Xantrex Technology PH1800 manual Basic Functions of the PowerHub, Primary AC source

Introduction

Basic Functions of the PowerHub 1800

Bypass	When AC power is available from a generator or utility grid, the
Function	PowerHub will function as an automatic backup power unit. It will sit in
	Bypass mode and will pass the power through to support the loads and/or
	the battery charger. When the AC input fails, the PowerHub’s Automatic
	Transfer Relay de-energizes and will switch the unit to Inverter Mode
	within 40 milliseconds.
	Once AC input is restored, after a 20-second delay the relay energizes and
	qualifies the AC input and the load is automatically reconnected to the
	primary AC source.

	WARNING: Shock Hazard
	If any AC power is available to the PowerHub 1800, the unit will pass through
	that power to any loads connected to it whether the unit is turned ON or OFF.
	Power will be available at the four outlets on the front of the unit as well as at any
	outlets hardwired to the unit through the AC distribution panel. There is a blue
	LED above the 15 A supplemental protector on the front of the inverter panel that
	will illuminate if AC power is available at the AC outlets.
	To completely disable this feature, the PowerHub must be completely
	disconnected from all input sources. Turning off the display will not eliminate
	this risk.
Inverter	When no AC power is available from a generator or utility grid, the
Function	inverter draws power from the battery bank and delivers a modified-sine
	wave AC output voltage. This output voltage can be accessed by using the
	four outlets on the front of the unit or by hardwiring the unit to the AC
	Distribution Panel which provides AC power to AC outlets at the site.
Charger	The PowerHub 1800 uses any single source of AC power such as a
Function	generator or utility grid to keep the batteries charged and ready for use.
	The PowerHub 1800 can also use renewable energy sources to keep the
	batteries charged.
	Important: Additional hardware, such as charge controllers, may be required
	for installations using renewable energy sources. Installations using renewable
	energy input must be hardwired into the installation for code-compliance.
Operational	As long as the battery voltage is between 11.0 Vdc to 15.0 Vdc, the
Voltage Range	inverter will continue to deliver AC power to the loads connected to it.
	When the battery voltage falls below 11.0 Vdc or rises above 15.0 Vdc,
	the PowerHub 1800 High or Low Battery Protection will engage and shut
	the inverter off, stopping all output voltage to the loads.
