5.2 INSTALLATION OPTIONS
This section explains optional items that may be required for
local regulations or personal wishes.
5.2.1 Functional grounding
During normal operation, the Soladin Web will balance the
DC voltage on its connectors around the PE potential. This
means the negative DC terminal will operate on a negative
potential with respect to PE and vice versa for the positive
DC terminal. Certain PV module types cannot withstand this
balanced operation and may suffer accelerated degradation
in case the array is left floating. In such a case, one of the DC
connectors of the PV array must be grounded. This is called
Functional Grounding. In case of functional grounding, the
Soladin Isolation detection has to be switched off to prevent
unneccessary alarms.

5.2.2 Using an RCD
If local requirements prescribe the use of an RCD, according
to IEC 60364-7: 712.413.1.1.1.2 (and local norms derived
upon this ) the Soladin Web is a “PV power supply that has at
least a simple separation between AC side and DC side”.
5.2.3 External DC Switch
Optionally the Soladin can be equipped with an external
DC switch which is used to disconnect the photovoltaic
modules from the inverter, as may be required in buildings by
the international standard IEC60364-7-712. It is available at
Mastervolt.
5.2.4 Connection to a 230V 3_Phase grid
If the public grid is in a three phase 230V Delta configuration,
the Soladin must be connected between two phases.
5.2.5 Load disconnection
Install a separate circuit breaker for each Soladin to ensure
that it can be disonnected safely when under load. 16A is the
maximum permitted fuse protection.
5.2.6 Changing country setting and advanced settings
For changing your country setting after setup and for
advanced settings, you need an installer password. This is
available at Mastervolt.
