The RB series energy storage battery system mian characteristics

1. High-efficiency energy storage and flexible charging and discharging

The household energy storage battery adopts high-energy-density LFP batteries, with an energy storage efficiency of over 90%, and supports fast charging and discharging. For instance, a battery with a standard voltage of 48V and a capacity of 200AH can store approximately 10kWh of electricity, meeting the minimum daily electricity demand of an ordinary household.. At the same time, the system supports priority charging of renewable energy sources such as solar and wind power, and is compatible with energy storage during off-peak hours of the power grid, achieving "low-cost electricity storage and high-price electricity consumption". Some high-end models also support bidirectional charging and discharging, selling electricity in reverse during peak grid demand periods to generate additional revenue.

2. Intelligent Energy Management System (EMS)

With built-in AI algorithms and Internet of Things (IOT) technology, energy storage batteries can analyze household electricity usage habits, electricity price fluctuations and weather data in real time, and automatically optimize charging and discharging strategies. For instance, in areas with time-of-use electricity pricing, the system charges during the low electricity price period in the early morning and supplies power to households during the evening rush hour, saving electricity bills to the greatest extent. Users can also remotely monitor the battery level and set the priority of electricity usage (such as giving priority to refrigerators and medical equipment) through the mobile phone APP, and interact with smart home devices to achieve full-process automation of "electricity usage - storage - control".

3. High safety and long service life

The LFP blade battery of the same type as BYD vehicles can effectively prevent combustion and explosion even in the case of high temperature or short circuit, and has passed international safety certifications such as UL 9540 and IEC 62619. The battery pack is equipped with multiple protection mechanisms, including temperature monitoring, over charge/over discharge protection, and self-check for faults, ensuring a service life of up to 10 to 15 years (with over 6,000 charge and discharge cycles). Furthermore, the modular design enables the system to operate at a reduced level even when a single battery fails, ensuring that the basic power supply is not interrupted.

4. Environmental Protection and Sustainability

Household energy storage batteries significantly reduce reliance on fossil fuels by maximizing the utilization of clean energy such as solar power. Take a typical 5kW photovoltaic +10kWh energy storage system as an example. It can reduce carbon dioxide emissions by 3 to 5 tons annually, which is equivalent to the environmental benefit of planting 150 trees. Meanwhile, over 95% of the materials of the battery can be recycled, avoiding the pollution problems of traditional lead-acid batteries and aligning with the global carbon neutrality goal.

5. Emergency power supply and off-grid capacity

When extreme weather conditions such as typhoons and earthquakes cause the power grid to collapse, energy storage batteries can switch to off-grid mode within 0.02 seconds and continuously supply power to critical loads such as lighting, communication equipment, and medical instruments (typically supporting 12 to 24 hours). Some systems can also be expanded to the "whole-house backup power" mode to meet the high-power demands of air conditioners, kitchen appliances, etc., achieving energy self-sufficiency for more than 72 hours, which is particularly suitable for areas with unstable power grids.

6. Flexible adaptation and scalability

The home energy storage battery adopts a modular design, with a capacity that can be expanded from 5kWh to over 50kWh, making it suitable for various scenarios such as single-family villas, apartments, and small shops. For instance, users can first install the basic capacity to meet their daily needs, and then gradually increase the configuration later based on demands such as electric vehicle charging and home expansion. In addition, the system is compatible with photovoltaic panels, inverters and V2L type charging piles of different brands, thereby building an integrated energy network.
