Description
Technical Field
The invention relates to the field of control of liabilities of photovoltaic energy storage and charging, in particular to system control equipment for realizing integrated integration of a household photovoltaic power generation system, an energy storage system, a charging system and a household load system.
Background
Currently, in known household photovoltaic roof power generation systems, the source of electricity consumed by the load part of the electrical appliance comes from the power grid or from solar energy respectively. And when the solar instant power generation amount is larger than the electric quantity required by the household load, the household solar power generation system sells electric power to the power grid. When the solar energy system power is less than the power required by the household loads, the power energy required by the household loads needs to be supplemented by the power grid.
Under the condition that the household daily load is preferentially ensured to use solar green power, the household energy storage system stores the residual power generated by household solar energy on the energy storage battery side, so that the household load energy demand can be conveniently supplied when the household solar energy system does not generate power at night.
With the popularization of new energy automobiles, the daily charging of the new energy automobiles greatly increases the demand of families on green energy power. Under the condition that the capacity of the photovoltaic installation at home is set, the requirement for the maximum effective utilization of new energy is more important and urgent.

The monitoring of detailed demand relation data of solar energy production power, energy storage power, household load and charging pile system at the moment in time cannot be realized. At present, the communication protocols of a photovoltaic power generation inverter platform system, an energy storage platform system and a charging pile system are all five-in-eight, are all politics, and cannot integrate different systems such as light, storage, charging, household load and the like on one platform. At present, the photovoltaic power generation inverter APP control system, the energy storage APP control system and the charging pile APP system are respectively administrative, and a terminal client cannot control a plurality of APP systems to realize control. Integration of different systems such as light + storage + charging + home load on one APP cannot be achieved. Therefore, "adjustability and customization" of new energy produced by photovoltaic cannot be utilized, and "adjustability and customization" of an energy storage system cannot be utilized, and similarly, communication and "adjustability" of a charging pile charging system and a photovoltaic power generation, energy storage and household load system cannot be realized.
