Description The Spartan Power SP-IC2224 2200 Watt 24V DC to AC power inverter/charger is a low frequency inverter that has a built-in 50A charger, 30A transfer switch and comes with a two year warranty. The SP-IC2224 is great for use at home or in RV, Marine, Fleet Truck, Emergency and many other renewable energy application environments. The SP-IC2224 is packed with unique features and is one of the most advanced inverter/chargers on the market today. The Spartan Power IC Series features power factor correction, sophisticated multi-stage charging and pure sine wave output with unprecedentedly high surge capability to meet demanding power needs of inductive loads without damaging your equipment. When utility AC power cuts off (or falls out of acceptable range), the transfer relay is de-energized and the load is automatically transferred to Inverter Mode. Once the qualified AC power is restored, the relay is re-energized and the load is automatically reconnected to AC Bypass Mode. Additionally, the inverter can also be easily customized to Battery Priority via a DIP switch. This helps to extract maximum power from the battery in renewable energy systems such as solar and wind.   Part Number: SP-IC2224   Features: 2200 watt low frequency inverter 6600 watt surge for 20 seconds 300% surge capability Load & Temperature controlled cooling fan Battery Priority Selector Terminal Block Marine Coated and Protected Remote panel available Auto frequency 10ms typical transfer time between battery and AC guarantees power continuity 18W power save mode 8 battery type settings for built-in charger Two Year Warranty   Inverter Output Specifications: Continuous Output Power: 2200 Watts Surge Rating: 6600 Watts (20 Seconds) Output Waveform: Pure Sine/Same as input (Bypass Mode) Output Voltage: 100-110-120Vac Nominal Efficiency: >88% (Peak) Line Mode Efficiency: >95% Output Frequency: 50Hz /- 0.3Hz / 60Hz /- 0.3Hz Typical Transfer Time: 10ms (Max) THD: min 5%   Input Specifications: Nominal Input Voltage: 24.0Vdc Minimum Start Voltage: 20.0Vdc Low Battery Alarm: 21Vdc-22.0Vdc Low battery Trip: 20.0Vdc-21.0Vdc High Voltage Alarm: 32.0Vdc High battery Voltage Restart: 31.0Vdc Power Save Mode Off: 32W Power Save Mode ON: 18W   Charger Specifications: Output voltage: Depends on battery Type Charger Rate: 50A Over Charge Protection Shutdown 31.4V Adjustable charge current: 0%-100% Four Stage Smart Charger   Transfer Switch Specifications: 30 amp automatic transfer switch 10 ms (max)   Dimensions: Unit Weight: 46.9 lbs.
