• High-standard Material Selection + Full Inspection Quality Control, Laying a Solid Foundation for Product Quality

Core components include automotive-grade chips, high-precision tilt sensors and long-life electrolytic capacitors, all of which have passed extreme temperature tests ranging from -40℃ to 65℃ and repeated charge-discharge cycle tests, eliminating component failure risks at the source. The shell is made of V0-grade flame-retardant ABS+PC material and has obtained IP65 dustproof and waterproof certification, making it suitable for complex outdoor environments. Every finished product undergoes comprehensive tests including charge-discharge cycle, short-circuit protection and temperature protection before delivery, with a 100% qualification rate. Each unit is assigned a unique identification code, enabling full-process traceability of raw material batches and test data to ensure zero quality blind spots.

• Automated Manufacturing + Standardized Management, Ensuring Production and Delivery Quality

The production process adopts fully automated SMT chip mounting and wave soldering technologies, which precisely control the welding accuracy of circuit boards with a dimensional tolerance of ≤±0.2mm, avoiding process defects caused by manual operations. A three-inspection system (self-inspection, mutual inspection and final inspection) is implemented throughout the entire process, from component warehousing and assembly to finished product packaging. A production quality control report is retained for each batch of products. The standardized production line supports stable batch delivery with flexible capacity adjustment, satisfying both customized demands and mass production consistency.

• Multi-protection + Long-term Verification, Guaranteeing Stable Operation in All Scenarios

The product is built-in with six protection mechanisms against overcharging, over-discharging, overloading, short-circuiting, reverse connection and lightning surges. It can respond to abnormal conditions such as grid fluctuations and sudden environmental changes in real time, and cut off the fault circuit instantly to protect the safety of both the photovoltaic system and the controller itself. Each product has passed a 1000-hour full-load continuous operation test. The after-sales team provides 7×24-hour response, offering remote fault diagnosis and on-site technical support. This ensures the controller operates stably throughout its 10-year designed service life and minimizes the operation and maintenance costs of the photovoltaic system.
