Kostal PIKO CI inverters for commercial, industrial and utility scale systems

Kostal expands its range with the introduction on the market of Kostal PIKO CI inverters in sizes 30, 50 and 60 kW, to serve medium-large plants.

Maximum flexibility and efficiency

The configuration of the photovoltaic generator is very flexible, the smaller size has 2 maximum power point trackers while the two bigger brothers have 4.

Thanks to the wide MPPT range with absolute maximum input voltage of 1100 V and the start voltage of 250 V, the system will come into service very early in the morning, producing the maximum possible energy throughout the day.

The maximum allowed overload is 150% while also ensuring economy.

Quick installation without string box

Installation is quick thanks to the possibility of not installing the string panels given the SPD Type 2 both on the DC side but also on the AC side and the integrated fuse holders.

The accessories included as standard are completed by the DC disconnect switch and the integrated Smart AC Switch.

Kostal PIKO CI with IP65 protection ideal for indoor and outdoor installations

The protection degree IP65 makes it perfect for both indoor and outdoor installations. The AC side connection is 4-wire without neutral.

Integrated WLAN and dedicated Kostal PIKO CI App

Commissioning is quick and intuitive thanks to the integrated WLAN and the dedicated KOSTAL CI app.

The data logger is built in and thanks to the optional antenna, the WLAN can be used for the transmission of monitoring data via the web portal or free Kostal apps.

There are also 2 LAN ports with integrated switch so the communication can be via in-out design.

RS485 communication interfaces

The communication interfaces are completed with RS485 for connection to third-party monitoring platform and plant controllers.

The new Kostal PIKO CI are also compatible with the Smart Energy Meter so as to be able to directly perform the dynamic limitation of the power fed into the grid.
