Sunchees 20kW Off-Grid Solar Power System: Best Application Scenarios and Reasons

1. Small and Medium Businesses

Application Scenarios:

• Small factories, workshops, textile mills

• Supermarkets, chain stores, restaurants

• Office buildings, warehouses, logistics centers

• Parking lot lighting and EV charging stations

Why It Is Suitable:

• Power matching: The 20kW system can support multiple devices such as air conditioning, refrigeration, lighting, and office equipment.

• Energy independence: Ideal for areas with unstable grids or frequent outages (e.g., Nigeria, Southeast Asia).

• UPS function: Ensures critical equipment like cold storage and servers remain operational without interruption.

• ROI advantage: High commercial electricity costs allow for investment payback in 3–5 years.

2. Luxury Homes and Villas

Application Scenarios:

• Luxury villas, large residences, rural vacation homes

• Community shared facilities such as swimming pools, gyms, and lighting

Why It Is Suitable:

• Whole-house power capability: Supports high-load appliances like air conditioners, refrigerators, washing machines, and pool pumps.

• Night-time power supply: Equipped with a large-capacity LiFePO4 battery (108kWh) for stable power after sunset.

• Off-grid capability: Ideal for remote villas or new residential areas where grid connection is costly.

• Green lifestyle: Increases property value and creates a zero-carbon living environment.

3. Farms and Rural Areas

Application Scenarios:

• Farm irrigation systems

• Livestock ventilation, lighting, and cold chain storage

• Power supply for greenhouses

• Mini-grids for remote villages

Why It Is Suitable:

• Solves “no grid” problems: Supports fully off-grid operation, replacing diesel generators and saving on fuel costs.

• 24-hour power: Large battery storage ensures continuous electricity for night-time needs such as surveillance and refrigeration.

• Lower maintenance costs: Solar systems are simpler to maintain than generators, with no fuel or noise issues.

• Modular installation: Adaptable for fields, sloped roofs, and mobile power stations.

4. Remote and Disaster-Prone Areas

Application Scenarios:

• Mountain clinics, schools, and small communities

• Emergency relief and post-disaster power restoration

• Islands and eco-tourism campsites

Why It Is Suitable:

• Complete energy independence: Operates without relying on grid power and can be rapidly deployed as emergency power.

• Easy transport and installation: Modular design is ideal for remote or challenging locations.

• Durability: TUV and CE certified, with robust systems resistant to wind and corrosion for harsh environments.

Summary: Why Choose the 20kW System Instead of the 50kW System?

• Suitable for small to medium loads (daily usage of 10–15kWh, peak load not exceeding 20kW)

• Ideal for users with limited budget or installation space

• Large battery capacity supports night-time operation without concern for load fluctuations

• For large factories or high-demand commercial users, the 50kW system is recommended

How does the off grid solar power system work:

• This system not only has solar power system function,but also has city grid complement function and UPS function
• At daytime,the solar panels will generate the electricity to charge the battery bank through solar charge controller and the inverter will convert battery DC power into AC power and take the loads.
• At nighttime,with fully charged battery bank,the inverter will convert battery DC power into AC power and take the loads
• When there is no sunshine and battery power is used out,the inverter will automatically switch to use city grid power and take the loads

Advantage:

• 100%green energy，no pollution，no noise
• High efficiency solar panel with 25 years lifespan can guarantee fast cost-recovery and long-term benefit
• Stand-alone system,easy installation and operation
• Nice after-sale service,provide installation guide and technical support
