INVERTER MANUAL

MSW-2000/2500/3000/4000
Modified sine wave

Please read this manual carefully for optimal inverter usage.
Technical development is sometimes quicker than manuals can be printed so we apologise for any text, technical or illustration errors.

Introduction

The inverters are equipped with protection against wrong usage or connection.
If any of these situations will occur, an internal buzzer can sound, red diode light up or automatic shutdown of the inverter.

Short circuit protection: The inverter switches off until the short circuit has ceased.
Low input voltage: The internal buzzer sound at low input voltage and the red diode lights up. See ”technical data” for voltage limits. If the voltage drops below the limit, the inverter will automatically shutdown to protect the inverter and at same time avoid total battery discharge.
Over voltage protection: The red diode lights up and the inverter shutdown automatically if input voltage is too high. See ”technical data ” for voltage limits.
Overload protection: The red diode and lights up and the inverter shutdown in case of constant overload or high peak loads.
Thermal protection: The red diode lights up and inverter shut down automatically at temperatures higher than 60oC(±5oC)

Warning

The inverter should be used indoor and not be exposed to rain or moisture.
Never open the inverter yourself, repairs should be carried out by qualified personal using original spare parts to avoid personal and property damage.
Always disconnect the inverter from the battery before service or other adjustment.

Make sure to protect the inverter and the connections against children. Remember the output voltage is as dangerous as the voltage from a regular wall socket.
Never use damaged mains or battery cables and make sure to only use original replacement parts.
Make sure to connect the inverter with correct polarity. Wrong polarity connection can damage the inverter, which is not covered by the guarantee.
Don’t load the inverter when connecting or disconnecting it.

Connection

The inverter comes with cables that connect directly to the battery poles.

PLEASE NOTE! The battery cables supplied with the inverter must be used for warranty reasons. Longer cables or smaller cable area may damage the inverter.

Make sure the inverter on/off switch is in off position (0).
Connect red cable to positive (+) terminal on the inverter and to positive (+) pole to the battery.
Connect black cable to negative (-) terminal on the inverter and to negative (-) pole to the battery.
Make sure wires are tight connected to avoid sparking and voltage drops.

Use

Make sure to not connect appliance that demand pure sine wave as this inverter provide a modified 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.

Make sure the connected appliance is switched off before connecting to the mains socket on inverter.
Turn the on/off switch into position”I”.Always turn on the inverter before turning on the connected appliance.
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 2 (accessory)

To all models it’s possible to connect and use a Remote panel.
For MSW-1000/1500/2000/2500/3000/4000 it’s Remote 2with on/off switch and three function/warning Led. The remote panels are equipped with 6m cable and supports easilyon/offoperationiftheinverterisplacedinadifficulttoreachposition.

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 whatisconnected.Amotororpumprequiresagreatdealofinitialpowerwhen startingup.Thiscanbeupto3-4timesit’scurrentundernormaloperation. In order to support this inverter with double or even four times power is needed. When using a modified sine wave inverter to motor/pump applications noise can be generated. This is caused by the modified 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 modified sine wave.

Measuring the output voltage

The inverter produces a modified 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 ”TRUERMS” meter.
Check the fuse (valid only for the 300/600W model). For all other models the fuse is placed inside the inverter and must be replaced by a qualified 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.
