Frequently Asked Questions (FAQ)
1. What can a 3 kW off grid solar system power?
A 3 kW system can typically power essential household or small business loads simultaneously, such as: LED lights, a refrigerator, a television, a water pump, fans, laptops, and small kitchen appliances. A detailed load assessment is recommended for precise sizing.
2. How long can it run without sun?
Autonomy depends on battery capacity and daily energy consumption. With the standard 5.12kWh battery bank and moderate use (e.g., 8-10 kWh per day), it can typically provide power through one to two cloudy days. Larger battery banks can be specified for longer autonomy.
3. Is professional installation required?
While the system is designed for straightforward installation, we strongly recommend using a qualified local electrician or solar installer. They ensure compliance with local electrical codes, optimal placement, and safe, reliable operation.
4. What is the difference between Gel and Lithium (LiFePO4) batteries?
Gel batteries are a proven, cost-effective lead-acid technology. Lithium (LiFePO4) batteries are lighter, have a longer lifespan, allow deeper daily discharge (increasing usable capacity), and charge faster, but come at a higher initial cost. The choice depends on budget and performance priorities.
5. Do you provide warranties and documentation?
Yes. All major components come with their manufacturer's warranties (typically 10-25 years for panels, 5 years for inverters). We provide full product datasheets, user manuals, wiring diagrams, and certificates of compliance for seamless import and installation.
