M90U-80 vs Riello Multi Power2 M2U 68
The Xtreme Power M90U-80 supports up to 80 kW within a single cabinet, with an integrated maintenance bypass and published internal runtime data. The Riello Multi Power2 M2U 68 supports modular expansion up to 68 kW within its rated configuration. For facilities requiring higher usable capacity and a standardized service architecture, the M90U-80 provides greater lifecycle value.
What the M90U-80 brings
- Higher maximum usable capacity (80 vs 68 kW).
- Published internal runtime at maximum load.
- Integrated maintenance bypass as standard (vs optional / external).
- Modular static switch for service-friendly design.
- Clear, published warranty coverage.
