Core Advantages
Duplex Power Generation
The back of the stack module generates electricity, the comprehensive power generation capacity is higher, and the power generation gain is verified by customers and third parties.
Smart Soldering
Uniform smart soldering increases the power and efficiency of the module, and improves the power load capacity.
Half-Cell Modules
The power of half-cell module increases, and the hot spot temperature reduces because of lower working current.
Electrically Compatible
Lower Operating current,Good for distributed generation applications; Matches with various inverters and optimizers; Avoids wiring loss.
Smart Module Packaging and Logistics
Smart module packaging solutions are used to achieve high reliability, low-cost transportation and logistics.
