As the middle of the range this Inverter Charger is ideal for those who are running mid size items such as microwaves or kettles, and those who are running sensitive items such as flat screen TV's and computers 
  • 2500w Pure sine wave inverter
  • 70A (@ 12v) Battery charger
  • Battery charger will automatically detect and set for the battery bank size. There are 8 battery type options (e.g Gel, Wet lead acid etc) and de-sulphation capability
  • Dimensions: (mm) (w x h x l): 185 x 180 x  430 (1600 & 2500); 227 x 180 x 512 (3500)
  • Weight: 20kg (1500); 20kg (2500); 24kg (3500)
  • Status and Warning LED display is mounted on the main body of the unit
  • Remote panel (front control panel removable as remote, 10m remote cable)
  • Remote panel can be used to switch the unit On and Off

  • Basically the unit is a combined inverter (converts 12v DC to 240v AC) and battery charger (that converts 240v AC to 12v DC).
  • When plugged into the mains the unit will use the 240v power available to power the battery charger and hence charge the batteries. The unit also has a transfer switch / Relay so that when the mains is connected, rather than using the inverter the mains power can be switched straight through to your 240v system (hence you arent drawing on the batteries).
  • When NOT plugged into the mains the unit wont be able to charge the batteries (because it hasnt got an external power source to draw from) but will act as an inverter to power your 240v system.
  • A clever feature is that the unit has a crossover function so if you are running equipment on your 240v system and for whatever reason the mains input to the charger is cut, the inverter will switch on and continue to support your 240v usage quick enough that your equipment will be unaffected (less than 20 milliseconds)

A pure sine-wave AC output is exactly the same as comes out of the socket in your wall at home. A Quasi sine-wave is an approximation of a pure sine wave, instead of being a smooth wave it is a series of steps that approximate a smooth wave.

A Quasi sine wave inverter will run most generic equipment such as phone chargers, Hair dryers, Microwaves, Kettles, Fridges etc (obviously the inverter needs to be an appropriate size to run the desired piece of equipment). However, more technical equipment normally needs a Pure sine wave to run sensitive circuitry or motors, some specific examples are computers, washing machines and flat screen TV's (again the inverter needs to be appropriately sized to run the desired piece of equipment).
