Residential photovoltaic energy storage systems can provide a steady stream of green power for families day and night. Do not worry about tiered electricity prices, save on utility bills, manage household energy intelligently, and enjoy a comfortable life with a high quality of life.

The excess electricity generated during the day is automatically stored for the night. In the event of an unexpected power outage, the system automatically switches to home backup power to ensure the normal operation of lighting, security systems, electrical appliances, floor heating, water treatment and other systems at all times. A home energy storage system is similar to a micro energy storage power plant, and its operation is not affected by the pressure of the municipal power supply. During periods of low power consumption, the home energy storage system battery can recharge itself to compensate for power spikes or outages. In addition to being used as an emergency power source, home energy storage systems can also balance electricity loads to reduce household electricity costs.

Home energy storage systems are currently divided into two types: grid-tied and off-grid home energy storage systems.

Grid-tied home energy storage system

It consists of five parts: Solar array, grid-connected inverter, BMS management system, battery pack and AC load. The system works with a hybrid power supply of photovoltaic and energy storage. When the power grid is normal, the load is powered by the photovoltaic system and the power grid. When the power grid is off, the consumer is powered jointly by the energy storage system and the photovoltaic system. The grid-connected household energy storage system is divided into three operation modes, mode 1: photovoltaic supplies energy storage, excess electricity goes to the grid; mode 2: PV supplies energy storage and some users use electricity; mode 3: PV supplies only partial energy storage.

Off-grid energy storage system for households

It is self-contained and has no electrical connection to the grid. Therefore, the whole system does not need a grid-connected inverter, and the photovoltaic inverter can meet the requirements. The off-grid residential energy storage system is divided into three operating modes: Mode 1: The photovoltaic system supplies the user's electricity storage and electricity (on sunny days); Mode 2: The photovoltaic system and energy storage batteries supply the user's electricity (on cloudy days); Mode 3: The energy storage battery supplies the user's electricity (in the evening and when it rains).

The gradual scale and popularization of household energy storage is a healthy and rational development trend for future energy demand in the world.Foxtheon Energy actively participates in the environmentally friendly development of energy technology, combines the advantages of its own technology platform with independent innovation capabilities, and provides a complete package of power supply solutions for residential energy storage systems, simplifies the circuit diagram of residential energy storage systems, reduces the construction and maintenance costs of home systems, and comprehensively improves the stability, safety and reliability of the system.
