3.2.5 Mechanical components
3.2.5.1 DC isolator switch
The DC isolator switch is used to disconnect the inverter from the PV generator in order to carry out service.
Disconnecting the inverter from the PV generator

3.2.5.2 Night start button
The unit switches off in the evening as nightfall approaches. At this point, nothing is shown on the display. In order
to retrieve the values from the current day (daily yield, daily hours of operation and max. feed-in power) after the
display switches off, the unit can also be activated during the night by pressing the night start-up button.

3.2.6 Interfaces
The inverter has the following interfaces for communication and remote monitoring:
•
RS485 interface
•
S0 interface
You configure the interfaces in the Settings menu (see section 8.3 on page 34).
3.2.6.1 Software for direct monitoring
Together with the Powador inverter, KACO-viso takes over the role of a data logger. It saves the data from the
inverter and displays it in various diagram types as a daily or monthly representation. The PC, however, must also
run continuously. Because of the amount of energy used, this type of monitoring only makes sense over limited
periods, such as during a fault analysis. For permanent system monitoring, we recommend the optional accessories
(Powador proLOG).
3.2.6.2 RS485 interface
Use this monitoring option if you cannot check the functioning of the system on-site on a regular basis, e.g. if your
place of residence is located a great distance from the system. To connect the RS485 interface, contact your author-
ised electrician.
For monitoring your PV system using the RS485 interface, KACO new energy GmbH offers the following units:
Powador-proLOG S to XL (optional)
Powador-proLOG allows you to monitor up to 31 inverters simultaneously. Depending on the product model, Pow-
ador-proLOG sends yield and operating data by SMS or e-mail.
Powador-link RS485 (optional)
Use the Powador-link RS485 to bridge long distances between several inverters or between an inverter and the Pow-
ador-proLOG by means of wireless radio transmission.
