SolaX X3‑AELIO 50kW HV Commercial 3‑Phase Hybrid Inverter
Key benefits
- 50kW three‑phase hybrid inverter for commercial and industrial sites needing reliable power from solar PV, high‑voltage LFP batteries and the grid in one system.
- Flexible configuration with support for up to 10 parallel systems and up to 200% PV oversizing, allowing designs from around 50kW up to 600kW with shared controls.
- IP66 protection, high efficiency (up to 98.0%) and rapid 10ms on‑grid/off‑grid transfer for demanding environments and critical loads.
Overview
The SolaX X3‑AELIO 50kW HV Commercial 3‑Phase Hybrid Inverter is part of the X3‑AELIO range (49.9kW / 50kW / 60kW / 61kW) designed for larger commercial and industrial applications. It manages energy flows between high‑voltage LFP battery storage, substantial PV arrays and the three‑phase grid, with optional generator integration and support for virtual power plant (VPP) applications.
Typical sites include logistics hubs, food production and cold stores, commercial buildings with critical three‑phase loads, and micro‑grids where fast switchover and extended off‑grid capability are required. Installation and commissioning should be carried out by suitably qualified three‑phase installers or via Energian’s trusted partners to ensure compliance with G99 and other local requirements.
Key features
- Parallel operation: supports up to 10 parallel systems, covering power requirements from 49.9kW to 600kW.
- Battery options and high‑voltage LFP battery input (180–820V) with up to 160A charge/discharge current (80A × 2).
- PV oversizing up to 200%, with up to 5 or 6 MPPTs (model‑dependent) and 2 strings per MPPT for array flexibility.
- 100% three‑phase unbalance support, 110% long‑term overload and 150% off‑grid overload capability.
- Remote monitoring via web/app, OTA updates, versatile operating modes (self‑consumption, peak‑shaving, demand management) and VPP integration via IEEE2030.5 and OpenADR (where available).
