Sterling 3000W Sine Wave Inverter + UPS

We stock a range of sterling sine wave inverters from smaller models of 150/300w up to the more specialised 3Kw variants.

The new Sterling pure sine wave, heavy-duty inverter ensures all electrical products run at their very best.

It removes all problems linked with quasi sine inverters such as small black lines on some TV screens. Works satellite controllers, runs microwaves at 100% power, works thyristor controlled devices.

Sterling sine wave inverters remove problems caused by low cost, non isolated sine wave inverters, such as interference on TV screens, radio and hi-fi noise, and works all CD and DVD players. This unit runs all equipment as per the main -guaranteed.

The 2500 watt unit will also run a standard washing machine and all thyristor controlled devices which cannot be run by quasi sine .

All Sterling sine wave inverters come with a stand by circuit which offers a 0.2 amp consumption with no load, and a low on line loss of about 1.2 amps.

Sterling pure sine wave inverters are suitable for all uses, the sosphisticated technology used prevents the problem that sometimes occur with the use of the cheaper modified / quasi sine wave inverters.
