Operation
38
• High
Battery
– In the event the battery voltage approaches the
High Battery Cut Out (
HBCO
) level, the inverter will automatically
shut down to prevent the inverter from supplying unregulated AC
output voltage. The INV LED turns off when a high battery fault
condition occurs. The inverter will automatically restart when
the battery falls to the High Battery Cut In (
HBCI
) level. Refer
to Table 4-2 to determine the HBCO and HBCI levels for your
particular inverter model.
Info:
High battery voltage may be caused by excessive
or unregulated voltage from solar panels or other
external charging sources.
• Overload
– During Inverter and Standby operation modes, the
inverter monitors the DC and AC current levels. In the event
of a short-circuit or an overload condition for more than a few
seconds, the inverter will shut down. To start operating after
this fault, the inverter would need to be restarted (turned back
on) after the inverter’s AC loads are reduced/removed.
• Over-temperature
–
If internal power components begin to
exceed their safe operating temperature level, the inverter will
shut down to protect itself from damage. The inverter’s status
LED turns OFF to indicate the over-temperature fault condition.
The inverter will automatically restart after the units cools down.
• Internal
Fault
– The inverter continually monitors several
internal components and the processor communications. If a
condition occurs that doesn’t allow proper internal operation,
the inverter will shut down to protect itself and the connected
loads. The inverter will need to be reset to start operating.
