Specifically, the heating season is defined as the period from October 15 of the current year to April 15 of the following year, and the period outside the heating season is the non-heating season. In the heating season, the system can perform solar heating or solar/mains electricity mixed heating according to the light intensity. The system has four heating modes for users to choose from: ① Full-time constant temperature: perform solar/mains electricity mixed heating according to the temperature setting value (35°C) during the entire period; ② Time-sharing variable temperature: perform solar/mains electricity mixed heating according to the temperature setting value (35°C) during the set period (07:00-19:00), and automatically reduce the temperature setting value by 5°C for solar/mains electricity mixed heating outside the set period; ③ Time-sharing constant temperature: perform solar/mains electricity mixed heating according to the temperature setting value only during the set period (07:00-19:00); ④ Solar heating: perform photovoltaic heating during the entire period; The four modes can automatically select the high energy-saving mode from high to low energy-saving to save energy.

During the heating season, during the hour from 7:00 to 8:00 in the morning, when there is insufficient sunlight and the solar panels do not have sufficient power, the main control module automatically controls the complementary contactor to close the normally open contact of the complementary contactor. At this time, the energy storage battery supplies power to the electric heater via the 2P circuit breaker 11-2 → inverter → complementary contactor → AC terminal 8-1 of the main control module; when the energy storage battery provides power to the inverter, the SOC of the energy storage battery must be greater than or equal to 90%. When the SOC of the energy storage battery is less than 40%, the energy storage battery no longer discharges and stops supplying power to the inverter. At this time, the system only works in mode ①, i.e., full-time constant temperature mode; after 8 o'clock, the complementary contactor switches to the normally open contact and disconnects, the power supply mode switches to AC power supply, and the system operates normally.

In the non-heating season, there is no need to heat the electric heater. At this time, the main control module controls the emergency contactor to be energized, and the system supplies power to household appliances (the power of household appliances does not exceed 2kW).

When the city power outage occurs and the SOC of the energy storage battery is greater than 20%, the energy storage battery supplies power to the main control module in one way to avoid user data loss. The other way is connected to the emergency lighting and the household appliances on the backup socket through the inverter and emergency contactor; when the SOC of the energy storage battery is less than 20%, the energy storage battery stops supplying power to the emergency lighting and switches to the main control to charge the energy storage battery. The charging circuit supplies power to the DC-DC converter for the 5th output of the main control module. The DC-DC converter charges the energy storage battery so that the next emergency power supply is performed when the SOC of the energy storage battery is greater than or equal to 90%. The energy storage battery is not charged during the discharge process to ensure battery safety. At the same time, when the city power outage occurs, the system can continue to work because the main control module is equipped with a backup power supply, ensuring that the system always operates normally.

Specifically, the main control module collects information such as system voltage, current, ambient temperature, and temperature, current, and working status of each channel, analyzes, stores, displays, alarms, protects, and uploads the data. The collected information is transmitted to the local host via RS485, and transmitted to the cloud via 4G for data interaction. The cloud background performs data analysis and processing for mobile or WEB access and query. At the same time, it interacts with the AC/DC meter to control the action of the switch. The temperature module can detect the ambient temperature and the temperature of the electric heater, and can set the ambient temperature threshold, and communicate with the main control module via RS485.

In summary, the utility model monitors the system voltage, current, ambient temperature and status information of the channel in real time through the main control module and the temperature module, analyzes and stores each status information, automatically controls the relevant switch actions of the system, and then selects the power supply mode and heating mode of the system. The main control module can be powered by the mains, solar panels, inverters, and energy storage batteries. Several power supply modes can be switched intelligently to achieve the advantages of saving electricity for heating in winter and energy saving in summer. In the event of a sudden power outage from the mains, the battery can be used for emergency power supply, which is safe and reliable. The intelligently switched green electricity heating energy storage emergency control system not only saves electricity, but also reduces labor costs. The system automatically switches the power supply mode according to the actual situation to achieve optimal energy use, greatly improve energy utilization, and save user costs.
