Other Warning Alarm Scenarios:
The most common cause of inverter error is that of low battery
voltage, this is due that as the inverters load increases, the battery
voltage decreases. As the battery capacity gradually decreases,
the voltage present at the inverter also decreases. To warn you of
an impending flat battery, the inverter sounds an alarm once the
battery voltage reaches a point of 10.7vdc. Should you choose to
ignore this alarm, the inverter will continue to operate until a final
shutdown voltage of 10.0vdc is reached. At this point in time, the
green PWR light will still be illuminated, but the FAULT light will
also be illuminated. Should a low battery event occur, you should
immediately recharge your battery to avoid the risk of premature
battery failure.
Other Causes of Low Battery Shutdown
Low battery shutdown need not always be as a result of a discharged
battery. Other common causes you should check are:
• Under sized battery cables, or excessively long runs from battery to
inverter.
• Loose terminal connections on either battery or back of inverter (be
sure at all times that the DC terminals on the inverter are tight).
• Starting events on the main battery (these can be common when
you start your engine as this draws the battery voltage down low for
a moment).
Other fault conditions
The red FAULT led may illuminate under the following causes:
• High DC battery voltage as a result of a defective battery charging
system.
• High internal heat (common if the cooling fans and vents are
blocked)
• Running devices well in excess of the inverters rated capacity.
The ePOWER inverter is designed to simply reset and restart once the
fault condition is removed. Should you continue to have a FAULT led
show during operation, please contact Enerdrive.
