Product overview
Photovoltaic energy storage system is a system that converts solar energy into electrical energy and stores it for emergencies. It is composed of photovoltaic modules, energy storage batteries, inverters, etc., which can achieve efficient use of solar energy and stable power supply. The photovoltaic system is used spontaneously during the period of photovoltaic power generation. When the photovoltaic power generation is greater than the user's electricity consumption, the excess power can be stored in the energy storage system, and the energy can be released through the energy storage system when the power generation period is not available or the power generation is weak. Since photovoltaics can only generate electricity normally when the sunlight is sufficient and the irradiance is sufficient, when the photovoltaic power generation is less than the user's power consumption, the energy storage device can be used for valley charging and peak discharging to supplement the instability of photovoltaic power generation.

Photovoltaic energy storage system use
The applicable scenarios of photovoltaic energy storage system include: industrial and commercial roofs, agricultural facilities, municipal and other public buildings, remote agricultural and pastoral areas and islands, office buildings, residential buildings, industrial parks, cultural centers, gymnasiums, administrative buildings, etc.
The photovoltaic energy storage system converts solar energy into direct current through photovoltaic modules, and then converts direct current into alternating current through an inverter for users to use. At the same time, the excess electrical energy will be stored in the energy storage battery for a rainy day. When power is needed, the energy storage battery will release the stored electric energy and supply it to the load.
Working principle of photovoltaic energy storage system
The photovoltaic energy storage system converts solar energy into DC electricity through photovoltaic panels, and then stores it through energy storage equipment. When electric energy needs to be used, the energy storage device releases the stored electric energy and converts it into an AC power supply network through an inverter. At the same time, the control system monitors the running status of photovoltaic panels and energy storage equipment in real time to realize the intelligent control of the whole system.
