Home Energy Storage Solution

I. JOZOKING home energy storage system:

Core function: A device that stores electricity for the home, equivalent to a large “home rechargeable battery”.

Main purpose: to store electricity, when needed (such as peak electricity prices, blackouts or night) released for home use.

Common combinations: Usually used in conjunction with roof-mounted solar PV panels to form a “PV+storage” system. (also known as a “photovoltaic storage” or “solar battery” system) It can also be charged solely from the grid (especially when electricity prices are low)

II. Core Components

1.Storage Battery: The core of the system, used to store electrical energy. The mainstream technology is lithium-ion batteries (e.g. lithium iron phosphate, which is widely used for its safety and long life).

2.Inverter: The key equipment, responsible for:

l Converting the DC power generated by the photovoltaic panels into AC power available to the household.

l Converting DC power stored in batteries into AC power for home use.

l Managing the flow of electricity between the PV, the battery, the grid and the household load (in some systems the inverter is integrated with the battery).

3.Energy Management System: The brain of the system, usually software combined with a hardware controller.

l Monitors energy production (solar), consumption and battery status.

l Intelligently controls charging and discharging based on preset strategies (e.g., maximize self-consumption, save electricity, backup power).

l Users can view data and control via mobile app.

4.Others: Distribution boxes, cables, monitoring equipment, etc.

III. Key values of home energy storage systems

1. Increase the rate of solar energy self-use:

Solar-generated electricity is not used up during the day and is stored for use at night, reducing dependence on the grid and the purchase of high-priced electricity.

2. Save electricity costs (peak and valley arbitrage):

Charge from the grid during low price hours (e.g., late at night) and use stored power during peak hours (e.g., in the evening) to avoid high-priced electricity.

3. Provide backup power:

Automatically switching to battery power in the event of a grid outage to protect the operation of critical appliances (refrigerators, lighting, internet, etc.) and increase the resilience of household electricity consumption, especially important in areas prone to extreme weather or where the grid is unstable.

4. Promote energy independence:

Reduces dependence on the traditional power grid and fossil energy sources, and enhances household energy self-sufficiency.

5.Support Green:

Utilize clean solar energy more efficiently and reduce carbon emissions.

IV. How does the system work?

1. During the day (with sunlight):

Solar panels generate electricity ➜ Prioritize for real-time home use.

Excess electricity ➜ charge the storage battery.

When the battery is fully charged and there is still excess power ➜ Optionally sell to the grid (if policy permits).

2. Evening/Night (no sunlight or peak electricity prices):

Household Electricity ➜ Prioritize the use of electricity from the energy storage battery.

When the battery is low ➜ Switch to grid power automatically.

3. Grid outage:

The system is automatically disconnected from the grid (anti-islanding protection).

The storage battery supplies power to specified circuits or critical loads in the home via the inverter ➜ (standby power mode).

4. When electricity prices are low (e.g. late at night):

The system can be recharged from the grid, reserving low-priced electricity for the next day's peak hours.

Product features:

● Flexible capacity: from a few kilowatts of electricity to tens of kilowatts of electricity can be selected to meet the needs of different families.

● Modularized design: Convenient to expand the capacity as needed (e.g. adding battery modules).

● Intelligent: APP remote monitoring, AI optimized charging and discharging strategy, and smart home linkage.

● Safety Improvement: Fire prevention, explosion-proof, thermal management design is the focus (such as the use of safer lithium iron phosphate batteries, built-in fire extinguishing system).

● Simplified installation: “plug and play” design, shorten installation time and cost.
