JM 48V 800Ah 40kWh LiFePO4 Battery for Home Energy Storage

PRODUCT DESCRIPTION 51.2V 800Ah 40kWh LiFePO4 Battery The JM-JS-51.2V800Ah is a 51.2V 800Ah LiFePO4 battery with 40kWh of energy capacity, designed for home energy storage, solar power storage and backup power applications. With 80% depth of discharge (DoD), an 8000-cycle design and a smart BMS, the battery is built for long-term energy storage use. For solar installers, distributors and system integrators, this large-capacity LiFePO4 battery provides a practical energy storage option for residential projects that require substantial energy storage capacity and reliable backup power. High-Capacity 40kWh Energy Storage With a rated capacity of 40kWh , the battery is designed for residential energy storage applications where a larger energy reserve is required. The 51.2V 800Ah configuration provides a substantial storage capacity for solar energy systems and backup power applications. This makes it suitable for projects where installers need to consider both daily energy storage and backup requirements. 80% DoD for Usable Energy The battery supports 80% depth of discharge (DoD) . For an energy storage system, DoD indicates how much of the battery's stored energy can be used during a discharge cycle. An 80% DoD provides a defined usable portion of the battery capacity while supporting the intended operating characteristics of the system. For installers and system integrators, DoD is an important specification to consider when sizing a battery system according to the customer's d Sold on JM Energy Factory LiFePo4 Lithium Solar Battery manufacturer supplier (https://jmbatteries.com/products/jm-48v-800ah-40kwh-lifepo4-battery).
