A summary of the components:
DC terminal point:
Two PV strings can be 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. External fusing may be required, refer local and national electric codes.
DC disconnect:
In order to be able to disconnect the inverter on the PV generator side from sources of voltage, the inverter comes equipped with an
pre-installed DC disconnect switch. As a result, the installation of an external DC disconnect switch is not required. NOTE: Be sure to
check with local electrical codes and utility requirements as some inspectors will require a separate visible blade disconnect.
AC disconnect:
In Order to be able to disconnect the inverter on the grid side from sources of voltage, a AC disconnect switch is required.
Line overcurrent protection:
In order to protect the wiring, the inverter’s supply leads should be secured with circuit breakers or fuses as appropriate. The circuit
breakers or fuses that are used should be appropriate to the length and cross-section of the wiring and fulfi ll applicable standards and
directives (5.3: Electrical connection – grid connection).
Utility power meter:
The required utility power meter is specifi ed and installed by the responsible power company.
Main circuit breaker:
Contact your utility and check with local and national electrical codes if you have questions concerning the required main circuit breaker.
