Xantrex Technology 1800, 1000i Testing, Inverter Operating Limits and Protection Features

approximately three seconds, and then turn the switch back to (I) position. “POWERSAVE ON” will now be displayed during the start-up sequence and when the normal state display appears, a small pointer will be visible, indicating POWERSAVE mode is enabled. Repeat the same procedure for disabling POWERSAVE mode.

3.5Inverter Operating Limits and Protection Features

Power Output: The Prosine 1000 Inverter will continuously deliver 1000 watts and the Prosine 1800 delivers 1800 watts continuously. The following table displays the continuous and peak current ratings as well as surge rating, depending on the model:

	Continuous AC	Peak AC		Surge Rating
				(max. watts
	Output Current	Output Current
				delivered for 5
Model	Rating	Rating		seconds)
1000	8.3 A	25	A	1500
1800	15 A	45 A		2900
1000i	4.3 A	11	A	1500
1800i	7.8 A	20	A	2900

Each unit above will be able to operate all AC loads rated at or below these power ratings. Some high- horsepower induction motors used in pumps and other motor-operated equipment require very high surge currents to start and the Prosine Inverter/battery combination may have difficulty starting these loads. If you have problems with certain loads, ensure that battery connections are solid, your DC cables are appropriately sized, and that the battery is of sufficient capacity and fully charged.

Input Voltage: The Prosine Inverter operates from an input voltage ranging from:

10 to 16 VDC for 12 V models

20 to 32 VDC for 24 V models

Peak performance for these inverters occurs when DC input voltage is in the range of 12 volts to 15 volts for 12 V models and 24 volts to 30 volts for 24 V models. The Prosine Inverter will indicate high and low DC voltage conditions as follows:

	DC Input	DC Input	DC Input	DC Input
	over	over	under	under
	voltage	voltage	voltage	voltage
Model	alarm	shut down	alarm	shut down
12 V	15.8 VDC	16.0 VDC	10.5 VDC	10.0 VDC
models
24 V	31.6 VDC	32.0 VDC	21.0 VDC	20.0 VDC
models

The over-voltage protection and shutdown protects the inverter against excessive input voltage, should the unit be connected to a higher voltage than it is designed for (up to 35VDC—higher voltages may cause damage). Low input voltage shutdown protects your battery from being over-discharged. The inverter requires a manual reset to re-start after shutdown from either high or low

input voltage. Turn the power switch to (#) and then back to (I) to re-start the unit.

Output Overload Protection: A short circuit may be applied to the output continuously without damage to any internal components. The Prosine Inverter will shut down in less than five seconds when the output falls 10% below the nominal voltage as a result of current limiting.

AC Backfeed Protection: Although the Prosine Inverter has been designed to withstand incoming AC at the AC output, this is only a safeguard and continuous AC backfeed could lead to inverter damage. Avoid inverter damage by double checking the AC input and output wiring on hardwire configured models before applying power and by understanding your source of AC and where power from the source leads to (e.g. do not plug a live extension cord into the AC outlet of the inverter).

Input Reverse Polarity Protection: The internal circuitry of the Prosine Inverter is protected by an internal, 32 V, fast-blow fuse as follows:

Model	Mfg & Model
1000 - 24 V	Littelfuse/Gould CNN80 or
1000i - 24 V	Bussmann ANN80 rated 80 A
1800 - 12 V	Littelfuse Mega 225 A
1800i - 12 V
All others	Littelfuse Mega 125 A

This fuse is only replaceable by qualified service personnel. In many reverse polarity conditions, this fuse will protect internal circuits, however, certain high voltage/current situations may cause internal damage.

4. Testing

The following simple test procedure should ensure that the inverter is connected and installed properly.

To test the Prosine Inverter:

1.Double check all wiring terminals on the inverter to observe correct polarity and secure connections.

2.Turn rocker switch to (I) position.

3.Observe the power-up sequence on the display. The normal-state inverter display of input current and input voltage should come up.

4.Plug a test load (e.g. a light bulb) into the outlet of the Prosine Inverter. The load should function normally. Observe the output power bar graph—it should increase with load demand.

5.For hardwire and transfer relay-equipped versions, plug a load into the AC output leg of the inverter while input AC is available. Remove input AC. The load should still operate normally. Replace the source AC input power and again, the load should operate normally, indicating proper installation and function of the transfer relay.

6.Repeat test 4 or 5 with the inverter in “POWERSAVE” mode.

7.The Prosine Inverter is now ready for operation.
