Symptom Possible Cause Recommended Solution
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.
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 sometimes the transformer and/or case of the inverter may vibrate and make noise.
If the noise comes from transformer:
According to the characteristics of our inverter, there is one type of load which most likely may cause
rattles of transformer.
