About Guangzhou Nianguan Electronics Technology Co., Ltd. - DC, AC Inverters & Converters Supplier in China

China, Guangzhou, hosts Guangzhou Nianguan Electronics Technology Co., Ltd., which currently lists 17 active products on its catalogue. The company’s catalogue is split between DC/AC inverters and converters and solar panel solutions. Products include a 500 W DC‑to‑AC inverter with built‑in charger, a 80 W‑5 kW power inverter series, 110 V‑220 V voltage converters, 22 V‑60 V grid‑tie solar inverters, micro‑inverters, 2.2 kW solar water‑pump systems, various pure sine‑wave inverters up to 2 kW, UPS units with charger functions, and waterproof grid‑tie units. One entry, the “Voltage converter 110v‑220v”, is recorded under HS code 8504.40 and specifies electrolytic copper windings, grain‑oriented silicon steel core, and galvanized steel housing. The remaining items are listed without HS codes in the supplied data.

The product titles use generic industry terminology such as “pure sine wave”, “grid‑tie”, “micro‑inverter”, and “solar charge controller”. The solar panel entry is listed without technical detail, but falls under the same catalogue focus on photovoltaic power conversion. The range covers both low‑power (80 W) and high‑power (5 kW) inverter capacities, indicating capability to serve residential, commercial, and small‑scale irrigation applications. The presence of UPS‑type inverters suggests the supplier also targets backup power markets. Overall, the catalogue reflects a breadth of power conversion equipment commonly required in solar PV installations and off‑grid power systems.

Product Range and Specialties of Guangzhou Nianguan Electronics Technology Co., Ltd.

In the inverter segment, Chinese manufacturers typically deliver efficiencies of 93‑96 % for residential models and up to 98 % for commercial units, with total harmonic distortion (THD) below 3 % on the output waveform. Pure sine‑wave inverters are expected to meet IEC 62109‑1 safety standards and often carry UL 1741 for North American markets. Grid‑tie inverters usually support MPPT voltage windows between 120‑450 V and comply with IEEE 1547 interconnection rules. Solar charge controllers are commonly rated for 30‑60 A continuous current and include MPPT algorithms. Solar panels, when specified, are generally certified to IEC 61215 and IEC 61730, with wafer efficiencies of 19‑22 % and power outputs of 250‑400 W per panel.

The catalogue’s voltage converters (110 V‑220 V) fall under the static converter class, where buyers look for isolation ratings of at least 2 kV and overload protection complying with IEC 60984. For irrigation pump systems, 2.2 kW solar water pump inverters are usually paired with sub‑mersible pumps rated at 1‑2 HP, and the overall system efficiency is expected to exceed 80 % under standard test conditions. Packaging for these units typically involves wooden crates or metal pallets, allowing safe transport of items weighing up to 25 kg per unit, and a 20‑foot container can hold 30‑40 inverters depending on model dimensions.

Trade and Export Information - Guangzhou Nianguan Electronics Technology Co., Ltd.

Exports of power inverters and solar conversion equipment from China are directed mainly to Europe, North America, the Middle East, and Southeast Asia, where renewable‑energy installations are expanding rapidly. The HS‑code 8504.40 that appears in the catalogue is classified under “Static converters” and is subject to customs duties that vary by destination, often accompanied by a requirement for a test report confirming compliance with IEC 62109‑1/‑2. Commonly required certifications include CE marking for EU markets, UL 1741 for the United States, and ISO 9001 quality‑management certification for many importers.

Logistically, Chinese inverter suppliers typically ship using FOB Guangzhou or CIF Shanghai, with units packed in wooden crates on Euro pallets to fit standard 20‑ft or 40‑ft containers. Moisture‑resistant inner liners and anti‑static wrapping are standard to protect electronic components. Importers usually request a pre‑shipment inspection (PSI) covering visual, functional, and safety tests, and a certificate of origin to benefit from preferential tariff rates under various trade agreements. Buyers should also verify that the supplied documentation includes the product’s compliance test reports, CE/UL certificates, and a declaration of conformity.

Sourcing from Guangzhou Nianguan Electronics Technology Co., Ltd. - Buyer Guidance

When sourcing from Guangzhou Nianguan Electronics, buyers should request the latest IEC 62109 safety test report for each inverter model, as well as performance curves showing efficiency versus load. For grid‑tie units, an IEEE 1547 compliance statement and MPPT voltage range data are essential. Solar panel listings should be accompanied by IEC 61215 and IEC 61730 test certificates, along with measured module efficiency, cell type (monocrystalline or polycrystalline), and dimensions.

Typical minimum order quantities range from a single prototype unit for sample testing to 50‑100 units for mass production, with lead times of 30‑45 days after receipt of a purchase order and approved test documentation. Buyers should verify the material specifications of the voltage converter (copper winding gauge, silicon steel grade, housing corrosion protection) against the HS‑code 8504.40 filing. Requesting a pre‑shipment inspection report and a full packing list will help confirm that the cargo meets the agreed specifications before shipment.

What types of inverters are listed in the catalogue?

The catalogue includes DC‑to‑AC inverters ranging from 80 W to 5 kW, pure sine‑wave models up to 2 kW, grid‑tie and micro‑inverters for photovoltaic systems, and UPS‑type inverters with built‑in chargers.

Which product has an HS code provided?

The “Voltage converter 110v‑220v” is recorded under HS code 8504.40, classified as a static converter.

What certifications are typically required for the inverter products?

Buyers usually require IEC 62109 safety certification, CE marking for EU shipments, and UL 1741 for North American imports; these should be supplied as test reports or certificates of conformity.
