The Komunica A-301/4000-24-REMOT is a high-power inverter designed to convert power from a 24V DC battery or installation into 220V AC output, allowing compatible equipment to be powered where mains electricity is not directly available.

With listed continuous output power of 4000W and peak output power of 8000W, it is suitable for demanding applications where AC power is required from 24V batteries, provided the equipment consumption and electrical installation are correctly sized.

This model uses a modified sine wave output, also commonly described as rectified wave, and is intended for loads compatible with this type of inverter. For sensitive equipment, motors, devices with complex electronics, power-factor-corrected power supplies or medical equipment, compatibility should be confirmed before use.

The listed input range is 20 to 30V DC, with low battery alarm at 21.5V ±0.8V DC and low voltage shutdown at 20V ±0.8V DC, helping protect the battery from excessive discharge.

The inverter includes multiple protections, such as soft-start, low and high input voltage protection, overload protection, overtemperature protection, output short-circuit protection, fuse-based polarity protection and intelligent fan control.

The wireless remote control allows easier switching or control of the inverter, especially in installations where the unit is mounted in a less accessible place, such as vehicles, mobile installations, auxiliary power systems, workshops or backup power applications.

Important note

Before installation, always confirm the real power consumption of the equipment, load type, modified sine wave compatibility, battery capacity, cable cross-section, protective fuses, ventilation, polarity, distance between battery and inverter and electrical safety of the installation.

A 4000W inverter on 24V can require very high current. The specification lists 200A full-load input current, so installation must use suitable cables, firm connections, correct protection and a compatible battery or battery bank.

As this is a modified sine wave inverter, compatibility with all appliances should not be assumed. Sensitive equipment, motors, refrigerators, pumps, specific chargers, UPS systems, medical equipment or devices with complex electronics should be tested or confirmed beforehand.

This item corresponds to the Komunica A-301/4000-24-REMOT 4000W 24V/220V inverter with remote control. Battery cables, terminals, external fuses, batteries, chargers, solar panels and other accessories are not included unless expressly stated otherwise.
