昆山Household energy storage
Detailed:

Household energy storage is the necessary auxiliary of distributed energy system


According to the application scenario, energy storage can be divided into user side (self-use, peak-valley spread arbitrage), power generation side (renewable energy grid connection, reduce light and wind abandonment), power grid side (power peak regulation, frequency regulation), transmission and distribution side and auxiliary services (5G base station backup power source).



The core of the household light storage system is photovoltaic + battery + energy storage inverter


Household energy storage and household photovoltaic with household light storage system, the light storage system mainly includes battery, energy storage inverter (two-way converter), component system and other parts, typical system is generally 5KW (component + inverter) with 10KWH (energy storage battery) or 10KW+10KWH, in which the battery is the core of the energy storage system. The cost accounts for about 45-50%; The energy storage converter can control the charge and discharge, and carry out the AC and DC transformation, and the cost accounts for about 10-15%. The module system, that is, the photovoltaic system, is used for solar power generation, and the cost accounts for about 20-25%; Installation costs rose from 10,000 in 2021 to about 20,000, accounting for 15-20%.
