SINUS PLUS 4000 12/230V (2000/4000W) voltage inverter + REMOTE CONTROL 3SIR400012

Pure Sine Wave That Works Like a Home Socket

The inverter generates an alternating voltage with a sinusoidal waveform – identical to that in a household grid. This means it safely powers devices with motors, transformers, and sensitive electronics: refrigerators, air conditioners, compressors, washing machines, microwaves, or drills. You risk no equipment damage – there is no "modified sine wave" here, which can overheat or destroy circuits.

Remote Control and Intelligent Protection

You can turn the inverter on and off from anywhere thanks to the wired control panel – no need to reach the device itself. An LCD display on the housing shows the operating status. Built-in protections activate automatically: it shuts down in case of overload, overheating (above 60–70°C), low battery voltage (below 10.7 V), or short circuit. The temperature-sensor-controlled fan operates only when needed – quietly and efficiently.

For Those Who Want More Than Just an Inverter

It doesn't just power devices – you can integrate it with a photovoltaic system. The inverter is compatible with MPPT and PWM charge controllers – simply connect solar panels and utilize renewable energy directly to power loads. Additionally, it features one USB port (Type A), allowing quick charging of phones or tablets without the need for an extra adapter.

What Does This Mean in Practice?

• In a camper: You can run a refrigerator all night without worrying about battery depletion – the low-battery alarm warns in advance.
• On a construction site: Drills or grinders operate stably – no voltage "spikes".
• At home as a backup: When power fails – the inverter acts as a mini-UPS for TVs, computers, or central heating pumps.
• During installation: The aluminum housing dissipates heat more effectively than plastic – no need for additional ventilation.
• During charging: Low no-load current consumption (less than 1 A) – the battery does not drop below 10 V after several days of inactivity.

Input voltage: 10.5–15.5 V DC — operates even with a weak battery. Output: 225–235 V AC / 50 Hz — stable and compliant with Polish standards. Efficiency at full load: over 92%. Continuous power: 2000 W — sufficient for most household appliances and power tools. Peak power: 4000 W — handles motor startup without shutting down.
