Our 50KWh Residential Energy Storage System is a next-generation, high-capacity power storage solution engineered for luxury residential properties, light commercial facilities, and microgrid applications. Built with top-tier cobalt-free lithium iron phosphate (LiFePO4) battery technology, this high-capacity residential ESS delivers exceptional energy density, superior safety, and stable long-term operation, with flexible scalability from 50kWh up to 320kWh. It is the premier choice for high-end real estate developers, microgrid contractors, commercial facility integrators, and renewable energy engineering firms seeking a robust commercial grade home energy storage system to achieve full energy independence, maximize renewable energy utilization, and deliver reliable backup power for large-scale power demands.
This large-scale residential power backup system is based on a modular cabinet design, with a base capacity of 50kWh that can be seamlessly expanded up to 320kWh via parallel module connection. It delivers a continuous nominal power of 8.1kW and a peak power of 9.3kW @ 3s, easily supporting full-house power supply for luxury villas, multi-level residences, and small commercial facilities, even during extended grid outages.
At the heart of this off-grid solar energy storage battery is premium LiFePO4 battery chemistry, which offers unmatched thermal stability, deep cycling capability, and a long service life. The advanced multi-level BMS provides real-time cell balancing, fault detection, and comprehensive protection against overcharge, over-discharge, over-temperature, and short circuits, eliminating safety risks for large-capacity energy storage applications.
The integrated intelligent energy management system (EMS) automatically balances energy storage, grid interaction, solar input, and load distribution, optimizing energy usage and reducing peak demand costs. It also features a cloud-connected monitoring platform, enabling partners and end users to access real-time performance tracking, remote diagnostics, and firmware updates from anywhere in the world.
With an IP66 protection grade, this 50KWh residential energy storage system is suitable for both indoor and outdoor installation, adapting to diverse environmental conditions. The floor-mounted cabinet design features a compact footprint, simplifying installation and reducing space requirements for large-scale projects.
