Output Waveform: Pure Sine Wave. 2000W/ 6000W 12V to 240V PURE SINE WAVE POWER INVERTER CONVERTER LCD USB. The power inverter is with modified sine wave that's perfectly fine for resistive products, not work good for inductive products.
Excellent Inverter. Working perfectly and easy to replace the old broken one. 1500W perfect to run things & 3000W surge perfect for copeing with the microwave when it first starts & draws about 2000W for a second of surge, then drops to a constant 700W when cooking. Now I can park off grid, with no hook up electricity and use my TV; microwave or toaster etc and keep the fridge running in the background.. The pure sign wave allows running sensitive stuff like my laptop TV etc . All good.
