The inverter automatically senses the phases connected to it. When wiring the system to the utility grid it
does not matter which of the red, blue or orange wires are connected to which phase. However, a fault
will appear if the neutral (white or grey) wire is connected to one of the phases. This is the same fault that
will appear if one of the three phases is disconnected. These conditions will not damage the inverter but
should be corrected.
If one of the phases is not connected, the web and touch screen views will show one of the AC phases faulted
rather than all three.
If the neutral is connected to one phase, the power line communications to the Gateway may not work.
CAUTION: Hazard to Equipment
If the inverter is connected to the wrong voltage system, such as 480 Vac 3-phase,
damage is likely to result. The system will need to be returned to the factory.
(E) Inverter Installation Issues
i)
Unterminated connectors allow moisture to ingress
ii)
Inverter in direct sun and temperature range exceeded, causing output to be reduced due to high
internal temperatures. This protective feature helps to extend the lifetime of the inverter.
The inverter is NEMA6 rated and very robust. To maximize reliability and performance for the longest lifetime
it should be mounted vertically in the shade and bolted to metal racking if available. However, it can be
ballast-mounted in the shade. If the device is placed in a situation where it exceeds its rated temperature
range it will reduce output power slightly until it is safely back within the operating temperature range.
As with all such devices, NEMA6 waterproof operation requires that all connectors, whether used or unused,
be properly terminated. If this is not the case, moisture may ingress, causing the unit to eventually fail.
(F) PV Module Wiring Issues
i)
PV module not connected
ii)
PV module wiring fault
iii)
Faulty wiring or connectors not fully engaged
iv)
Missing PV module
These are generally self-explanatory issues of connectors not engaged or damaged wiring.
