Import 22v To 60v Grid Tie Solar Power Inverter — Buy in Bulk from Supplier in China

This grid-tie solar power inverter accepts a DC input range of 22 V to 60 V, making it compatible with 60-cell and 72-cell photovoltaic modules commonly deployed in residential and small commercial arrays. The unit converts variable DC output from solar panels into AC power synchronised with the utility grid, with no battery storage required. Built-in protection covers over-voltage, over-current, and short-circuit conditions. The compact and lightweight physical design targets straightforward wall or rack mounting. The supplier describes the inverter as suitable for both on-grid residential installations and commercial building-integrated applications.

Grid-tie inverters in this voltage class typically employ high-frequency switching with IGBT or MOSFET power stages and maximum power point tracking (MPPT) to harvest peak energy across varying irradiance and temperature conditions. Conversion efficiency is a critical performance metric; standard units in this class typically reach 93 to 97 percent peak efficiency depending on topology and loading. Input voltage range flexibility allows series string configurations of two to four standard 60 W panels in series, though exact string sizing must respect local temperature coefficients. The enclosure should carry an appropriate ingress protection rating for intended installation, typical IP65 for outdoor exposure.

Target buyers include solar EPCs, electrical contractors, and distributors serving residential retrofit and commercial rooftop markets. Applications span grid-connected PV systems where net metering or feed-in tariff structures apply. The inverter lacks galvanic isolation unless specified, so confirm transformerless or transformer-based topology if local utility mandates earth fault protection. Before purchase, confirm with Guangzhou Nianguan the exact AC output voltage, frequency, and grid compliance standard, as these vary by destination country and determine certification acceptability.

Guangzhou Nianguan Electronics Technology Co., Ltd. is located at R326, Floor 3, Jin Fu Building, No. 90 Qifu Road, Guangzhou 510810, Guangdong Province, China. The supplier carries a harbor trust tier and an imported tier classification on the platform, with a recorded response rate of 0.00 percent and zero average response hours. The profile does not disclose year of establishment, registered capital, number of employees, or annual revenue. Buyers should initiate contact to assess responsiveness and request a copy of the business licence and any ISO quality system certification held.

The company operates from Guangzhou, a major electronics manufacturing and trading hub in southern China with established logistics links to Shenzhen port and Hong Kong. The listing presents Nianguan as a supplier of solar power inverters without indicating whether it manufactures in-house or sources from OEM partners. No information is provided about engineering staff, production capacity, export experience, or reference projects in specific countries. Given the address in a multi-tenant commercial building rather than an industrial zone, buyers are advised to verify manufacturing versus trading status through factory audit or video verification before committing to volume orders.
