PRODUCTION LINES
OUR EXHIBITION
We provide comprehensive B2B Technical Support, including system sizing consultations, remote diagnostic assistance, and localized marketing materials. Our Solar Inverters and ESS products typically carry a 5 to 10-year performance warranty. We also maintain a specialized engineering team to assist B2B partners with troubleshooting and firmware updates, ensuring the stability and longevity of every Renewable Energy Storage project we supply.
Yes, scalability is a core advantage of our Modular Energy Storage architecture. Our Stackable Battery Storage units and Hybrid Inverters support parallel configurations. For instance, up to 15 battery modules can be synchronized to create a high-capacity Solar ESS, and multiple inverters can be paralleled to handle larger loads. This allows EPC contractors to deploy tailored energy solutions that grow alongside the client's energy demands.
Every Jiahongyu LiFePO4 Battery module is equipped with an industrial-grade Smart BMS (Battery Management System). This system provides real-time monitoring of cell-level telemetry, including voltage balancing, thermal management, and over-current protection. With Grade-A cells, our storage units offer over 6,000 deep-cycle lives, providing a high-ROI Lithium Battery Backup solution for mission-critical residential and commercial applications.
A: Our Hybrid Inverter series is engineered with a multi-protocol communication interface, supporting CAN, RS485, and RS232. This ensures seamless integration with leading LiFePO4 battery brands and allows for firmware adjustments to meet specific regional grid codes (such as CE, AS4777, or IEEE 1547). For system integrators, this flexibility simplifies the installation of a comprehensive Solar Energy Storage System across diverse international markets.
