SolaX X3 MEGA G2 40kW 3-Phase Inverter
Key benefits
- 40kW three phase string inverter for commercial roofs, ground-mount arrays and C&I sites needing efficient, grid-tied solar generation.
- Up to 150% PV oversizing and 110% overloading output, helping maximise yield where roof space or array size is constrained.
- Six MPPTs with up to two strings per tracker, supporting complex layouts and mixed orientations while maintaining good tracker control.
Brief description
The SolaX X3 MEGA G2 40kW Three Phase Inverter is designed for larger commercial and industrial PV systems that require high efficiency and flexible string design. With a wide 180–1000V MPPT range, up to 150% PV oversizing and smart air cooling, it fits well on medium to large roofs, carports and small solar farms. Built-in export power control, remote settings and I‑V curve diagnosis make ongoing management and maintenance more straightforward for installers and facility teams.
Key features
- Maximum efficiency up to 98.4% with European efficiency of 98.1% for strong energy harvest on three phase systems.
- DC input up to 1100V, 180–1000V MPPT range, 4 MPPTs and 2 strings per tracker on the 40kW model.
- Fuse-free design with smart string current monitoring and optional Smart I‑V Curve Diagnosis for easier fault detection.
- IP66 protection, Type II AC/DC surge protection as standard, with optional Type I+II SPD and AFCI for higher protection levels.
- Built-in export power control, remote setting and upgrading, aluminium AC cable option and optional PLC communication for flexible integration.
