All-in-One Residential Energy Storage System

Product Description:
The All-in-One Residential Energy Storage System is an all-in-one cabinet-style product that combines a hybrid inverter with stackable battery modules. This system integrates three key functions: energy conversion, power distribution, and intelligent storage, automatically and efficiently managing the flow of energy between solar power, grid power, and battery storage. The built-in battery supports flexible expansion from a base capacity of 5kWh to 20kWh, adapting to different household power needs and embracing a wide range of applications.

Advantages and Features:
1. Easy Installation
The system integrates the hybrid inverter and battery modules into a single cabinet, eliminating the need for multiple devices, complex wiring, and separate installation spaces. Internal connections and commissioning are completed before shipment, simplifying on-site installation and reducing installation time.

2. Modular and Flexible Expansion
Based on current budgets and electricity usage habits, users can start with a base configuration of 5kWh. As household power needs increase (e.g., by adding an electric vehicle or new appliances), capacity can be easily expanded up to 20kWh by simply adding battery modules.

3. Intelligent Energy Management, Efficient and Autonomous

The system acts like a 24/7 home energy manager, automatically optimizing electricity usage through advanced algorithms. It prioritizes solar power, supplementing it with batteries when needed, and ultimately tapping into the grid's high-priced electricity. In areas with high electricity prices, it automatically charges during off-peak hours and discharges during peak hours, maximizing savings. All decisions are made automatically by the system, requiring no manual intervention, for a truly "set it and forget it" intelligent experience.

4. Voltage Compatibility, Hassle-Free Operation

The built-in hybrid inverter core features intelligent identification and wide voltage compatibility, automatically adapting to and providing stable access to both standard single-phase and more complex three-phase grid environments. This makes it suitable not only for apartments and villas, but also for small businesses and farms.

Application Scenarios:
● Green standard for new homes
● Energy storage upgrade for existing PV systems
● Cost reduction using stored power during peak hours
● Small commercial and off-grid applications

Nxten All-in-One Residential Energy Storage System combines a hybrid inverter with stackable battery storage (5~20kWh capacity) in a single unit. It automatically manages power from solar, grid, and battery sources, providing uninterrupted electricity during outages.

Typical Applications:

● Solar Self-Consumption: Stores excess solar energy during the day for use at night

● Backup Power: Provides an uninterrupted power supply during grid outages

● Peak Shaving: Reduces electricity costs by using stored energy during peak rate periods

● Off-Grid Living: Enables energy independence for remote locations

Features:

● 5kWh modular design for flexible expansion 5kWh

● Automatic identification

● Single & three-phase residential inverter compatible
