AC Indicator 

LED

The AC Indicator LED indicates that AC power is available at all outputs. 

If AC power is available, this LED will illuminate whether or not the 

PowerHub 1800 inverter is turned on or not.

Operating Mode LEDs

Bypass LED

When AC power source is available, the PowerHub 1800 will pass the 

power through to the loads and will also keep the battery bank charged 

and usable. The Bypass LED will illuminate when the unit is in this mode.

On initial power up or if transferring from Inverter Mode back to Bypass 

Mode, the PowerHub takes approximately 20 seconds to identify if an AC 

source is available and stable. If the AC source is within the acceptable 

voltage range, the PowerHub will automatically enter Bypass Mode. 

During this time, the Bypass Mode LED will flash and power will still be 

provided by the inverter. When the AC source has been qualified, the 

Bypass Mode LED will stop flashing and illuminates solid and the loads 

will be powered by the AC source.

Inverter LED

If the ON/OFF Power Button has been pressed to turn on the inverter, 

when the AC source fails, the PowerHub 1800 automatically switches to 

Inverter Mode within 40 milliseconds. When in Inverter mode, the 

inverter is using the power stored in the battery bank to provide power to 

the loads and the Inverter LED will illuminate.

Status LEDs

Input LEDs

Select Button 

(Red)

Pressing the red Select Button cycles the output on the display through the 

available Input/Output power levels. 

If the Select button is not pushed within 10 seconds, the display will 

automatically return to the Net Power value.

Wind LED

When the Select Button is pressed until the Wind LED is illuminated, the 

Wind Input wattage levels are displayed in kilowatts. These values are the 

inputs on the 80 A DC input terminals.

WARNING: Shock Hazard

The ON/OFF Button controls the output of the inverter only. It does not control 

or turn off the AC output in Bypass Mode. Therefore, if any power is available to 

the unit, the unit will function in Bypass Mode and power will be available at all 

outlet or output terminals even if the PowerHub is turned OFF. The blue AC 

Indicator LED between the top two AC outlets on the front panel will illuminate 

if power is available at any of the outlets or output terminals.
