High-Capacity Battery Storage for Home Backup and Off-Grid Solar Power

Take greater control of your energy with the RUiXU Lithi2-20 20kWh Lithium Iron Phosphate Battery. Designed for residential solar energy systems, off-grid properties, and light commercial power applications, this high-capacity battery delivers 20kWh of nominal energy storage, 51.2V nominal voltage, and 392Ah capacity. Store electricity generated by your solar panels during the day and use that stored energy when the sun goes down, solar production drops, or a power outage interrupts your connection to the utility grid. With substantial storage capacity in one battery, the Lithi2-20 provides a powerful foundation for building a more capable home backup or off-grid power system.

Built with brand-new Grade A LiFePO4 cells, the RUiXU Lithi2-20 is engineered for long service life, dependable energy storage, and demanding operating environments. Its stated cycle life of 9,500+ cycles at 80% depth of discharge and 15-year design life make it a compelling choice for homeowners investing in long-term battery storage. Whether you are upgrading an existing solar installation, building an off-grid cabin power system, or adding energy storage to a home or business, the Lithi2-20 combines high capacity, intelligent battery management, and expandable system design.

Key Features of the RUiXU Lithi2-20 20kWh Battery

Store more energy with 20kWh of high-capacity LiFePO4 storage. The Lithi2-20 combines 51.2V nominal voltage and 392Ah capacity to deliver 20kWh of nominal energy in a single battery cabinet. Its recommended charge and discharge current is 140A, with a maximum continuous charge and discharge current of 200A. Peak discharge capability reaches 240A for 15 seconds and 360A for 1 second, supporting short-duration demand from compatible power systems. Actual usable power depends on the inverter, connected loads, system configuration, and battery operating conditions. With support for up to 32 batteries in parallel, the system can scale from 20kWh to a potential 640kWh of nominal storage for larger residential and light commercial applications.

RUiXU Lithi2-20 Applications: Home Backup, Off-Grid Cabins, and Solar Energy Storage

For homeowners building a home solar battery backup system, the RUiXU Lithi2-20 provides 20kWh of nominal storage for electricity generated by a compatible solar array. Store surplus solar energy during daylight hours and use it in the evening, overnight, or during utility power interruptions. When paired with a properly sized hybrid inverter, the battery can support selected household circuits or a broader range of home loads, depending on inverter output, battery capacity, and simultaneous appliance demand. It is a practical foundation for homeowners looking to increase solar self-consumption, reduce reliance on the power grid, and improve backup capability during outages.

For remote properties, cabins, workshops, and homesteads, the Lithi2-20 offers substantial storage for an off-grid solar power system. Pair it with compatible solar panels and an inverter to supply stored energy for refrigeration, lighting, communications equipment, electronics, pumps, and other appropriately sized loads. Its integrated self-heating feature is particularly useful for installations that experience cold weather, while IP55 protection adds flexibility when planning a suitable installation location. Whether you are building a cabin solar system, upgrading a shed power setup, or creating a larger off-grid battery bank, the Lithi2-20 gives you room to design around your actual daily energy requirements.

The Lithi2-20 is also suited to larger residential and light commercial energy storage projects where future expansion is important. Start with one 20kWh battery and add compatible units in parallel as your energy requirements increase, up to the stated 32-unit configuration. This scalability can support growing homes, workshops, agricultural properties, and businesses that need additional stored electricity. Before installation, confirm inverter compatibility, charge and discharge limits, communication protocols, cable and busbar requirements, and the total storage capacity needed for your application.
