In industrial applications quality plays a decisive role. System design and integration is not an empty phrase for ALFA UPS. Its central inverters named the Power PV.250, PV.560, PV.690 and PV.880 stand for innovation and quality for utility-scale solar power plants. The control circuity is fully digital and communication- enabled, so parameters can also be monitored and controlled remotely via the Internet. ALFA UPS solar inverters include such features as low-loss chokes, high-quality components and double-coating of all PCBs. This forms the basis for decades of reliable operation.
