Residential High Voltage Lithium Batteries
JAXING FEYA NEW ENERGY CO., LTD. presents its advanced series of high-voltage lithium batteries designed for residential energy storage, delivering reliable power solutions from 20KWH to 60KWH. These rack-mounted systems are engineered with LiFePO4 battery technology, ensuring long cycle life, enhanced safety, and stable performance.
The product line includes five models-FY-GY 20KWH to 60KWH-each offering high energy density and a wide working voltage range. With nominal voltages from 204.8V to 512V, these batteries support efficient energy storage and are compatible with most leading inverters. The built-in intelligent BMS provides precise monitoring and control, ensuring operational safety and longevity.
Designed for flexibility, these batteries support multiple installation options including wall-mounted, floor-standing, and side-mounted configurations. Their compact and modular design helps save space and reduces installation costs. With a cycle life of over 6000 cycles and a low self-discharge rate, these systems offer exceptional reliability for daily use.
Ideal for renewable energy applications, these batteries operate efficiently within a broad temperature range and feature IP20 waterproof protection. Peak charge/discharge current reaches 150A, meeting high-power demands.
Feya New Energy also offers OEM/ODM services, providing tailored battery solutions for telecom, commercial, and renewable energy projects.
Our company is located in China,has been engaged in the new energy industry for over ten years and possesses rich knowledge and experience. We have a sophisticated supply chain in each module of new energy, capable of providing customers with high-quality, cost-effective and even more excellent services.
For products that match batteries, such as solar panels and inverters, we also have relatively in-depth cooperation with many well-known brands. All customers are welcome to inquire about prices with our company. We will provide you with quotations in a timely manner and offer occasional promotional product.
