Import 250w/300w Micro Inverter — Buy in Bulk from Supplier in China

The 250w/300w micro inverter from New Sun Pv Technology Co., Ltd. is a compact DC-to-AC conversion unit rated for 250 - 320 W output, designed for modular solar installations where panel-level optimisation matters. It accepts 12 V, 24 V, or 48 V DC battery or array input and delivers AC at 110 V - 230 V, covering most global single-phase grid standards. A copper-wound transformer forms the core power stage, a construction choice that typically reduces core losses compared to aluminium alternatives. The unit is built for residential rooftops, commercial arrays, and off-grid battery systems where individual panel monitoring and rapid shutdown compliance are increasingly required.

Micro inverters of this class generally employ IP65-rated enclosures to resist dust ingress and low-pressure water jets, though buyers should confirm the exact IP rating with the supplier. The wide input voltage range, 110 V - 230 V AC output, suggests a universal-voltage design rather than region-locked hardware, which simplifies spare-parts stocking for international installers. Copper transformer construction also implies better overload tolerance and lower operating temperature rise under continuous duty. Typical industry efficiency for this power class ranges from 95 % to 97 % CEC weighted efficiency, and buyers should request the specific MPPT efficiency and maximum DC voltage rating to ensure compatibility with their module string configuration.

Target buyers include solar EPC contractors, residential installers, and off-grid system integrators in markets with 230 V nominal grids (Europe, Australia, much of Asia) and 120 V regions (North America, Japan). The 250 - 320 W power band aligns with common 60-cell and 72-cell module outputs, making it suitable for retrofit or new-build rooftop projects. Packaging and carton dimensions are not stated in the listing, so confirm unit weight, shipping carton quantity, and whether wall-mount brackets are included. The supplier quotes FOB and CIF terms; importers should verify Incoterms 2020 application, marine insurance coverage, and whether the quoted FOB port is Shenzhen, Guangzhou, or another southern China gateway.

New Sun Pv Technology Co., Ltd. is located in Chang'an Town, Dongguan City, Guangdong Province, a manufacturing corridor in the Pearl River Delta with extensive electronics and electrical component supply chains. The company's registered address is Jiawen Park, Hengzeng Street, Xin'an Community. It holds an imported supplier tier on the platform and a harbor trust tier. The response rate is shown as 0.00 % with zero average response hours, which indicates that response data is either not collected or not disclosed; buyers should treat direct communication as untested and initiate contact early to gauge responsiveness.

The supplier profile does not state year of establishment, factory floor area, annual capacity, headcount, revenue, or specific certifications held. It does not list named clients or reference projects. The listing mentions ISO and CE certifications in the source description, but these are not independently verified in the profile data, so buyers should request current certificate copies with scope and validity dates. The company's product focus appears to be solar power conversion equipment, specifically micro inverters in the sub-400 W residential segment. No information is given about R&D staff, in-house testing laboratories, or after-sales service infrastructure.
