The industry standard for whole-home backup. The Sol-Ark Limitless 15K delivers 12kW continuous, 13kW for 30 minutes and a 24kW surge to start central AC, well pumps and compressors. It supports both DC- and AC-coupled solar, transfers in 5ms, and its 200A grid passthrough can avoid a main-panel upgrade. A Smart Load output and 19.2kW GEN port round out a complete all-in-one PCS platform, with no MID required.
