Product Overview
The Elios 15kW converts solar DC power to three-phase 320-478VAC output for self-consumption or grid export. Three independent MPPT controllers allow the inverter to manage three separate string inputs optimally, which is particularly useful on commercial roofs with multiple orientations or partial shading across different roof sections.
The fanless cooling design eliminates moving parts entirely. Natural convection through the large aluminium heatsink maintains safe operating temperatures without noise or maintenance, making the inverter well suited to noise-sensitive commercial environments.
The CT clamp export limiting function allows the inverter output to be adjusted in real time to match consumption, enabling zero-export or a fixed export level as required by the DNO. Monitoring is available via Wi-Fi app or via a Solar Assistant Orange Pi controller for more advanced local and remote monitoring.

Installation and Safety Notes
Must be installed by a qualified electrician or MCS-accredited solar installer. Three-phase grid-connected inverters in the UK require G99 application and DNO approval before connection. All DC isolators, AC protection, surge protection, and earthing must comply with BS 7671. CT sensors must be installed by a qualified electrician. Do not attempt DIY connection of three-phase grid-tied equipment.
