Lithium Energy Storage Systems for Solar, Telecom & Commercial Backup Power

We offer multiple rechargeable battery technologies to meet different energy storage requirements. Our product range includes LiFePO₄ (Lithium Iron Phosphate) batteries for residential, commercial, telecom, and off-grid solar applications, Lithium-ion (NCM) batteries for applications requiring higher energy density, and selected Sodium-ion battery solutions for emerging energy storage projects. Our engineering team can recommend the most suitable battery chemistry based on your application, operating environment, and budget.

Selecting the right battery capacity depends on several factors, including your load power (W or kW), system voltage, required backup time, local peak sun hours, and the expected solar energy generation. Future system expansion should also be considered during system design. Our engineers can help calculate the appropriate battery capacity to ensure reliable performance while avoiding unnecessary investment.

Yes. Our lithium battery systems support CAN and RS485 communication protocols, allowing compatibility with many leading inverter brands. Battery communication parameters can be configured to match different inverter protocols. Selected battery models also support Wi-Fi or 4G remote monitoring, enabling users to monitor battery status, operating data, and system performance through a mobile application.

Yes. Most of our lithium battery systems are designed for future expansion through parallel connection. For optimal performance and safety, expansion batteries should have the same battery voltage, capacity, battery chemistry, and BMS version. If future expansion is planned, we recommend discussing your requirements with our engineering team during the initial system design.

Our energy storage systems are designed for a wide range of applications, including residential solar energy storage, commercial and industrial ESS, telecom backup power, off-grid solar systems, remote monitoring stations, CCTV security systems, and renewable energy projects. Different battery configurations are available to meet varying power demands, installation environments, and backup time requirements.

Yes. All JOYVOIT lithium battery systems include an intelligent Battery Management System (BMS). The BMS continuously monitors battery voltage, current, temperature, and cell balance while providing protection against overcharging, over-discharging, overcurrent, short circuits, and over-temperature conditions. It also supports communication with compatible inverters to improve overall system performance and operational reliability.

Yes. We provide OEM and ODM battery manufacturing services for distributors, system integrators, and project developers worldwide. Customization options include battery housing design, capacity, communication protocols, branding, labels, packaging, and selected hardware configurations. Our engineering team can also assist with customized battery solutions for specific project requirements.

The service life of a lithium battery depends on factors such as battery chemistry, cycle life, depth of discharge (DOD), operating temperature, charging conditions, and maintenance. Our LiFePO₄ battery systems typically provide 6,000–8,000 charge cycles under recommended operating conditions. For longer battery life, we generally recommend designing the system around an 80% Depth of Discharge (DOD), which helps balance usable capacity and long-term durability.

The standard warranty period depends on the specific battery model and application. Most JOYVOIT lithium battery systems are supplied with a limited product warranty, while the expected service life is significantly longer under recommended operating conditions. Please contact our sales team for model-specific warranty information.

Depending on the product model and target market, our battery systems can be supplied with certifications such as CE, UN38.3, MSDS, IEC, and other required compliance documents. Please contact us to confirm the certifications available for your selected product.
