The Voltage converter SINUS PLUS 4000 12/230V pure sine inverter 2000W continuous 4000W peak converts 12V DC battery power into stable 230V AC with a pure sine waveform. Designed for applications where a reliable mains-like output is required, this inverter supplies continuous power up to 2000 W and can deliver short-term peak power up to 4000 W to handle motor starts and other surge loads. The unit is intended for use in vehicles, boats, off-grid cabins, and mobile or temporary installations where AC equipment must run from a 12V source.
Advantages
The pure sine output produces a clean, low-distortion AC waveform that is compatible with sensitive electronics, audio equipment and modern appliances. High peak capability allows the inverter to start inductive loads such as pumps, compressors and power tools without nuisance shutdowns. Built-in protections and a compact design offer practical deployment and safer operation in confined spaces.
Suitable for
- Powering household appliances like refrigerators, microwaves and kettles (within continuous power limits)
- Operating power tools and workshop equipment that require high startup current
- Running computers, routers, audio systems and other sensitive electronics
- Use in vehicles, boats, caravans and off-grid solar or battery systems
When it may not be suitable
This inverter is not suitable for continuous loads that exceed its 2000 W continuous rating; attempting to run larger loads for extended periods may cause overheating or protective shutdowns. It is also not intended as a replacement for a full mains distribution system in permanent commercial installations where three-phase power or higher continuous ratings are required.

How to use
Connect the inverter to a 12 V battery or battery bank using appropriately sized cables and secure terminals, observing correct polarity. Place the inverter in a well-ventilated location with clearance for airflow and connect AC loads to the 230 V outlets. Turn the unit on and monitor the load to ensure it stays within the continuous rating. Use the included remote control if available to switch the inverter on/off from a distance. Follow the manufacturer’s installation recommendations and safety instructions when wiring and mounting the device.
What to consider before purchase
- Match the inverter continuous and peak ratings to the expected loads, accounting for high startup currents of motors and compressors.
- Ensure the battery capacity and battery type can supply the required power and run time without excessive voltage drop.
- Verify available installation space and ventilation to prevent overheating during sustained use.
- Confirm presence of necessary safety protections and appropriate cable sizes for input connections.
Usage recommendations
For reliable operation, use heavy-gauge battery cables, install a suitable fuse close to the battery, keep average loads below the continuous rating, and allow for adequate ventilation. When powering inductive or motor-driven appliances, expect the initial peak draw and ensure the battery and connections can support that surge. Regularly check connections and battery condition to maintain stable 230V output.
