Thanks to the 1,500 V technology and to an innovaive air cooling system which makes it possible to deliver the maximum power up to 50 °C, these new PV central inverters feature the maximum power density in a compact enclosure.

As well as the other INGECON® SUN PowerMax series devices, the new B series 1,500 V inverters integrate the DC and AC supplies in the same cabinet, facilitating maintenance and repair work. These three-phase inverters are equipped with a motorized DC breaker to decouple the PV generator from the inverter. They can be supplied with an AC circuit breaker in addition to fuses, grounding kit and DC input current monitoring.

Thanks to a sophisticated control algorithm, this equipment can guarantee maximum efficiency depending on the PV power available. Thus, 98.9% maximum efficiency values can be achieved. Furthermore, they have been designed to ensure a service life of more than 20 years, as demonstrated by the stress tests they are subjected to.

The INGECON® SUN PowerMax B Series has been designed to comply with the grid connection requirements in different countries, contributing to the quality and stability of the electric system. These inverters therefore feature a Low Voltage Ride-Through (LVRT) and High Voltage Ride-Through (HVRT) capability and can deliver reactive power and control the active power delivered to the grid.

The following applications are included at no extra cost: INGECON® SUN Manager, INGECON® SUN Monitor and its Smart-phone version iSun Monitor, available on the App Store. These applications are used for monitoring and recording the inverter’s internal operating variables through the Internet (alarms, real time production, etc.), in addition to the historical production data. Two communication ports available (one for monitoring and one for plant controlling), allowing fast and simultaneous plant control.

In the Outdoor version (IP56 protection rating), the fresh air intake is made from the top, thereby reducing the influx of particles and the obstruction of the filters.

Standard 5 year warranty, extendable for up to 20 years.
