Energy Storage Systems to Maximize PV Generation and profits
The battery system extends the generation duration of renewable energy projects and generates additional revenue. Drawing on over 60 years of experience in power conversion design and manufacturing, we offer both AC-coupled and DC-coupled energy storage system solutions.
For both new and existing utility-scale PV plants, integrating an energy storage system transforms solar generation into a dispatchable, revenue-generating asset. With a well-designed storage system, the plant can supply power to the grid during periods of high electricity prices; meanwhile, when the PV inverter reaches its rated power limit, excess generation can be used to charge the battery system.

Hanlong is your trusted partner in developing optimal battery energy storage solutions for renewable energy projects. Our AC-coupled storage systems are ideal for adding storage capabilities to new or existing PV plants, enabling the capture, storage, and load management of PV energy while providing dynamic grid support.
Our DC-coupled power systems offer superior energy efficiency, lower installation costs, and higher utilization of PV generation. By integrating energy storage via DC-DC converters, these systems capture "peak-shaved" energy—power that exceeds the inverter's rated capacity and would otherwise be lost due to power curtailment—as well as energy generated during early morning and late afternoon hours when the PV array voltage is below the inverter's "wake-up" threshold.
