Tiankai Home Integrated Light Storage and Charging System Solution

I. Solution Overview

With the increasing demand for household electricity and the widespread adoption of new energy vehicles, the traditional single-use electricity model is shifting towards “household energy self-generation and self-consumption.”

Tiankai’s integrated home photovoltaic-storage-charging system deeply integrates rooftop photovoltaics, home energy storage, electric vehicle charging, and a smart energy management platform. This enables collaborative management of the entire process of power generation, storage, consumption, and charging, creating a safe, intelligent, and efficient green energy center for the home.

The system can be widely applied to detached villas, self-built houses, courtyard homes, rural residences, and bed and breakfasts, helping users reduce electricity bills, increase energy self-sufficiency, and achieve a green and low-carbon lifestyle.

III. System Working Principle
Daytime:

Solar power generation prioritizes household loads. Excess electricity is stored in the energy storage battery. Any remaining surplus is sold to the grid.

Nighttime:
The energy storage system discharges, supplying household electricity and reducing grid purchases.

During power outages:
The energy storage system automatically switches to ensure power supply to critical loads. Refrigerators, lighting, and internet continue to operate.
