6
HI AC AMPS
The
Inverter
current
exceeded
beyond
limit.
The system has detected a
high current or dc voltage
d i s t u r b a n c e a n d h a s
temporarily shut down. This
fault is similar to a current
limit fault except that it could
not be traced to a specific
line. This fault could also be
caused if the battery voltage
rises above the hardware
protection but is still below
the high dc voltage setting.
16. Carry out Fault Reset
17. Contact Technical Support.
18. Note: The inverter will attempt
restart 3 times after every 1
minute to clear this fault. If fault is
not cleared the inverter will shut
down.
7
Low DC Volts
Battery is
heavily
discharged
This fault occurs when there
n o S o l a r a n d g r i d a r e
available for a long time.
Internal losses of the battery
down its gravity. Then battery
is not able to start the
inverter.
19. Charge battery immediately to
prevent permanent damage.
8
HI DC Volts
The
Battery
voltage
sensing is
reporting
an invalid
measurem
ent.
The battery voltage has
exceeded its safe high limit.
The solar regulator will be
tripped and if the fault
persists the source will be
masked. If the condition still
persists the inverter is
masked eventually.
20. Make sure that there are no
external DC sources (solar/wind)
that are not controlled by the
HBD-NG System that could cause
the battery to overcharge.
21. If fault continues contact
Technical Support

T h e i n v e r t e r h e a t s i n k
temperature on this system
is too high and the inverter
has shut down to protect
i t s e l f a g a i n p e r m a n e n t
damage. System gets tripped
and supply load in bypass
mode.
22 . Reduce the load for 15 minutes
so that temperature can lower.
23. Check for any wiring damaged.
24. Contact our Technical
personnel.

temperature on this system
is too high and the inverter

25. Reduce load and Wait 15
minutes for heat sink to cool and
carry out Fault Reset.
26. If fault continues contact
Technical Support
27. Note: The inverter will attempt
restart 3 times after every 1

Low AC Freq
Low AC
Source
Frequency
The frequency from the
source that was on-line was
too high and out of range and
t h e s o u r c e h a s b e e n
disconnected. If the source
was a generator then the
system will attempt to start
and connect to it four times. If
the fault is still present the
system selects another
generator as the source.
28. Repair or replace source.
29.If fault continue, contact
