In the context of today's energy transition, Amensolar is committed to providing users with efficient and intelligent energy solutions. The Self-Generation and Self-Consumption Mode, with its outstanding energy management capabilities, is becoming an ideal choice for many households to achieve energy self-sufficiency and cost savings.

I. Self-Generation and Self-Consumption Mode: A Revolution in Household Energy Management

The Self-Generation and Self-Consumption Mode is a power self-sufficiency model based on advanced photovoltaic (PV) technology and energy storage systems. Its core concept is to store excess electricity generated from solar energy in high-performance lithium battery energy storage systems when sunlight is abundant. During periods of insufficient sunlight or peak electricity prices, the energy storage lithium batteries release electricity to power household loads. Through this intelligent energy scheduling method, the Self-Generation and Self-Consumption Mode can significantly increase the proportion of self-generated electricity used by households, greatly enhance the self-sufficiency rate of household energy, and thereby minimize dependence on the traditional power grid, saving users a considerable amount of electricity costs.

II. The Operating Logic of the Self-Generation and Self-Consumption Mode

Under the Self-Generation and Self-Consumption Mode, the system operates according to a clear priority principle: household loads (Loads) first, then energy storage batteries (Battery), and finally the grid (Grid). Here are detailed explanations of several typical usage scenarios:

(1) Sufficient Sunlight: PV Powers Loads, Charges Batteries, and Feeds Surplus Electricity to the Grid

When the sunlight is bright and the photovoltaic power generation capacity (Ppv) is sufficient, the system first meets the power demand of household loads (Pload). After the load demand is satisfied, the surplus photovoltaic electricity is used to charge the energy storage batteries, further increasing the energy reserve of the storage units. If there is still excess photovoltaic electricity at this time, it is safely and efficiently transmitted to the grid through an inverter for optimized energy utilization. This process can be represented as:

Pgrid=Ppv−Pload−Pbattery

(2) Insufficient Sunlight: Energy Storage Batteries Provide Supplementary Power

When the sunlight is poor or at night, and the photovoltaic power generation capacity cannot meet the household load demand, the energy storage system plays a key role. The energy storage batteries release electricity to compensate for the insufficient photovoltaic power, ensuring stable power supply to household loads. At this time, the household load power is jointly provided by photovoltaic power and energy storage system power, that is:

Pload=Ppv+Pbattery

(3) No Sunlight: Energy Storage Batteries Supply Power Independently

During the night or prolonged overcast weather with no sunlight, the energy storage batteries take on the task of powering household loads independently. At this time, the household load power is entirely provided by the energy storage system power, ensuring uninterrupted household electricity use:

Pload=Pbattery

(4) Insufficient Energy Storage Battery Capacity: Grid-Assisted Power Supply

When the energy storage battery capacity is exhausted, and photovoltaic power generation cannot meet the household load demand, the system intelligently switches to grid-assisted power supply mode. At this time, the household load power is jointly provided by energy storage system power and grid power, ensuring the continuity of household electricity use:

Pload=Pbattery+Pgrid

III. Advantages of the Self-Generation and Self-Consumption Mode

The Self-Generation and Self-Consumption Mode, with its excellent energy management capabilities and significant economic benefits, provides an ideal energy solution for household users. It ensures stable and cost-effective household electricity use, whether during the sunny daytime or the dark night. Amensolar is committed to continuous innovation and optimization to provide users with more efficient and intelligent energy experiences, contributing to global energy transition and sustainable development.
