Hardkorr 3000W Pure Sine Wave Inverter
Hardkorr 3000W Pure Sine Wave Inverter
The flagship of Hardkorr's LS inverter range, the 3000W delivers reliable 240V power for serious off-grid setups - genuine pure sine wave output that protects sensitive electronics rather than the rough approximation a modified sine inverter produces.
Enough power to run real appliances simultaneously
At 3000W continuous output with a 6000W peak surge (0.2 seconds), this inverter handles multiple high-demand devices at once - hair dryers, air fryers, even caravan air conditioning - without compromise. Paired with around 300Ah of battery capacity capable of 300A continuous discharge, it delivers genuine off-grid freedom rather than a token backup supply.
Pure sine wave, properly engineered
With less than 5% total harmonic distortion and over 93% efficiency at 30% load, the output is clean enough for laptops, phones, and other sensitive electronics that can be damaged or simply run poorly on cheaper modified-sine alternatives.
Compact for its output
At 412mm x 190mm x 95mm and 4.1kg, the 3000W maximises space efficiency in caravans, motorhomes and expedition vehicles - serious capability without dominating your power bay.
