Use:
• Make sure to not connect appliance that demand pure sine wave as this
inverter provide a modied sine wave.
• Check so the connected appliances don’t exceed the inverters total power.
• Make sure the battery is fully charged.
• Allow free space around the ventilation holes/cooling fan.
1. Make sure the connected appliance is switched off before connecting to
the mains socket on inverter.
2. Turn the on/off switch into position ”I”. Always turn on the inverter before
turning on the connected appliance.
3. Green diode light up when the inverter is working normally. The cooling
fan is temperature operated and start only when needed. Can therefore
be in off position if small load is connected.
Note:
• Never use longer leads than needed between inverter and connected appliance. Long cables can lead to unwanted voltage drop and bad function.
• Switch off the inverter when it’s not in use.
Remote on/off function with Remote 1 (accessory):
To all models it’s possible to connect and use a ”Remote 1” panel. It’s
equipped with 6m cable and an on/off (I - 0) switch. Fits together with WHS300/600/1000 and 1700 models. This remote supports easy on/off operation
if the inverter is placed in a difcult to reach position.
Using a modify sine wave inverter together with a
motor or a pump:
It’s important to use an inverter that provides an output power proportional to
what is connected. A motor or pump requires a great deal of initial power when
starting up. This can be up to 3-4 times it’s current under normal operation.
In order to support this an inverter with double or even four double power is
needed.
When using a modied sine wave inverter to motor/pump applications noise
can be generated. This is caused by the modied waveform coming from the
inverter. It’s therefore preferred to use a inverter with pure sine wave output in
order to get a normal and silent running application.
If you have no choice, you can use an inverter with modied sine wave.
Measuring the output voltage:
The inverter produces a modied sine wave output AC voltage (square wave).
This require a volt meter that can measure ”TRUE RMS”. If the output voltage
is measured with other type of meter the voltage shown might be 20-30 V
less than the actual voltage.
Troubleshooting:
• Switch off the inverter if any problem.
• Disconnect all appliance connected to the inverter.
• Check carefully connections and appliance used with the inverter.
Low or no output voltage:
• Bad connection can give low or no output voltage. If so, check all connections between inverter and appliance carefully.
• Measure the output voltage from mains socket with a ”TRUE RMS” meter.
• Check the fuse (valid only for the 300W model). For all other models the
fuse is placed inside the inverter and must be replaced by an qualied
electrician.
The red diode illuminates:
• The battery voltage is too low – charge the battery.
• The inverter is overloaded – reduce the load.
• The inverter has been overheated – move the inverter to a cooler place
and check the ventilation holes are not blocked.
• The inverter is defect – contact the supplier’s technical support.
