Global PV storage manufacturer
PV-Storage Integrated Factory
Founded in 2014, Hongyu has been a cornerstone of the PV industry for over a decade. As a leading Chinese provider, we have evolved beyond supply chain integration into a “Solar + Storage” Super Factory.
Our manufacturing core features a dual-track excellence: high-efficiency solar modules engineered through automated precision, and lithium battery systems built on high-stability LiFePO4 technology. By integrating cell sorting, smart BMS, and modular PACK assembly under one roof, we ensure seamless synergy between generation and storage. Leveraging our global collaborative network, Hongyu delivers integrated, high-performance energy solutions to key markets across North America, Europe, and Asia-Pacific.

Automated Sorting And Interconnection
The fully automated robotic arm precisely arranges the components, and low-temperature infrared non-destructive welding technology is used to eliminate thermal stress microcracks.
Fully Automated Lamination Process
The components enter a multi-cavity laminator, where the adhesive film undergoes perfect cross-linking and curing under high temperature and high vacuum conditions.
Robotic Arm For Precise Framing And Gluing
Industrial robots automatically press-fit anodized aluminum frames and evenly apply high-grade silicone. An IP68-rated junction box is then installed to ensure durability.
Lifepo4 Cells Undergo Full Capacity Testing
Only Grade A lithium iron phosphate cells are used, and 100% automatic capacity testing is performed upon arrival at the factory to strictly match internal resistance, voltage, and capacity.
High-Frequency Laser Welding Of Modules
The battery cell tabs are connected using automated, high-precision laser deep-penetration welding, eliminating the risk of overheating and poor soldering during charging and discharging.
BMS Integration And Testing
The battery integrates an intelligent BMS; The finished product undergoes rigorous charge-discharge cycle testing in a constant-temperature aging chamber to verify its absolute safety.
Zero Defect Policy
Rigorous Quality Control at Every Manufacturing Step
Our certification labs perform the industry’s most stringent cross-validation for both product lines. We ensure that not a single defective panel or risky battery cell reaches the market.
-
PV Products: Dual EL and Flash Test
X-ray imaging was used to detect hidden cracks, and dynamometer testing was conducted using an AAA-grade solar simulator to ensure positive tolerances.
-
Lithium Battery: Thermal Runaway and Puncture Testing
It uses the most stable and safest LiFePO4 and has passed drop, compression, and needle penetration tests to prevent it from igniting.
