SECTION 6 – MAINTENANCE AND TROUBLE SHOOTING
MONTHLY MAINTENANCE
At the minimum, check the level of the electrolyte in each battery cell once a month after the batteries
have been charged, not before. It should be about ½-inch above the top of the plates, but not
completely full. Most batteries have a plastic cup, which the electrolyte should just touch when full.
Don’t overfill the batteries or the electrolyte will spill out of the batteries during charging. Only refill
the batteries with distilled water – spring water and regular tap water may have a high mineral
levels which can poison the battery chemistry and reduce battery life.
Check the battery interconnections for tightness and corrosion. If any corrosion is found, disconnect
the cables and carefully clean with a mild solution of baking soda and water. DO NOT ALLOW THE
SOLUTION TO ENTER THE BATTERY. Rinse the top of the battery with clean water when finished.
To reduce the amount of corrosion on the battery terminals, coat them with a thin layer of petroleum
jelly or anti-corrosion grease available from automotive parts stores or battery suppliers. Do not
apply any material between the terminal and the cable lugs – the connection should be metal to
metal. Apply the protective material after
the screws have been tightened.
TROUBLE SHOOTING GUIDE
TROUBLE INDICATION POSSIBLE CAUSE POSSIBLE SOLUTION
BATTERY HI - RED (LED) is on and
a buzzer is heard
.
Battery voltage is above the high
battery voltage input tolerance.
Check for the correct battery voltage
at the inverter’s DC input terminals.
Ensure the DC source is regulated
below the High battery cutout voltage.
BATTERY LOW – GREEN (LED) is
on and a buzzer is heard
.
Battery OVER-DISCHARGE
PROTECTION circuit is on.
Battery voltage is below the low
battery voltage input tolerance.
Charge battery or disable the OVER-
DISCHARGE PROTECTION setting
(turn adjustment to OFF).
Check for the correct battery voltage
at the inverter’s DC input terminals.
Check for an external DC load on the
batteries. Check condition of
batteries and recharge if possible.
Check AC INPUT circuit breaker on
the side of the inverter.
OVERTEMP – RED (LED) is on and
a buzzer is heard.
AC input voltage may be too high.
Operating too large of a load.
Ambient temperature may be high or
inverter-cooling fan may have failed
or the airflow thru the inverter is
blocked.
Check for high AC voltage, turn
charge rate down.
Remove excessive loads.
Let inverter cool down before
restarting and check inverter-cooling
fans, or check for anything preventing
airflow.
