About QueensWing Solar Energy - DC, AC Inverters & Converters Supplier in China

QueensWing Solar Energy is listed in China with a catalogue of six active products. The supplier’s top categories are DC, AC Inverters & Converters and Battery Testers & Chargers, and the six items cover pure sine wave inverters, off‑grid solar inverters and inverter‑charger combinations. Two of the listed items - the 1000W Solar Power Inverter with Charger and the 1000W Pure Sine Wave Inverter (QW‑P1000) - carry the HS code 8504.40, which classifies them as electrical power converters. The catalogue also includes generic entries such as "Power Inverter With Charger" and "Inverter With Chargers" that do not specify an HS code. Materials mentioned for the coded products include aluminum‑alloy housing, copper windings and printed circuit board components, typical of modern inverter construction.

Product Range and Specialties of QueensWing Solar Energy

The product range consists of a 1000W pure sine wave inverter (QW‑P1000), a wattage off‑grid solar inverter, a 1000W solar power inverter with charger (HS 8504.40) and several inverter‑with‑charger variants. In the broader industry, 1000W inverters are usually rated for input voltages of 12 V/24 V/48 V DC, output frequencies of 50/60 Hz, and efficiencies above 90 %. Pure sine wave units commonly meet IEC 62109 safety standards and are tested for total harmonic distortion (THD) below 3 %. Battery charger modules attached to inverters typically support 10 - 30 A charge currents and include MPPT (Maximum Power Point Tracking) control. Buyers often look for CE, UL or IEC certifications and may request ISO 9001 quality‑system documentation from Chinese manufacturers.

Trade and Export Information - QueensWing Solar Energy

Chinese inverter manufacturers export heavily to Europe, North America and the Middle East, where renewable‑energy installations drive demand for off‑grid and hybrid systems. The HS code 8504.40 covers static converters, and customs authorities in importing countries frequently request test reports confirming compliance with IEC 62109, IEC 61730 (photovoltaic modules) and RoHS restrictions on hazardous substances. Typical export packaging involves wooden crates or cardboard pallets that fit a 40‑foot container, with freight terms such as FOB Shanghai or CIF destination. Chinese exporters often obtain CE marking for EU markets and may provide UL listings for the United States, although these certifications must be verified by the buyer. Export documentation usually includes a commercial invoice, packing list, certificate of origin and, where required, a test certificate from an accredited lab.

Sourcing from QueensWing Solar Energy - Buyer Guidance

When sourcing from QueensWing Solar Energy, request copies of CE or UL certificates, as well as IEC‑62109 test reports that detail efficiency, overload capacity and THD. Verify the material specifications for the housing (aluminum alloy) and windings (copper) to ensure they meet the thermal and mechanical requirements of the intended installation. Ask for a functional sample or a factory‑tested unit before placing a bulk order, and confirm the minimum order quantity (MOQ), which commonly ranges from 50 to 200 units for 1000 W inverter models. Clarify lead times, which for Chinese manufacturers are typically 4‑6 weeks after order confirmation, and agree on packaging details such as crate dimensions and moisture‑proof sealing.

What is the HS code for the 1000W Solar Power Inverter with Charger?

The 1000W Solar Power Inverter with Charger is listed under HS code 8504.40, which classifies it as an electrical power converter.

Which safety standards are commonly required for 1000W pure sine wave inverters?

Buyers usually require compliance with IEC 62109 for safety, IEC 60335‑2‑24 for appliance performance, and CE or UL certification depending on the destination market.

What material specifications should I verify for the inverter housing?

The catalogue notes an aluminum‑alloy housing; buyers should confirm alloy grade, thickness and corrosion‑resistance coating to match the installation environment.

Are test reports for efficiency and harmonic distortion available?

Manufacturers typically provide test reports showing efficiency above 90 % and total harmonic distortion (THD) below 3 % for pure sine wave output, which should be requested before purchase.

What is a typical minimum order quantity for these inverters?

For 1000 W inverter models from Chinese suppliers, MOQs commonly fall between 50 and 200 units, but the exact figure should be confirmed with the supplier.

What packaging and shipping format is used for the inverters?

Inverters are usually packed in wooden crates or reinforced cardboard pallets, sized to fit a 40‑foot container, and shipped under FOB Shanghai or CIF terms.

Which certifications should I request from QueensWing Solar Energy?

Request copies of CE marking, UL listing (if targeting the US), IEC‑62109 safety test reports and any ISO 9001 quality‑system certificates the supplier can provide.

What lead time should I expect for a bulk order?

Lead times for Chinese inverter manufacturers are typically 4 to 6 weeks after order confirmation, subject to production scheduling and shipping arrangements.
