Product Overview
LEYUE OPIM-3000 is a 3000W modified sine wave inverter that converts DC 12V/24V to AC 110V/220V, suitable for data centers, factories, off-grid solar systems, RVs, marine vessels, and outdoor work sites.
This model delivers 3000W continuous power and 6000W surge power, easily handling the inrush current of inductive loads such as motors and compressors. It adopts a CPU intelligent control scheme, effectively improving conversion efficiency and reducing electromagnetic interference. Overall efficiency reaches up to 90%, with no-load current as low as 0.2A (48V model), significantly reducing standby power consumption.
The unit is built with multiple protection functions: low voltage alarm and protection, over voltage protection, overload protection, over temperature protection, short circuit protection, and input reverse polarity protection (fuse). An intelligent temperature-controlled fan automatically adjusts its speed according to load and temperature, ensuring stable long‑term operation. The aluminum alloy housing provides excellent heat dissipation, with dimensions of 405×166×85mm and a net weight of 3340g.
OPIM-3000 is available in three DC input options (12V, 24V, 48V) and two AC output options (110V, 220V) to meet voltage requirements in different countries and regions. It is equipped with a 5V 1A USB port for direct charging of small devices such as mobile phones. Dual frequency output (50Hz/60Hz) is supported, making it compatible with global power grid standards.
LEYUE operates its own production facility with full quality control from component sourcing to final assembly, ensuring consistency and reliability of every unit.-
Modified sine wave inverters deliver reliable power for most equipment at a significantly lower cost than pure sine wave models, making them an ideal choice for high-power off-grid applications.
Nine layers of protection cover virtually all abnormal conditions, from low voltage and over voltage to overload, over temperature, and short circuit.
The intelligent temperature-controlled fan paired with the aluminum alloy housing effectively manages operating temperatures, extending component life and supporting continuous operation.
Dual frequency support (50Hz/60Hz) and multiple input/output voltage combinations ensure global compatibility—plug and play, no complex configuration required.
Off-Grid Solar Systems:
Primary AC source for lighting, resistive heaters, and kitchen appliances in remote cabins.
Mobile Workstations & RVs:
Powering high-draw hair dryers, microwave ovens, and power tools for construction sites.
Industrial Backup Power:
Reliable emergency source for non-sensitive factory machinery and ventilation fans.
Heavy Duty Power Tools:
Driving circular saws, drills, and high-torque equipment in remote field operations.
Q: Can the OPIM-3000 run sensitive medical equipment or high-end servers?
A: No. Modified sine wave inverters are ideal for resistive and many inductive loads; however, for sensitive electronics like medical monitors or complex server clusters, we recommend our OPIP Pure Sine Wave series to avoid interference.
Q: What size DC cables are required for a 3000W 12V setup?
A: At full 3000W load, current exceeds 250A. We strictly recommend using high-quality 2/0 AWG pure copper cables and keeping the length under 1.5 meters to prevent voltage drop.
Q: Is the 6000W peak power sustained?
A: No, peak power is designed for startup "surge" only (typically up to 3 seconds). The unit is rated for a continuous 3000W workload.
