The rooftop photovoltaic energy storage power supply is an integrated green power system combining rooftop solar power generation and intelligent energy storage, which converts clean solar energy into usable electricity and stores redundant power efficiently. Designed for rooftop installation scenarios of urban and rural residential buildings, the equipment features an IP55 high-level waterproof and dustproof rating, adapting to complex outdoor environments such as wind, rain, and high temperature. It adopts a lightweight and streamlined structural design, which does not damage the building roof structure or increase excessive building load, ensuring safe and standardized installation for various residential rooftops.

This photovoltaic energy storage power supply realizes the closed-loop operation of “solar power generation, energy storage, and self-use”. High-efficiency photovoltaic panels capture solar energy during the daytime and convert it into electric energy for real-time household consumption. The unconsumed electricity is automatically stored in the matched high-density energy storage battery module, avoiding the waste of clean energy. Different from traditional grid-dependent power consumption, this system greatly improves the self-sufficiency rate of household clean energy, effectively reducing reliance on municipal grid power and cutting long-term household electricity expenditure. For areas with unstable grid power supply, it can effectively make up for the shortcomings of frequent power cuts and voltage instability.

Integrated with intelligent MPPT maximum power point tracking technology, the power supply system can automatically adjust the power generation and charging state according to real-time sunlight intensity, maximizing solar energy utilization efficiency. The built-in intelligent monitoring system supports real-time viewing of power generation volume, storage capacity, electricity consumption data, and equipment operating status through mobile terminals. It has multiple safety protection functions including overcharge, overdischarge, overvoltage, overcurrent, and short-circuit protection, as well as lightning protection design, which can effectively avoid equipment failure and safety accidents caused by extreme weather and abnormal power supply. With low operation and maintenance costs and a service life of more than 10 years, it is a cost-effective long-term green power solution for household energy conservation and emission reduction.
