Off-grid domestic solar power generation systems (including hybrid photovoltaic-storage systems) are standalone clean energy solutions that integrate high-efficiency photovoltaic modules, high-capacity storage batteries, high-performance inverters, smart controllers and associated accessories. At their core, these systems convert solar energy into direct current (DC) via photovoltaic modules, which is then converted by the inverter into domestic / industrial-grade alternating current. Surplus energy is stored in the accompanying lithium-ion batteries, providing a stable power supply to electrical appliances at night, on overcast or rainy days, or in areas without grid coverage, thereby enabling self-sufficient power generation without reliance on the public grid.

The key advantage of this off-grid domestic solar system is that it provides self-sufficient power without the need to connect to the public grid. It is ideally suited to remote mountainous areas, regions without grid coverage, outdoor campsites, island villas and self-built rural homes, completely freeing users from the constraints and hassles of traditional grid-based power supply and solving the problem of accessing electricity in off-grid areas.

The system utilises industry-leading high-efficiency half-cell photovoltaic modules. Compared to traditional full-cell modules, half-cell technology significantly reduces power generation losses caused by shading whilst enhancing low-light performance, ensuring high efficiency even at dawn, dusk or in cloudy conditions. The photovoltaic modules feature high-transmittance tempered glass, premium EVA encapsulant and anti-oxidation frames, offering excellent resistance to wind, hail, anti-ageing and anti-corrosion properties.

The complete off-grid solar system is equipped with a comprehensive multi-layered safety protection system, with all core components featuring dedicated protection functions to ensure the safe operation of the system and the safety of users' electricity supply. The photovoltaic modules feature reverse connection protection, overvoltage protection and overcurrent protection to prevent circuit faults during installation and operation; the inverter integrates multiple protective functions, including over-temperature protection, overvoltage protection, undervoltage protection, short-circuit protection, islanding protection and surge protection, enabling it to rapidly cut off the power supply in the event of grid fluctuations, sudden changes in load or equipment failure, thereby preventing safety incidents.

This off-grid solar system adopts a modular, scalable design philosophy, allowing for flexible customisation based on the user's electricity load, installation space and sunlight conditions. Its power output ranges from small-scale domestic systems to complete commercial and industrial systems of 15kW–200kW, making it suitable for a wide variety of applications including domestic electricity consumption, small factories, commercial premises, outdoor base stations and agricultural irrigation. Users can select the appropriate photovoltaic module capacity, battery storage capacity and inverter power output to suit their specific requirements. The system can be expanded at a later stage as needed, allowing for the gradual addition of photovoltaic panels and batteries without the need to replace the entire system, thereby significantly enhancing the system's adaptability and flexibility.
