Manufacturing Partner
Sol-Ark
Limitless Energy. Engineered in Texas.
Sol-Ark is a Texas-based engineering company building the hybrid inverter platform trusted by installers, utilities, and federal agencies across North America. Their inverters integrate solar, battery, grid, and generator into a single intelligent system — the same architecture Lumis deploys on nearly every project we build.


Our partnership
Lumis Energy is a certified Sol-Ark installation and service partner. We design, commission, and support Sol-Ark systems end-to-end — from residential 12K and 15K hybrid inverters in Texas homes to 60K-3P-480V three-phase platforms anchoring commercial microgrids. Our crews are trained on Sol-Ark's full product line and our service techs are equipped to handle warranty, firmware, and performance work in the field.
Why we partner with Sol-Ark
Whole-home and whole-facility resiliency
Sol-Ark hybrid inverters are designed for true islanding — keeping homes and businesses online during ERCOT events, hurricanes, and freeze emergencies.
Battery-agnostic platform
Sol-Ark's open architecture lets us pair the right storage with each project, including closed-loop integration with Renon Power LFP batteries.
Trusted at scale
Used by the U.S. Army Corps of Engineers, the Department of Defense, AT&T, Verizon, and thousands of homes and businesses across the country.
Local engineering, US support
Engineered and supported from Texas — the same state where Lumis designs, installs, and services every system we deliver.
