Integrated Photovoltaic-Energy Storage-Hydrogen Production System Solution

This integrated photovoltaic-energy storage-hydrogen production system solution provides both standardized and differentiated models approaches for large-scale power station utility-scale deployment.

It combines high-density, modular AC-coupled storage featuring cluster-level liquid cooling, fire-isolated design, and LFP battery safety with specialized power interfaces. Unique AC power supply capabilities enable zero grid feedback, seamless transition between renewables and grid power, and soft transfer technology to eliminate grid impact during switching. Its differentiated DC-powered solution provides an end-to-end PV-storage flexibility option, claiming approximately 5% higher efficiency versus traditional AC systems. Supporting hardware includes a solar charge controller with industry-leading 12 MPPT channels per module, wide-input DC-DC converters ensuring flexible voltage matching, and highly efficient (>98%) multi-source power inverters suitable for diverse loads. Core benefits emphasize safety, high efficiency through optimized power conversion, resilient environmental protection (IP65/IP66, C5), modular scalability, and reduced installation complexity via features like string pair consolidation. This holistic system targets significant operational efficiency and reliability for large-scale renewable energy integration.
