Application

Residential Use

Ideal for homes in rural, suburban, or off-grid locations, the system powers essential household appliances such as lights, TVs, microwaves, refrigerators, freezers, and water pumps. It eliminates monthly electricity bills and provides peace of mind during grid failures, making it a perfect choice for eco-conscious homeowners prioritizing energy independence.

Commercial & Industrial Applications

Suits small businesses, farms, remote offices, and industrial facilities that require stable power without relying on the grid. It can handle load powers ranging from 1KW to 10KW and above, supporting daily operations, machinery, and critical equipment. Commercial users benefit from reduced operational costs and a lower carbon footprint, enhancing brand sustainability.

Specialized Scenarios

Perfect for solar energy systems in remote construction sites, mountain cabins, sailboats, and emergency shelters. Its versatile mounting options (ground, roof, carport, BIPV) adapt to diverse environments, ensuring reliable power even in challenging locations with varying sunlight conditions.

Core Features

High-Efficiency Solar Panels

Available in Monocrystalline Silicon and Polycrystalline Silicon (Grade A) options, the panels boast exceptional light-to-electricity conversion rates. The PV Array configuration allows customization to meet specific energy demands, ensuring optimal performance based on your location’s sunlight availability.

Intelligent Power Management

Equipped with MPPT and PWM charge controllers that automatically regulate battery charging—preventing overcharging or deep discharge to extend battery lifespan. The DC to AC Inverter efficiently converts stored DC power into 220/380V or 110/120/230V AC electricity, compatible with standard household and commercial appliances.

24/7 Uninterrupted Power

With reliable Lead-Acid or Lithium Ion batteries, the system stores excess energy generated during the day for use at night or during cloudy weather. Its 24-hour work time ensures continuous power supply, eliminating the inconvenience of blackouts.

Durable Mounting & Weather Resistance

Supports multiple mounting types (Ground Mounting, Roof Mounting, Carport Mounting, BIPV Mounting) to fit different installation scenarios. Engineered to withstand extreme weather: wind load up to 150 KM/H and snow load of 1.4KN/M2, ensuring long-term performance in harsh conditions.

Pre-Sales & Configuration Support

Offers professional pre-sales project design to tailor the system to your energy needs, usage patterns, and location. The distribution panel (including subpanels for critical loads) ensures safe and efficient power distribution to all connected appliances.

FAQ

How do I determine the right system size for my needs?

The system size depends on your daily electricity consumption (kWh) and your location’s average sunlight hours. Our pre-sales team will assess your energy usage (e.g., from utility bills) and local solar irradiance data to recommend the appropriate number of solar panels, battery capacity, and inverter size. For example, a 3KW system suits small homes, while 8KW-10KW systems are ideal for larger households or small businesses.

Can the system work during cloudy days or power outages?

Yes. While solar panel efficiency may decrease slightly on cloudy days, the system still generates electricity. Excess power generated on sunny days is stored in batteries, which supply power during low-light periods or grid outages. The 24-hour work time ensures uninterrupted power regardless of weather conditions.

Is professional installation required?

We strongly recommend working with a qualified installer experienced in off-grid systems. Proper configuration and installation are critical for safety, performance, and warranty validity. Our team can provide guidance on finding certified installers or offer technical support for professional setup.

What type of battery is better—Lead-Acid or Lithium Ion?

Lead-Acid batteries are cost-effective and reliable for basic needs, while Lithium Ion batteries offer higher energy density, longer lifespan, and faster charging. The choice depends on your budget, energy requirements, and maintenance preferences. Our pre-sales design team can help you select the best option for your scenario.

Can I expand the system later if my energy needs grow?

Yes. The system is designed for scalability. You can add more solar panels, batteries, or upgrade the inverter to increase capacity as your energy needs change (e.g., adding new appliances, expanding your home or business).
