– 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.
Safety | 2 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 oper- ator.
A potential-free relay contact is integrated into the device. Use this contact for one of the following functions: Page 10 KACO blueplanet 87.0 TL3 KACO blueplanet 92.0 TL3 KACO blueplanet 105 TL3 KACO blueplanet 110 TL3 KACO blueplanet 125 TL3 KACO blueplanet 137 TL3 KACO blueplanet 150 TL3 KACO blueplanet 155 TL3 KACO blueplanet 165 TL3...

Digital inputs It is possible to enhance the device with additional digital inputs by way of an expansion module (avail- able from KACO Customer Service). This can be used to connect a ripple control receiver or a protec- tive shutdown system.
In no condition the design may result in a greater short circuit current than ISCmax of the in- verter.Configuring the PV generator [See section 7.6.2} Page 29]. KACO blueplanet 87.0 TL3 KACO blueplanet 92.0 TL3 KACO blueplanet 105 TL3 KACO blueplanet 110 TL3 Page 13...
Depending on the local installation specifications, it may be necessary to earth the device with a sec- ond ground connection. To this end, the threaded bolt on the underside of the device can be used. KACO blueplanet 87.0 TL3 KACO blueplanet 92.0 TL3 KACO blueplanet 105 TL3 KACO blueplanet 110 TL3 Page 33...
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 dis- played in segment 2, for example.
M. As can be seen in the figure, a string combiner is assigned to each KACO device. In terms of communica- tion, these are coupled in directly to the device via an RS485 cable (green cable). MODBUS RTU is used as the communication protocol for this purpose.

It is preferable to install this on a plant component. It is also possible to select an NTP server local- ized 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 41...

– 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 rec- ommends establishing a connection via WiFi. 2. The device's communication circuit board has 3 Ethernet ports that can be used: 1.

Fig. 57: 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. NOTE: When multiple Segment Controllers are present, keep in mind that the Segment Con- trollers must not be connected to one another via the network during start-up.

Start-up | 8 Scope of application The network infrastructure is available in full. All of the KACO devices in the segments can be reached via Ethernet using the Segment Controller assigned to them. All Segment Controllers are monitored by a central Plant Controller.
It is only possible to configure the grid parameters with DC voltage. The further parameters can also be configured with a present AC voltage. KACO blueplanet 87.0 TL3 KACO blueplanet 92.0 TL3 KACO blueplanet 105 TL3 KACO blueplanet 110 TL3 Page 71...

This function ensures that grid support is provided by reactive power as soon as the voltage actually deviates from the target voltage. In this case, a characteristic curve is specified which KACO blueplanet 87.0 TL3 KACO blueplanet 92.0 TL3 KACO blueplanet 105 TL3 KACO blueplanet 110 TL3 Page 77...

If the ramp time “WMacLimPct_RvrtTms” in the SunSpec model is specified as 0 s, then the internal output gradient is used. Otherwise, the set value will be used. KACO blueplanet 87.0 TL3 KACO blueplanet 92.0 TL3 KACO blueplanet 105 TL3 KACO blueplanet 110 TL3 Page 81...
If a reduction in power occurs, the power is brought back up to the pre-fault level within 100 ms of the voltage returning. KACO blueplanet 87.0 TL3 KACO blueplanet 92.0 TL3 KACO blueplanet 105 TL3 KACO blueplanet 110 TL3 Page 87...

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 avail- able.
