EAI Series Solar Inverter

The EAI series Solar Inverter converts DC power generated by airport photovoltaic installations into 115 V, 400 Hz three-phase aviation-grade AC output — the first link in a solar-powered ground support power chain. Aviation ground power traditionally requires either a utility-connected frequency converter (which depends on the quality and availability of the grid) or a diesel generator (which has fuel and emissions costs). The EAI positions renewable solar energy as a third source, directly producing the 400 Hz output standard without an intermediate 50 Hz grid stage. This is architecturally significant: the EAI enables fully off-grid aircraft power supply where solar resource is adequate and a battery buffer is available, which makes it relevant to remote airstrips, temporary operating bases, and eco-aviation infrastructure at airports committing to on-site renewable generation. The compact modular design is optimised for outdoor airport environments, and the simple architecture is intended to reduce maintenance requirements relative to diesel or rotary converter alternatives. For procurement teams evaluating the long-term cost structure of apron power infrastructure, the EAI represents the renewable generation endpoint of the ElectroAir power chain — the upstream origin of electrons that ultimately reach the aircraft connector through converters, pits, and cables.
