SolaX X3 MEGA G2 50kW 3-Phase Inverter
Key benefits
- 50kW three phase string inverter for larger commercial roofs, carports and C&I ground‑mount sites where reliable grid‑tied solar generation is required.
- Up to 150% PV oversizing and 110% overloading output to maximise yield and make better use of available roof or site area.
- Up to six MPPTs with two strings per tracker, giving flexibility for complex layouts, multiple orientations or partial shading.
Brief description
The SolaX X3 MEGA G2 50kW Three Phase Inverter is part of the X3‑MEGA G2 commercial range covering 40kW, 50kW and 60kW models. It offers a wide 180–1000V MPPT range, high efficiency and smart air cooling, making it suitable for medium and large commercial roofs, agricultural buildings and small solar farms. Built‑in export power control, remote configuration and Smart I‑V Curve Diagnosis help installers and operators manage performance and maintenance over the system lifetime.
Key features
- Maximum efficiency up to 98.4% with European efficiency of 98.1% for strong energy harvest on three phase systems.
- Rated 50kW AC output with up to 55kVA apparent power and up to 100A maximum AC output current depending on grid voltage.
- DC input up to 1100V, 180–1000V MPPT range, five MPPTs and two strings per tracker on the 50kW model.
- Fuse‑free design with smart string current monitoring and optional Smart I‑V Curve Diagnosis for easier troubleshooting.
- IP66 enclosure, Type II AC/DC surge protection as standard, with optional Type I+II SPD and AFCI for higher protection levels.
