40.8±0.8VDC(48V version)
1.Check that the battery is fully
charged. Recharge, if low
2. Check that the battery cables
are thick enough to carry the
required
current
over
the
required length. Use thicker
cables, if required
3. Tighten connections of the
battery input circuit.

1. Check that the voltage at the
DC input terminals is more than
15V/30V/60V DC.
2. Ensure that the maximum
charging voltage of the battery
charger

V/30V/60VDC
3. Ensure that an un-regulated
solar panel or wind turbine is not
used to charge a battery

System overheating
1. Check that the fan is working.
If not, the fan / fan control circuit
may be defective
Call Technical
Support
2. If the fan is working, check
that the ventilation slots on the
suction side and the openings
on the discharge side of the fan
are not obstructed
3. If the fan is working and the
openings are not obstructed,
check
that
enough
cool
replacement air is available.
Also check that the ambient air
temperature is less than 45º C
4. Reduce the load to reduce the
heating effect
5. After the cause of overheating
is removed and the unit cools
down, it will reset automatically

The loads is 200% higher than
rated power.
1. Disconnect the load
2. Reduce the load
3.Cool the unit.
