Hybrid home photovoltaic+energy storage system

　　Introduction to Types of Household Energy Storage Systems

　　System Introduction

　　A hybrid photovoltaic+energy storage system generally consists of photovoltaic modules, lithium batteries, hybrid inverters, smart meters, CT, grid, grid connected loads, and off grid loads. This system can directly charge the battery through DC-DC conversion of photovoltaics, and can also achieve bidirectional DC-AC conversion for battery charging and discharging.

　　Work logic

　　During the day, photovoltaic power generation first supplies the load, then charges the battery, and finally the excess electricity can be connected to the grid; At night, the battery discharges to supply the load, and the insufficient part is supplemented by the power grid; When the power grid is cut off, photovoltaic power generation and lithium batteries only supply power to off grid loads, and the grid connected loads cannot be used. In addition, the system also supports users to set their own charging and discharging times to meet their electricity needs.

　　System characteristics

　　·The system is highly integrated, which can significantly reduce system installation time and cost

　　·Intelligent control can be achieved to meet the electricity needs of users

　　·Providing users with safe electricity protection during power outages in the power grid
