Operating in Invert Mode

Operating The Freedom SW 3000

IMPORTANT: Review the “Important Safety Instructions” on page iv before operating the inverter/charger.

Once the inverter/charger is installed, you can operate it in invert mode.

To operate in invert mode from the front panel:

1.Press the Inverter Enable button on the Freedom SW 3000.

2.If external AC is present, the External AC light illuminates. If AC is present and you want to operate the inverter, remove AC so the inverter turns on.

◆Once the Inverter On light is on, the Freedom SW 3000 inverter is ready to deliver AC power to the loads.

To operate the inverter with the System Control Panel, refer to “Operating the Freedom SW 3000 with the Optional System Control Panel (SCP)” on page 12.

IMPORTANT: If you are having problems with any of your loads, refer to “Inverter Applications” on page 54.

Operating Limits for Inverter Operation

Temperature The Freedom SW 3000 produces 120 volts AC at 3000 watts continuously in room temperature. The Freedom SW 3000 can deliver this power in an ambient (surrounding) temperature up to 77 °F (25 °C). In higher ambient temperatures, if the loads draw full power for an extended period of time, the unit may shut down to protect itself against overheating.

As with all inverters, the amount of continuous power that the Freedom SW 3000 can deliver without overheating is limited by the ambient air temperature. The Freedom SW 3000 will operate and deliver its continuous power rating at higher temperatures, but the ambient temperature as well as the input voltage from the battery will limit the extent to which the unit can run continuously.

The Freedom SW 3000 has 6000-watt surge for ten seconds. Operating the inverter/charger in conditions outside of power and temperature limits, however, will result in thermal shutdown and/or significantly decreased performance. In addition, operation in this range is outside the ratings covered by the regulatory approvals of the product. See “Invert Power Derating versus Ambient Temperature” on page 64.

Difficulty on starting loads The inverter/charger should be able to operate all AC loads rated at or below its power rating. Some high horsepower induction motors used in pumps and other motor-operated equipment require very high surge currents to start, and the inverter/charger may have difficulty starting these loads. See “Inverter Applications” on page 54.

If you have problems starting certain loads, ensure that:

•the battery connections are tight and clean,

•the DC cabling is no longer than the recommended length. Refer to the FSW3000 Sine Wave Inverter/Charger Installation Guide for this information,

•the AC wiring is of recommended size. Refer to the FSW3000 Sine Wave Inverter/Charger Installation Guide for this information, and

•the battery is of sufficient capacity and is fully charged.
