Do you know how solar systems generate electricity?
The core principle of solar power generation systems is a delicate energy conversion chain: photons → electrons → electric current.
Direct current (DC) cannot be directly used by household appliances and the power grid; it must be converted and intelligently managed.
The low-voltage DC power generated by solar panels is collected by an inverter. The inverter is the "heart" of the system; it uses high-speed electronic switches (such as IGBTs) to "oscillate" the smooth DC power into sinusoidal alternating current (AC) with the same frequency, phase, and voltage as the power grid (e.g., 220V/50Hz).
This process (DC→AC) is called "inversion."
On Grid Solar System: The inverter directly supplies electricity to households, uploading excess power to the grid and downloading from the grid when needed.
Hybrid Solar System: In addition to grid-connected systems, it adds batteries. Energy is prioritized for storage, achieving higher self-consumption rates and backup power during power outages.
Off Grid Solar System: All energy is stored in batteries and supplied to loads via an off-grid inverter, completely independent of the power grid.
Maximum Power Point Tracking (MPPT): The inverter's MPPT technology adjusts the operating voltage in real time to ensure the solar panels output maximum power under any lighting conditions.
Grid Connection Protection: The system constantly monitors the grid status. In the event of a grid outage, it automatically disconnects the connection (anti-islanding effect) to ensure the safety of maintenance personnel. During this time, the hybrid/off-grid system can continue to be powered by batteries.
