E.7.1 The Inverter

The Inverter section of the unit produces a high quality Sinewave output, the quality of this output is compatible with any appliance, Thanks to the generous dimensioning of the unit , you can operate appliances requiring higher power than the nominal power of the unit for a short time. The unit provide up to 3-times the nominal power to start motors etc.

E.7.2 Power saving function (Fn02)

In order to avoid unnecessary discharge of the battery, the inverter switches OFF automatically if no AC power is being used. The unit switches ON automatically again if an AC load is switched ON. The AC Out LED blinks if the inverter is in “Power Saving-Mode”.

If the “Power Saving-Mode” is not wanted, set the Fn02 "DISABLE" function. This will keep the unit running continuously, but will also discharge your batteries quicker.

E.7.3 Overload

If the unit is overloaded for too long or too heavily, it switches off. The

“Multi-display” will show “” and the “RUN/STOP” LED will RED Blink. After approximately 10 seconds the Inverter switches on automatically. If the unit is overloaded four times in quick succession, then it no longer switches back on

automatically. The “RUN/STOP” LED remains lit, and the multi-display show “”. Press the push button 1(PB1) ”RUN/STOP” in order to switch the unit back ON.

E.7.4 Overheating (Over Temp)

If the Inverter has been overload for a long time or it has been working in a high

ambient temperature, it will switch OFF. The “Multi-display” will show “” and the “RUN/STOP”LED RED blinks. After cooling down, the inverter switches back on automatically. One minute before the inverter switches off due to high temperature a buzzer will be heard. If the Auxiliary Contact has been programmed for “Over Temp” then the contact will be active when the buzzer sounds. This could be used for example to start an emergency back up generator, creating a no break energy supply.
