7 PRODUCT BANKABILITY Due Dilligence Reports Black & Veatch Black & Veatch has recently issued an independent assessment on the design and manufacturing process of Ingeteam central PV inverters. This assessment highlights the reliability and durability of Ingeteam inverters, as well as their ability to meet the market requirements. Astrom Technical Advisors Their clients include +300 top financial institutions, developers, first-line equipment manufacturers and equity investors all over the world. Ingeteam inverters were very well evaluated in regards to their efficiency, quality improvement and technology.

10 INVERTER PERFORMANCE Low voltage ride-through capability Capability of the inverter to stay connected to the grid and keep operation following voltage dips or surges. LVRT response at 100% nominal power

11 INVERTER PERFORMANCE Reactive power control Depending on the grid operator s requirements, the reactive power could be leading or lagging. Reactive power at night: At night, B Series inverters can shift to reactive power compensation mode.

12 INVERTER PERFORMANCE Power reduction in case of over-frequency Two different ways of reducing the output power in case of over-frequency: A A B B C C Example of power reduction performed by hysteresis Example of power reduction not performed by hysteresis A: frequency level at which power reduction starts. B: frequency level at which power injection returns to its nominal value. C: frequency level at which the PV inverters will stop supplying power to the grid.

13 INVERTER PERFORMANCE Power reduction in case of over-frequency Some standards require an active power reduction when frequency surpasses a certain threshold. Ingeteam ensures that the reduced output power remains stable at a fix level until the frequency recovers its rated value. Real example of power reduction in case of over-frequency.

17 SMART GROUNDING KIT Enhanced grounding monitoring system The PV array is grounded via circuit breaker connecting one pole (negative or positive, depending on the PV panel technology) to the ground. This kit will act as a smart monitoring system that will measure every morning the impedance of the PV array and will send an alarm in the event of an insulation failure.

18 ANTI-PID KIT Solution to avoid the potential induced degradation This kit prevents the degradation caused by stray currents in crystalline modules inside ungrounded photovoltaic systems, that can cause serious power losses. The anti-pid kit consists of a power supply connected between the ground and the negative pole of the PV array that applies a positive voltage to the PV array at night (with the AC contactor opened).
