ESS Energy Storage System Stackable All In One ESS 1200W 4.02kWh Energy Storage System Lithium Battery
The RSUN Stacked RSN Series is a streamlined residential energy-storage solution built around a flexible, modular battery stack. Its plug-and-play architecture allows each unit to be added or removed with ease, giving homeowners a simple path to expand capacity as their energy needs grow. By storing excess solar power generated throughout the day, it delivers reliable home backup and meaningful reductions in grid consumption.
With built-in WiFi and Bluetooth connectivity, the system offers real-time oversight and control through a mobile app, whether the user is at home or away. Its upright, floor-mounted design keeps the footprint minimal, making it a smart fit for compact indoor spaces while combining dependable performance with modern, intuitive energy management.
• High-durability Li-ion battery (8000-cycle life) plus MPPT solar charging built in.
• Adjustable energy priority, choose solar, battery, or grid as the main source.
• Broad AC input tolerance for regions with unstable power.
• Comprehensive safeguards: discharge, load, temperature, and short-circuit protection.
• Stackable, modular layout for simple upkeep and capacity upgrades.
