– When working on the PV generator, it is also necessary to switch off the DC voltage with the external DC isolator switch (e.g. at the string combiner or the KACO DC switchbox) in addition to disconnecting the PV generator from the grid.
The device is intended for indoor and outdoor applications and may only be used in countries for which it has been approved or for which it has been released by KACO new energy and the grid operator. Operate the device only with a permanent connection to the public power grid. The country and grid type se- lection must be commensurate with the respective location and grid type.
The potential-free relay contact closes as soon as there is a fault during operation. You use this function, for ex- ample, to signal a fault visually or acoustically. KACO blueplanet 87.0 TL3 KACO blueplanet 92.0 TL3 KACO blueplanet 105 TL3 KACO blueplanet 110 TL3 Page 9...
The device features two RS485-Interfaces. One RS485-Interface is earmarked for communication with a string- combiner-box. This can be controlled using the Modbus RTU protocol. Data loggers that cannot be connected via Ethernet can be connected to the other RS485-Interface. The Sunspec and KACO protocol are supported in this case.

Within a segment, the KACO devices can be coupled to one another via the integrated switch in an Ethernet daisy chain, whereby the segment controller is connected to the first element of the chain. This topology is displayed in segment 2, for example.

– Ethernet cable (uncrossed patch cable) Establishing a connection to the KACO device 1. The device must be opened in order to connect the Ethernet cable! For safety reasons, KACO therefore recommends establishing a connection via WiFi. 2. The device's communication circuit board has 3 Ethernet ports that can be used: Page 40 KACO blueplanet 87.0 TL3 KACO blueplanet 92.0 TL3 KACO blueplanet 105 TL3 KACO blueplanet 110 TL3...

The device can also be operated without an external Segment Controller or data logger. In this case however, the internal logging options are limited and log data are only available for a certain period of time.

Fig. 48: Start-up via Segment Controller Area of application The network infrastructure already exists. All of the KACO devices in the segment can be reached via Ethernet using a Segment Controller. If the device serial number features a “.” dot, then this “.” dot is replaced with a “-” dash in the host name as, according to RFC229, host names must not contain any “.”...

Area of application The network infrastructure is available in full. All of the KACO devices in the segments can be reached via Ether- net using the Segment Controller assigned to them. All Segment Controllers are monitored by a central Plant Controller.

It is preferable to install this on a plant component. It is also possible to select an NTP server localized on the internet provided the device has direct access to the internet. KACO blueplanet 87.0 TL3 KACO blueplanet 92.0 TL3 KACO blueplanet 105 TL3 KACO blueplanet 110 TL3 Page 45...
It is only possible to configure the grid parameters with DC voltage. The further parameters can also be con- figured with a present AC voltage. KACO blueplanet 87.0 TL3 KACO blueplanet 92.0 TL3 KACO blueplanet 105 TL3 KACO blueplanet 110 TL3 Page 69...

(PT-1) with a time constant of Tau=200ms. The specified reactive power can be configured on the display or by way of communication via the KACO RS485 protocol and MODBUS/SunSpec. If the applicable grid code stipulates that the reactive power should react to the target value slower than the configured Tau=200 ms by way of a defined gradient or settling time, this gradient or settling time must be im- plemented in the system control.
Some grid connection rules insist that the agreed reactive power be supplied from every operating point of the plant without a reduction in the actual active power. Considering the fact that all KACO TL3 inverters have a semi-circular P-Q operating range, a reduction in the active power is, however, required during operation at maximum active power because an apparent power reserve is not available.
Enhanced island detection method The new method by KACO new energy, enhanced island detection, employs a strategy to reliably detect island formation that is based on the characteristic differences between an interconnected grid and an islanded grid, thus ensuring reliable fast detection and prevention of false tripping.
