3Power C Series

A three-phase central inverter family, with rated powers ranging from 3,325 to 3,825 kVA.

These high-efficiency PV inverters feature the highest power density in the market, apart from IP65 protection rating for the inverter's compartment that contains the power stack with the power phases, the IGBTs, the power and control electronics and all the DC and AC protections.

They have been designed to contribute to the quality and stability of the electric system, implementing several grid-support functionalities:

• LVRT/HVRT capability,
• Reactive power injection even during the night,
• Black start capability,
• Active power reserve without batteries (patented technology),
• Voltage droop control,
• Fast frequency regulation,
• Automatic voltage regulation,
• Grid Following & Grid Forming operating modes.

Latest generation electronics

The 3Power C Series solar PV inverters integrate an innovative control unit that runs faster and performs a more efficient and sophisticated inverter control, as it uses a last-generation digital signal processor. Furthermore, the hardware of the control unit allows some more accurate measurements and very reliable protections.

Maximum efficiency

Through the use of innovative electronic conversion topologies, efficiency values of up to 98.9% can be achieved. Thanks to a sophisticated control algorithm, these PV inverters can guarantee the maximum efficiency depending on the PV power available.

Integrated accessories:

• Motorized DC switch to automatically disconnect the inverter from the PV array.
• Motorized AC circuit breaker.
• Lightning induced DC and AC surge arrestors, type II.
