Xantrex Technology HW 1000 manual Inverter Loads, Overload Conditions, High Surge Loads

Inverter Loads

The Freedom HW will operate most AC loads within its power rating of 1000 watts. However, some appliances and equipment may be difficult to operate, and other appliances may actually be damaged if you try to operate them with the Freedom HW. Please read “High Surge Loads” and “Trouble Loads” carefully.

Overload Conditions

	There are two kinds of overload conditions:
	• An overload warning and
	• An overload shutdown.
Overload	When the Freedom HW’s AC load is approximately 100 W below the
Warning	overload shutdown limit of ~1000 W, the audible alarm beeps once every
	two seconds and the display screen shows a fault code E06.
Overload	When the Freedom HW’s AC load increases to near ~1100 W, the audible
Shutdown	alarm beeps every second and the display screen shows a fault code E03.
	The Status LED turns solid RED and in 30 seconds, both the unit and the
	display screen will shut down to prevent damage to the inverter and
	protect the battery from being over-discharged.

High Surge Loads

Some induction motors used in freezers, pumps, and other motor-operated equipment require high surge currents to start. The Freedom HW may not be able to start some of these motors even though their rated steady state current draw is within the inverter’s limits. The unit will shut down and indicate an overload shutdown.

A single incandescent bulb requires five to ten times its power rating when lighting up from a cold start. If you have several bulbs lighting up all at the same time, then the surge is even greater.

A Compact Flourescent Light or CFL also has a momentary surge that is more than ten times its power rating when lighting up from a cold start.
