Generator AC Wiring
Generators wired to the Sol-Ark must be rated at
240VAC
. Installations outside North America that
incorporate generators rated at 230VAC / 50Hz can be wired to the Sol-Ark, provided there is no Neutral
wiring connection.
Generators can either be wired to the Sol-
Ark’s Generator Input Port or to the Sol-Ark’s Bi-directional Grid
Port.
In grid-connected systems, generators cannot be wired to the Grid Port. However, the Sol-
Ark’s
Generator Input Port may need to be utilized for purposes other than the generato
r’s connection. AC
Coupled systems or systems utilizing the Sol-
Ark’s Smart Load functionality are wired to the Sol-Ark’s
Generator Input Port. In such scenarios, a whole-home generator transfer switch is necessary to
incorporate a generator into the system:
Figure 15.0 - Generator Wiring in Grid-Connected AC Coupled Systems
It is also acceptable, but not required, to use a whole-home generator transfer switch when the Generator
Input Port does not need to be utilized for an AC Coupled solar PV array or Smart Loads. This setup is
typical for larger (10-30 kW) generators.
In off-grid systems, Sol-Ark recommends that the Grid Port be used for generator connections.
CAUTION
:
Adhere to the programming instructions in the “Generators” sub-section of Section
5.3 (Configuring the Sol-Ark) in this Manual when incorporating a generator into the system.
Inverter Charger Grounding
The Sol-Ark includes a ground busbar (outlined in Figure 14.0). A wiring connection must be made
between the Sol-
Ark’s ground busbar and earth ground using appropriately sized equipment grounding
conductors. The Sol-
Ark’s ground busbar accepts wire sizes up to
4 AWG
. System grounding must be
done according to all applicable NEC and local installation codes.
