We support electrical solution assessment and OEM design covering solar input, charge management, interfaces, load requirements and compatibility with third-party storage devices. Each system is configured around the target equipment, environment and customer-nominated power platform, then validated for production.
Flexible Solar Integration Beyond the Backpack
The solar backpack is our benchmark application, proving how flexible PV can be integrated with outdoor fabrics, product structures and charging functions. We apply the same development approach to tents, bags, textile products and other portable carriers. Grunsolar delivers an integration solution from requirements to finished product—not simply bag production.
Our Products
Green Energy is a new energy company integrating innovation, sustainability, and a global perspective.
Solar, Power Management and Storage Compatibility
Products Designed from the Use Case Outward
For outdoor recreation, fieldwork, emergency support and scientific expeditions, we define the user, environment, target devices, power demand and operating time first. Solar modules, materials, structure, interfaces and protection are then selected around the real task.

Ferrous Oxalate Method
Using ferrous oxalate as iron source can produce materials with higher purity and better crystallinity, conducive to obtaining fine and uniform particles, though the sintering process faces greater environmental pressure.

Liquid-Phase Method (Hydrothermal Synthesis)
Achieving nanometer-level uniform crystallization in high-pressure water environments, with good product consistency but higher equipment requirements. Dynanonic is the representative enterprise.

Technology Evolution:
High-Compaction Density Direction
03
Energy storage batteries are evolving from 280Ah to 314Ah large cells, requiring cathode materials with higher compaction density. The industry has developed to fourth-generation products (powder compaction density 2.6-2.7g/cm³), optimizing microstructure through secondary sintering processes to pack more active materials per unit volume, significantly improving energy density.
