Import 5000w Modified Sine Wave Power Inverter — Buy in wholesale FOB from Supplier in China

The PQ-5000M is a 5000W modified sine wave power inverter that converts DC battery power to AC electricity, positioned for off-grid solar, vehicle, and backup power installations. Rated power is 5000W continuous with 10000W surge capacity, outputting 110V or 230V at 50/60Hz plus or minus 3Hz. Input voltage options are 12V or 24V DC, with replaceable fuse protection (40A for 12V, 20A for 24V). No-load current draw is 0.3A or below. The unit measures 528mm by 252mm by 101mm and weighs 8.5kg. A 5V 2.1A USB port is integrated. Protection functions include battery low voltage alarm and shutdown, over temperature, over voltage, short circuit, reverse polarity, earth leakage, and overload. The cooling fan operates under CPU-controlled load management rather than running continuously.

The modified sine wave output is achieved through SMD (surface-mount device) assembly, which reduces unit weight and size compared to through-hole construction. The aluminum heat sink and copper windings listed in the materials confirm a thermally conventional design. Modified sine wave inverters are less expensive than pure sine wave equivalents but may produce audible noise in inductive loads and reduced efficiency in capacitive or motor-driven equipment. The 10000W surge rating for 5000W continuous is a 2:1 ratio, standard for this product tier, supporting motor starting currents. The CPU-controlled fan extends bearing life and reduces acoustic output at partial load, a feature that distinguishes this unit from basic thermostatically-fanned competitors. Dimension and weight data suggest a fixed-installation unit rather than a portable inverter.

Target buyers include solar integrators, commercial vehicle outfitters, telecom infrastructure contractors, and industrial control system distributors. The 2-units-per-carton packaging and 8.5kg single-unit weight suit palletised sea freight for volume orders. Response rate data is not available, so direct negotiation is required to confirm MOQ, lead time, whether OEM branding is offered, and which certifications (CE, RoHS, ISO) are held. Buyers should clarify whether output voltage and frequency are factory-set or switch-selectable, as this affects inventory management for multi-market distribution. The application brief mentions renewable energy and portable power sectors, but the physical specifications lean toward fixed installations.

Zhejiang Pingqi Electric Co., Ltd. is based in China, postal code 632500, in a region with established electrical manufacturing infrastructure. The supplier's trust tier is listed as harbor. The response rate shows 0.00 percent with zero recorded average response hours, indicating no platform-mediated inquiry history is available. Buyers should therefore initiate contact through multiple channels and evaluate response speed and completeness as a primary supplier qualification step. The address confirms a Chinese registration/SKD location, though the broad address format suggests the listing may not display a detailed factory address, which is common for trading companies or manufacturers with multiple sites.

The source description frames the company as serving importers and distributors in renewable energy and portable power sectors, but no specific client names, revenue figures, employee counts, or factory floor area are stated. The product materials listed (PCB circuit board, copper windings, aluminum heat sink) describe generic inverter construction and do not confirm in-house manufacturing versus assembly. Buyers should request a factory audit or video verification, business licence with scope of business, and evidence of production capability such as photos of winding stations, test racks, and老化 (aging) test areas. The modified sine wave inverter market in China includes both dedicated manufacturers and trading houses, so clarifying actual production role is essential for warranty reliability and technical support continuity.
