Import 300w 12v To 230v Modified Power Inverter — Buy in wholesale FOB from Supplier in China

This 300W modified sine wave inverter from Zhejiang Huapu Explosion-Proof Electric converts DC input at 12V, 24V, or 48V to AC 220V output at 50Hz or 60Hz. The compact aluminium and copper construction measures 134 x 106 x 64mm with a total weight of 0.9kg, suiting portable and fixed installations where space is constrained. Output power is rated 201-300W continuous, with a single AC output configuration. The HAPU brand or OEM-customised units are produced in Liushi Town, Yueqing, Zhejiang Province, a region with dense concentration of low-voltage electrical equipment manufacturing.

Modified sine wave output, also termed quasi-square or stepped waveform, switches the DC bus in a staircase approximation of sinusoidal AC rather than generating a pure sine wave. This topology uses fewer switching elements than pure sine designs, reducing cost and improving efficiency at the expense of compatibility with sensitive loads such as inductive motors, medical equipment, and certain power supplies. The copper transformer provides galvanic isolation and voltage step-up, while the aluminium heat sink and PC/ABS housing manage thermal dissipation and enclosure integrity. Input voltage selection between 12V, 24V, and 48V determines the primary winding configuration and current handling; confirm the specific variant before ordering.

Target applications include off-grid solar installations, vehicle-mounted power systems, camping and recreational vehicles, and emergency backup for small appliances. The 0.9kg mass and 134mm length suit mobile deployment. Commercial buyers should verify continuous versus surge power ratings, no-load current draw, and overload protection thresholds. The supplier offers OEM branding alongside HAPU-labelled product. No efficiency curve, total harmonic distortion figure, or operating temperature range is stated in the source materials; these parameters require direct confirmation with the supplier for system integration planning.

Zhejiang Huapu Explosion-Proof Electric Co, Ltd is located in Liushi Town, Yueqing, Zhejiang Province, China, postal code 325604. Yueqing is recognised as China's foremost cluster for low-voltage electrical apparatus manufacturing, with extensive supply chain integration for components, tooling, and testing infrastructure. The supplier holds harbour-tier trust status. Response rate and average response time data are not available, indicating that initial contact through the listed channels is necessary to gauge communication responsiveness and technical support depth. No information on year of establishment, registered capital, factory floor area, or employee count is provided in the source materials.

The company manufactures under the HAPU brand and accepts OEM orders, suggesting both branded distribution and private-label production capabilities. Its product focus spans explosion-proof electrical equipment and power conversion devices, though the specific scope of explosion-proof certification for this inverter model is not stated. No ISO certification, export licence details, or major client portfolio is disclosed. Buyers should request a company profile, factory audit report, and product-specific test certificates to assess manufacturing control and compliance with target market regulations such as CE-LVD, CE-EMC, or UL for North American markets.
