U B SERIES (1800kW/1500V)

These PV central inverters feature the greatest power density, as they are able to provide up to 1,800 kW in only one power block. This is possible thanks to their 1,500 Vdc technology.

The B Series inverters feature an improved AC busbar, facilitating the installation work and its connection to the MV transformer. These central PV inverters are equipped with a motorized DC breaker to decouple the PV generator from the inverter. Also, they are supplied with a motorized AC circuit breaker as standard. Optionally, they can be supplied with DC fuses, grounding kit and input current monitoring.

The 1,500Vdc U B Series 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 a more accurate metering. These PV inverters feature a lower power consumption thanks to a more efficient power supply electronic board.

• Grid support: these PV inverters feature a low voltage ride-through capability, and they can deliver reactive power and control the active power delivered to the grid.
• Maximum efficiency values of up to 99.1%.
• The maximum power is delivered up to 45ºC (113ºF) ambient temperature.
• It allows to ground the PV array.
• Advanced MPPT algorithm that makes it possible harnessing the maximum power from the PV array.
• Main protection devices supplied as standard.
• Standard 5 year warranty, extendable for up to 25 years.
• Ease of maintenance thanks to its modularity. If a power block fails, the power is then distributed amongst the remaining blocks.
• RS-485 communication supplied as standard.
• Various applications for monitoring and recording the inverter's internal operating variables are included at no extra cost: INGECON SUN Manager, INGECON SUN Monitor and its iSun Monitor Smartphone app.
