Import 500wdc To Ac Modify Power Inverter With Charger — Buy in Bulk from Supplier in China

The 500W DC to AC modified sine wave inverter with integrated charger converts direct current to alternating current for industrial and commercial installations. It delivers a continuous output of 500W with a peak surge capacity of 1000W, allowing motorised or inductive loads to start without tripping protection. The unit incorporates a built-in battery charger, eliminating the need for separate charging hardware in backup power configurations. Multiple protection circuits, including overload shutdown and thermal cut-off, guard against fault conditions. Guangzhou Nianguan Electronics Technology Co., Ltd. supplies this model from Guangdong province.

The modified sine wave output waveform is suitable for resistive loads and many electronic devices, though some sensitive equipment may require pure sine wave conversion. The compact, lightweight housing simplifies wall or rack mounting in mobile and stationary applications. Standard industry practice for this class of inverter includes input undervoltage and overvoltage lockout to protect the battery bank; buyers should confirm the exact DC input range with the supplier. Typical operating efficiency for modified sine wave inverters in this power class ranges from 80% to 90% at rated load. Ambient temperature derating and fan noise levels are additional parameters worth verifying before purchase.

Primary applications include off-grid solar installations, vehicle-mounted power systems, telecommunications shelters, and emergency backup supplies. The charger function suits installations where battery maintenance cannot be handled by external equipment. Importers should confirm the AC output frequency (typically 50Hz or 60Hz), nominal DC input voltage, and whether the unit supports battery chemistry types such as sealed lead-acid or lithium-ion. Packaging and Incoterms need clarification with the supplier, as these details are not stated in the listing. FOB Guangzhou or CIF terms are common for electronics exports from this region, but must be negotiated directly.

Guangzhou Nianguan Electronics Technology Co., Ltd. is located at R326, Floor 3, Jin Fu Building, 90 Qifu Road, Guangzhou, Guangdong, 510810, China. The supplier is listed as an imported-tier participant on the platform with a harbour trust designation. The response rate is shown as 0.00% and average response time is recorded at zero hours, which indicates no inquiry activity has been logged or response metrics are unavailable. No information on year of establishment, factory size, employee count, or annual revenue is provided in the source profile.

The company address places it in Guangzhou's commercial district rather than an industrial zone, suggesting it may operate as a trading office or distributor in addition to any manufacturing role. The listing does not specify ISO certification, factory audit results, or export licence details. Buyers should request a business licence, VAT invoice capability, and any applicable product certifications such as CE, RoHS, or CCC directly from the supplier before placing an order. The harbour trust tier is the entry-level verification status on this platform, so additional due diligence is advisable.
