## Summary description

SINUS PLUS 4000 is a voltage converter that transforms 24 V DC to 230 V AC with continuous output 2000 W and peak power 4000 W. Designed for powering household appliances and electronic devices where a stable AC supply is needed from a 24 V battery source. Suitable for mobile, off-grid and backup applications; provides surge capacity for motor starts and temporary high loads.

## Long description

The SINUS PLUS 4000 24/230V 2000W/4000W is a pure sine wave voltage converter that converts 24 V DC to 230 V AC with a continuous output of 2000 W and a peak (surge) capacity of 4000 W. It is intended to provide a stable alternating current supply from a 24 V battery source for household appliances and sensitive electronic equipment. The inverter features pure sine wave output to ensure compatibility with motors, compressors and electronic power supplies, and is suitable for mobile, off-grid and backup power applications where short-term high starting currents may occur.
Advantages
The device delivers a clean pure sine output that reduces interference and risk of damage to sensitive electronics compared with modified sine inverters. With 2000 W continuous power and 4000 W surge capability it supports appliances with high inrush currents such as refrigerators, power tools and pumps. Designed for 24 V systems, the converter offers reliable voltage stabilization and automatic protection functions to guard against overload, overtemperature and low battery voltage. Its build balances power density and portability for installation in vehicles, boats or stationary backup setups.
Suitable for
Powering household appliances from a 24 V battery system (fridge, microwave, TV)
Running power tools and compressors with high start-up currents
Providing backup power for essential electronics during outages
Mobile and off-grid installations in vans, RVs, boats and cabins
Key specifications
Input voltage: 24 V DC
Output voltage: 230 V AC (pure sine wave)
Continuous output power: 2000 W
Peak (surge) power: 4000 W
Output frequency: 50 Hz
Protection features: overload protection, thermal protection, low battery shutoff
Intended use: powering resistive and inductive loads including motors and electronic devices
How to use
Install the inverter in a well-ventilated, dry location near the 24 V battery bank and secure it to a stable surface. Connect the positive and negative DC terminals to the battery using appropriately sized cables and fuses to match the expected current. Connect the 230 V AC output to the appliance or distribution panel, observing local electrical codes. Start the inverter and monitor input voltage and load; the unit will supply continuous power up to its rated 2000 W and handle short-term surge loads up to 4000 W. If protection indicators activate, reduce the load and check battery condition, wiring and ventilation.
Usage recommendations
Use properly rated battery capacity and cabling to avoid excessive voltage drop and to ensure safe operation under high loads. Allow sufficient ventilation space around the inverter to prevent overheating, and install a suitably rated DC fuse or circuit breaker close to the battery positive terminal for protection. For appliances with continuous high power draw, verify that the combined run-time and battery capacity are matched to avoid deep discharge. Follow local wiring regulations and consult a qualified electrician for fixed installations.
