferences for critical infrastructure.

Revenue is generated primarily through one-time hardware sales of inverters, batteries, and accessories, with a small but unquantified portion represented by the 4G dongle's bundled cellular data plan. Pricing is not publicly disclosed; the flagship 18K-2P residential inverter requires a $500 non-refundable deposit due to allocation-constrained demand. The company targets residential homeowners seeking backup power and energy independence, commercial and industrial customers with high demand charges and decarbonization goals, and selected enterprise clients including Fortune 50 companies, defense organizations, and a major space agency. The company is privately held with no disclosed institutional investors, funding rounds, or ownership changes.
