FAQ

Q1: What is an off-grid solar system and how does it differ from on-grid?
A: An off-grid solar system works completely independently from the utility grid. It uses solar panels to generate electricity, stores surplus power in batteries, and supplies AC power through an inverter. It is ideal for remote areas, islands, or locations without reliable grid access. Unlike on-grid systems, it can provide uninterrupted power during blackouts but requires correctly sized battery storage for night and cloudy days.
 

Q2: What power ranges are available and how do I choose the right size?
A: We offer complete off-grid solar systems from 3kW to 30kW.

• 3-6kW: Small cabins, tiny homes or 1-2 bedroom houses (5-15kWh daily consumption)
• 6-12kW: Standard family villas (15-35kWh/day)
• 12-20kW: Large homes or small farms
• 20-30kW: Big villas, resorts, farms or workshops with heavy loads (air conditioners, water pumps, refrigerators, EV chargers, etc.) Tell us your daily electricity usage (kWh) and location, and our engineers will recommend the best configuration.

Q4: How many days of autonomy (backup) can the system provide?
A: Standard configurations offer 1-3 days of autonomy. We can customize battery capacity for 3-5 days or more depending on your location's weather and reliability requirements.
 

Q7: Is the system easy to install?
A: Yes. The system is designed for fast installation. We provide detailed English manuals, wiring diagrams, and video guidance. Professional local installers can complete most projects in 1-3 days. We also offer optional remote technical support.
 

Q8: What certifications do your systems have?
A: CE, IEC, TUV, RoHS, ISO9001, and some models have SAA, UL, or JET certification. All components meet international export standards.
 

Q9: What is the warranty period?
A:

• Solar panels: 10-12 years product warranty, 25 years linear power output
• Inverter & MPPT controller: 5 years
• Lithium batteries: 5-10 years
• Complete system support: 24/7 technical assistance.
•  

Q10: Can the system be expanded in the future?
A: Absolutely. Our modular design allows easy expansion of solar panels, batteries, and inverters. Many customers start with 5-8kW and scale up to 15-30kW later.
 

Q11: How long is the delivery time?
A: Standard configurations: 7-15 days after deposit. Customized systems: 20-35 days. We have strong production capacity and can handle urgent orders.
 

Q12: Do you support OEM/ODM and branding?
A: Yes. We welcome OEM/ODM cooperation. We can print your logo on inverters, panels, and packaging, and customize user manuals and outer carton design.
