Model:

SW150-12, SW650-24

SW350-12, SW1200-24

SW650-12, SW1800-24

SW1200-12, SW3000-24

Symptom

Possible Cause

Solution

AC output will not stay ON

Some loads may be to small to hold 

inverter ON

Increase size of load

Inverter shuts down due over 

temperature

Insufficient ventilation around inverter

Ensure true power rating of appliance 

(including power factor) is less than 

inverter output rating

Improve ventilation

Check ratings and reduce with dif-

ferent appliance

Inverter shuts down when trying 

to start a load

Possible surge from motor starting 

causing shut down

Check that battery voltage is within 

specification. If voltage drops ex

-

cessively when starting, batteries 

size may have to be increased. Or 

load is too large for inverter

.

Load LED flashes

Overload

Reduce load. Remove load.

Under V

oltage LED flashes

Low input voltage

Check battery status.     Re-charge 

if required.

Over T

emp LED flashes

Thermal shutdown

Improve ventilation.

Over V

oltage LED flashes

Excessive input voltage

Check input voltage. Reduce if too 

high.

TV channel interference on 

some channels

Connection of chassis ground lug at 

rear of inverter needs attention.

High power loads being used during 

TV viewing.

Ensure TV antenna providing a good 

signal.

TV is close to power inverter

.

DC power cables too long causing 

excessive radiated interference.

Check chassis ground lug is a 

solid connection.

Do not use high power loads.

Check antenna wiring and connec-

tion.

Move TV away from power in-

verter

.

Shorten cables if necessary and 

twist them together with approx. 2 

to 3 twists per foot.

Trouble Shooting:

WARNING! -

 Do not open or disassemble inverter

.

 Attempting to service the unit yourself may result in a risk of 

electrical shock or fire.

Safety Instructions:
WARNING! - 

Professional electrical / renewable energy installer should perform the installation, as dangerous 

voltages can be present. Before installing and using your inverte

r, read the Installation Instructions!

Explosive Gas Precautions:

This equipment contains components that can produce arcs or sparks. 

T

o prevent fire or explosion do not install in 

compartments containing batteries or flammable materials, or in locations that require ignition-protected equipment. 

This includes any space containing petrol-powered machinery, fuel tanks, joints or other connections between 

components of the fuel system.

Precautions When Working With Batteries:

• 

If battery acid contacts skin or clothing, wash immediately with soap and water

. If acid gets into eyes, immediately 

flood eyes with running cold water for at least 20 minutes and get medical attention immediately. 

NEVER

 smoke, 

allow a spark or flame in the vicinity of batteries or engine. Do not drop a metal tool on the battery as the resulting 
spark or short-circuit of the battery may cause an explosion.

 Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid 

battery

.

 A lead-acid battery produces a short-circuit current, high enough to weld a ring or similar metal, causing a 

severe burn.

WARNING! -  Shock Hazard! 

 Before proceeding further, ensure that the Inverter is NOT connected to any 

Batteries, and that all  wiring is disconnected from any electrical Sources. Do not connect the 0utput

 Terminals of 

the Inverter to an incoming 

AC sources.  

WARNING! - 

Reverse polarity connection will blow the internal fuse and may damage the inverter permanently

.

Before installing your inverter

, please make sure that you have appropriately sized batteries.

 A battery that is too 

small in capacity will not allow the inverter to perform to its full specification. 

The DC cabling must be connected to 

the correct polarity terminals of the battery bank. (Red = Positive, Black = Negative).

DO NOT

 extend the DC cable length to the inverter unless you are prepared to increase the diameter of the cable. If 

this is necessary consult your supplier or installer for advice.
