Off-grid Residential ESS Project


Project Description

The Residential ESS Project is a PV ESS that utilizes LFP batteries and is equipped with a customized BMS. It offers a high cycle count, long service life, and is suitable for daily charge and discharge applications. The system comprises 12 PV panels arranged in 2 parallel and 6 series configurations, along with two 5kW/15kWh PV ESS sets. With a daily power generation capacity of 18.4kWh, the system can efficiently power appliances such as air conditioners, refrigerators, and computers on a daily basis.


This innovative system integrates four key components

Solar PV components: These components convert solar energy into DC power.

Solar PV stent: It fixes and protects the solar PV components, ensuring their stability and longevity.

Inverter: The inverter controls the conversion of AC and DC power and manages the charge and discharge of the battery.

Energy storage battery: This battery stores the DC power generated by the solar panels, providing a reliable source of power at night or during periods of low sunlight.

Data monitor system: The data monitor system collects and monitors data from the energy storage system, sending it to the cloud. This allows you to easily check the status of your system anytime, anywhere.

How Dose It Work

During the daytime, the solar PV components harness the abundant solar energy and efficiently convert it into DC power. This clean and renewable power is then intelligently stored in the energy storage battery, ensuring that no energy goes to waste.

When the sun sets or during periods of low sunlight, such as cloudy, snowy, or rainy days, the stored energy in the battery seamlessly kicks in. This allows you to continue enjoying a reliable and uninterrupted power supply for your home. By utilizing the stored energy, you can confidently power your appliances, lighting, and other electrical devices, even when the sun is not shining brightly.

This smart energy management system not only provides you with a sustainable and eco-friendly solution but also offers peace of mind knowing that you have a backup power source readily available whenever needed. Embrace the benefits of solar energy and experience the convenience of uninterrupted electricity throughout the day and night.
