output voltage.
Ensure that the electrical system in your vehicle can supply this unit without causing the
vehicle fusing to open. This can be determined by making sure that the fuse in the ve-
hicle, which protects the outlet, is rated higher than 360 Amperes for PST-300S-12E (12V
battery), or higher than 180 Amperes for PST-300S-24

opens repeatedly, do not keep on replacing it. The cause of the overload must be found.
On no account should fuses be patched up with tin foil or wire as this may cause serious

S Troubleshooting Guide
POSSIBLE CAUSE
There is no voltage at the
DC input terminals
Polarity of the DC input
voltage has been reversed
that has blown the exter-
nal / internal DC side fuses
(Note: Reverse polarity
may cause permanent
damage. Damage caused
due to reverse polarity is
not covered by warranty)
Low DC input voltage at
the inverter terminals and
the load is close to the
overload limit of 110%
(3300W).
DC input voltage is less
than 10.7V for 12V
versions and less than
21.4V for 24V versions.
Shut-down due to low
DC input voltage - Less
than 10V for 12V versions
and less than 20V for 24V
versions.
REMEDY
• Check the continuity of the battery
input circuit.
• Check that the internal/external battery
fuses are intact. Replace if blown.
• Check that all connections in the battery
input circuit are tight.
• Check external and internal fuses. Internal
E (24V battery). Information on t
fuses may be soldered and may not be easily
replaceable. Replace fuses. If unit does not
work, call Technical Support for repair.
• Check that the battery is fully charged.
Recharge, if low.
• Check that the battery cables are thick
enough to carry the required current over
the required length. Use thicker cables, if
required.
• Tighten connections of battery input circuit.
• Reduce load to below 3000W.
• Check that the battery is fully charged.
Recharge, if low.
• Check that the battery cables are thick
enough to carry the required current over
the required length. Use thicker cables, if
required.
• Tighten connections of the battery input
circuit.
• Check that the battery is fully charged.
Recharge, if low.
• Check that the battery cables are thick
enough to carry the required current over
the required length. Use thicker cables, if
required.
• Tighten connections of the battery input
circuit.
• The AC output voltage will switch ON au-
tomatically when the DC input voltage rises
to 11.5V ± 0.1V for 12V version and 23V ±
0.2V for 24V version.
