Basic System Architecture:

The following illustration shows the basic application for this inverter.It also includes the following devices to have a complete running system:

This inverter can power all kinds of appliances in-home or office environments, including motor-type appliances such as tube lights, fans, refrigerators, and air conditioners.

The Principle Diagram:

1.DC first mode:

When the solar energy is sufficient, it will charge the batteries and at the same time power the load in Pure Sinewave AC Output form(Fig 1).

When the Battery Bank has been discharged up to a certain level(default 48V) and the Grid is available, the system will switch to AC working mode(Bypass). If however, Grid is not available the Battery Bank will continue to discharge until the protection level(Fig 2).

When the battery voltage is recovered to the Recovery point(default 55V), the system will switch to Inverter mode automatically.

2.AC first mode(Fig 3):

Whenever AC input is normal, the system will run into AC working mode(Bypass), when AC input is abnormal, the system will work as Inverter mode.

3.SAVER mode(Fig 4):

Product Information:

The front panel

If the SAVER switch turns on, the system will work into SAVER mode, at the same time, the output will be shut, and the solar will charge the battery.

①AC indicator(GREEN=Grid Normal; OFF=Grid Abnormal)

② Solar indicator(GREEN=PV normal;OFF=PV abnormal)

③ Wind indicator(Only available in NKW series)

④ Battery indicator(GREEN=Battery Voltage Normal; RED=Battery Voltage Low)

⑤Inverter indicator(GREEN=System Working Normally; OFF=No Output)

⑥ Fault indicator(RED=System At Fault; OFF=No Fault)

⑦ Power on/off button(Long press 2 seconds or more to turn on, and long press 2 seconds

until the buzzer ring to shut down. If solar or Grid is normal this button will not work)

⑧ Setting button

⑨ Select button

⑩ Flip-screen button

NOTE: Having solar or mains input, the system will start automatically
