The Spartan Power SP-IC4448 4400 Watt 48V DC to AC power inverter/charger is a low frequency inverter that has a built-in 45A charger, 120V/240V capable and comes with a two year warranty. The split phase SP-IC4448 is capable of producing 2 legs of 110v and is packed with unique features making it 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.

For 4400 & 6600 watt models, there is one multiple controlled DC fan and one AC fan. The DC fan will work in the same way as the 2200-3300 watt models, while the AC fan will work once there is AC output from the inverter. When the inverter is in power saver mode, the AC fan will work from time to time in response to the pulse sent by the inverter in power saver mode.
