Voltage inverter SINUS 4000 24/230V (2000/4000W) 3SIP400024

Pure sine wave – power devices that other inverters cannot handle

This inverter produces a pure sine wave output – identical to household grid voltage. It’s not a crude square or trapezoidal wave, but a smooth, continuous sine waveform that doesn't damage sensitive components. That’s why it works reliably with refrigerators, air conditioners, central heating pumps, or washing machines – devices with induction motors and transformers that require clean power.

Works where you need it – and doesn’t shut off after a few seconds

With a continuous power rating of 2000W, it delivers stable power for multiple devices simultaneously – such as a TV, LED lights, and a charger. When you need a brief surge – for example, when starting a compressor or drill – the inverter handles impulses up to 4000W without tripping. There’s no “overload” shutdown after 5 seconds; protection only activates after sustained overload, giving enough time to start motors. It operates with input voltage ranging from 21V to 31V – meaning the battery can be partially discharged while the device still functions. The cooling fan activates automatically, and the unit operates reliably down to -10°C – ideal for cold conditions at campsites or in trucks.

Safe and reliable – no need to worry about your battery

It features seven protection mechanisms: short-circuit, overload, overheating, low voltage (shuts off at 21.4V to prevent deep battery discharge), high voltage, and even grid brown-out protection. Idle current is only 300mA – when nothing is connected, it won't drain your battery. Two 230V outlets allow you to plug in two devices at once – for example, an air conditioner and a lamp. There are no USB ports or UPS functionality – this is not a power bank or a “plug-and-forget” emergency source. It’s a tool for those who need strong, clean AC power without unnecessary extras.
