A summary of the components:
DC terminal point:
Two generator strings are connected in parallel either at a DC terminal point between the solar generator and the inverter or directly
on the inverter (terminals for three strings are provided on the inverter). Of course, you can also connect the strings directly to the solar
generator and then run just one negative and one positive lead to the inverter.
DC disconnector:
In order to be able to disconnect the inverter on the generator side from sources of voltage, the inverter comes equipped with an inte-
grated DC disconnector. As a result, the installation of an external DC disconnector is not required.
Line fuses:
In order to protect the leads, the inverter's supply lead should be secured with NEOZED fuses. The fuses that are used should be
appropriate to the length and cross-section of the leads and fulfi l applicable standards and directives (5.3: Electrical connection – grid
connection).
Grid-feed counter:
The required grid-feed counter is specifi ed and installed by the responsible power supply company. Some power supply companies also
allow the installation of your own calibrated counters. In this case, you do not need to pay rent for the counter, but the power supply
company may require that the counter be periodically calibrated.
Selective main switch:
Contact your power supply company if you have questions concerning the required main switch.
