RH Series household ESS-Zhejiang Rockwill Energy Technology Co., Ltd.

RH Series household ESS

A home energy storage system (ESS) is an integrated power storage solution designed to optimize home electricity management and enhance energy utilization efficiency and stability. This system mainly consists of energy storage batteries, bidirectional inverters and energy management systems (EMS). The energy storage battery is a lithium iron phosphate battery used for storing electrical energy. The bidirectional inverter is responsible for the bidirectional conversion between direct current and alternating current. The energy management system is like the "brain", intelligently regulating the storage and release of electrical energy.
During operation, the home energy storage system can flexibly adapt to various scenarios. During the day, if solar panels are installed at home, the excess electricity can be converted into direct current through an inverter and stored in the battery. At night or when there is insufficient light, the electrical energy in the battery is converted back into alternating current through the inverter for household use. In the event of a power outage in the power grid, the system can quickly switch to off-grid mode to continuously supply power to key devices such as refrigerators, lighting, and routers, ensuring that daily life is not affected. In addition, by taking advantage of the peak-valley electricity price mechanism, charging during the off-peak electricity price period and discharging during the peak period can effectively reduce electricity costs.

In terms of safety, the system is equipped with comprehensive overcharge, over-discharge and short-circuit protection mechanisms to ensure safe use.

the mian function Introduction

1. Intelligent energy management is its core highlight.

The Energy Management System (EMS) can intelligently plan the storage and release strategies of electrical energy based on household electricity consumption habits, real-time electricity prices and the power generation situation of renewable energy. For instance, photovoltaic power generation should be given priority, surplus electricity should be stored, and battery power supply should be activated when there is a power shortage to maximize energy utilization.

2. The power supply stability is strong. The home energy storage system supports free switching between grid-connected and off-grid modes.

When the power grid is normal, it supplies power in coordination to enhance the stability of electricity usage. In the event of sudden situations such as power outages and bad weather, it can respond within milliseconds and automatically switch to off-grid mode to ensure that critical loads such as refrigerators and medical equipment are not disconnected, providing a solid power guarantee for the family.

3. Significantly reduce electricity costs.

By taking advantage of the price difference between peak and off-peak hours, charge during the off-peak hours and discharge during the peak hours to reduce the consumption of high-priced electricity. If a household is equipped with solar panels, it can also store surplus electricity for its own use through an energy storage system, reducing reliance on the power grid. In the long run, this can significantly cut electricity bills.

4. No-installation design and flexible stacking solutions.

No installation required. Just connect the wires after opening the box and it's ready to use. This energy storage system adopts a modular design, allowing for the free combination of battery capacity and system scale according to the household's electricity demand.

5. Perfect protection function.

The system is equipped with a complete self-check and protection function, which can monitor parameters such as battery status, voltage and current in real time. It has overcharge, over-discharge and short-circuit protection mechanisms, reducing the risk of failure and making maintenance simple and worry-free.

6. Green environmental protection and ecological integration.

Reduce the consumption of fossil energy and lower carbon emissions by using renewable energy sources such as solar energy. In addition, in the future, home energy storage systems will be deeply integrated into the smart home ecosystem, interacting with smart home appliances, security systems, etc., to achieve a smarter, more convenient and greener home life experience
