Xantrex Freedom XC 2000 Watt True Sinewave Inverter, 80Amp Charger Model: 817-2080 Extended Surge Rating: Surges to 2X continuous power for 2 seconds for motor loads True Sine Wave AC Power: For operation of sensitive and motor loads Ignition Control: Feature to turn inverter on/off via a 12 VDC signal and to minimize battery drain by switching the inverter off when the ignition key is turned off Wide 10-18 VDC Input Range: Ensures inverter operation on high voltage alternators found on many new vehicle chassis Built-in 30A AC Transfer Relay: Senses when outside AC Power is present and transfers the load from the inverter to the source of incoming power (shore or generator). The unit also automatically switches from invert mode to charge mode Quick Installation: Huge wiring bay for easy access and quick connect AC in/out terminals for fast & easy wiring Power Factor Corrected Multi-Stage Charging: Utilizes less shorepower when charging batteries. This frees up more usable AC power for running electrical devices and appliances and reduces the likelihood of tripping shorepower breakers Programmable: Configurable 3 stage temperature compensated battery charge algorithm for optimal charging of almost any battery type up to 18V Battery Equalization: Maximizes flooded battery life Dead Battery Charging Down to 0 Vdc Power Share: Prioritizes AC loads by reducing the charge current and maintaining the total input current to less than the breaker setting The Freedom XC inverter/charger offers premium performance in a lightweight compact package. It cranks out full output in invert or charge mode from -4°F - 104°F for operation in all climate temperatures. The extended surge rating of the Freedom XC makes it ideal to start difficult loads including fridge and microwave. The quick connect terminals at AC IN/OUT make installation a breeze.
