Symptom
Possible Cause(s)
Recommended Solution(s)
Inverter will not turn on during
initial power up.
Batteries are not connected, loose
battery-side connections.
Low battery voltage.
Check the batteries and cable
connections. Check DC fuse and
breaker.
Charge the battery.
No AC output voltage and no
indicator lights ON.
Inverter has been manually
transitioned to OFF mode.
Press the switch to Power saver
on or Power saver off position.
Inverter overload indicator on
Excessive AC output load or AC
output short
Defective inverter
Check AC output loads and
wiring
Inverter high temperature
indicator on
Excessive ambient temperature or
AC output load
Check AC output loads, increase
ventilation, derate the inverter if
ambient temperature is excessive.
AC output voltage is low and
the
inverter turns loads OFF in a
short time.
Low battery.
Check the condition of the
batteries and recharge if possible.
Charger is inoperative and unit
will not accept AC.
AC voltage has dropped
out-of-tolerance
Check the AC voltage for proper
voltage and frequency.
Charger is supplying a lower
charge rate.
Charger controls are improperly
set.
Low AC input voltage.
Loose battery or AC input
connections.
Refer to the section on adjusting
the “Charger Rate”.
Source qualified AC power..
Check all DC /AC connections.
Charger turns OFF while
charging
from a generator.
High AC input voltages from the
generator.
Load the generator down with a
heavy load.
Turn the generator output voltage
down.
Sensitive loads turn off
temporarily when transferring
between grid and inverting.
Inverter's Low voltage trip voltage
may be too low to sustain certain
loads.
Choose narrow AC voltage in the
DIP switch, or Install a UPS if
possible.
Noise from Transformer/case*
Applying specific loads such as
hair drier
Remove the loads
*The reason for the noise from transformer and/or case
When in inverter mode and the transformer and/or case of the inverter sometimes may vibrate and make
noise.
The noise may come from transformer.
According to the characteristics of our inverter, there is one type of load which will most likely to cause
rattles of transformer, that is a half-wave load, load that uses only a half cycle of the power(see figure 1).
This trends to cause imbalance of magnetic field of transformer, reducing its rated working frequency from
20KHz to, say, maybe 15KHz (it varies according to different loads). This way, the frequency of noise falls
exactly into the range (200Hz-20KHz) that human ear can sense.
