The CTECHI All-in-One Residential Energy Storage System (ESS) combines cutting-edge LiFePO4 battery technology with a powerful off-grid or hybrid inverter, offering an efficient and compact energy storage solution for modern homes. Designed for seamless integration with off-grid or on-grid and off-grid applications, this all-in-one system simplifies energy management by connecting directly to existing PV panels, mains power, and even diesel generators. It provides a reliable and eco-friendly way to store excess solar power during the day and deliver uninterrupted energy during peak hours or outages.
Equipped with premium LiFePO4 battery technology, the system delivers over 6000 cycles, ensuring durability and reliable performance for years. UPS-level switching within ≤10ms, it provides uninterrupted power for critical loads.
This integrated solution combines the inverter and battery, eliminating the need for complex installations. It supports direct connection to PV panels, the grid, and additional power sources, offering flexibility and ease of setup for residential energy storage systems.
Featuring patented LFP module technology, the system ensures consistent performance and enhanced safety. It supports parallel configuration of up to 8 systems, enabling scalability to meet larger energy demands.
The system is equipped with WiFi-enabled smart management, allowing users to monitor and control energy usage via a dedicated app. This ensures energy efficiency and convenience at your fingertips.
