Yueqing Bangzhao Electric Co., Ltd.

Based in China, Yueqing Bangzhao Electric Co., Ltd. lists 43 active products across the categories of DC/AC inverters & converters, solar power equipment, batteries & chargers, welding & wire mesh machinery, electric components and electric connectors. The catalogue is dominated by items classified under HS chapter 85, especially HS 8504.40 for power converters and inverters, with a single product under HS 8537.10 for a PV junction box. The product list includes a 120 VDC‑to‑380 VAC off‑grid motor converter, a three‑phase 3700 HP solar pump inverter, a 100 A solar charge regulator for a 96 V battery bank, several PV combiner boxes, high‑voltage wind charger controllers, a 200 kW PV inverter, a 1000 V DC PV junction box (HS 8537.10) and numerous grid‑tie and off‑grid inverters ranging from 800 W to 200 kW. Materials noted in the catalogue feature steel housings, copper windings, aluminum heat sinks, polycarbonate enclosures and Mitsubishi IPM power modules.

The catalogue covers a spectrum of inverter technologies: low‑frequency 10 kW and 3‑phase 380‑480 V units, sinusoidal output models, hybrid off‑grid converters and high‑voltage DC‑to‑AC converters. Typical industry grades for such equipment include IEC 62109 safety compliance, IEC 61727 charge‑controller standards and efficiency levels above 95 % for modern silicon‑based inverters. Common specifications observed in this segment are input voltage ranges of 100‑800 V DC, output frequencies of 50/60 Hz, THD <3 %, IP65 enclosure ratings and protection class UL 94 V‑0 for polymer parts. Materials frequently used in Chinese‑origin inverter production match the catalogue’s descriptions: steel or aluminum alloy frames for mechanical strength, copper busbars and windings for conductivity, and semiconductor modules such as Mitsubishi IPM or IGBT arrays for power conversion. PV junction boxes typically employ polycarbonate (UL‑94 V‑0) housings, copper busbars of 99.9 % purity and EPDM rubber gaskets to meet IEC 60529 ingress protection requirements.
