FAQs

1. What is the difference between the 4.2KW and 6.2KW models?

The 4.2KW model is designed for basic residential energy needs and essential appliance backup, while the 6.2KW model supports higher household power demand and more simultaneous appliance usage.

2. Is the 4.2KW system suitable for small homes or apartments?

Yes. The 4.2KW ESS system is ideal for small homes, apartments, cabins, and users with moderate daily electricity consumption.

3. Why choose a 6.2KW ESS system instead of 4.2KW?

The 6.2KW model provides higher output capacity, making it better suited for larger households or users who need longer backup time and support for more electrical devices.

4. Can both 4.2KW and 6.2KW systems store excess solar energy?

Yes. Both models are designed to store surplus solar energy during the day for nighttime use or emergency backup power.

5. Which model is more suitable for daily backup power applications?systems?

The 4.2KW system works well for essential household backup, while the 6.2KW system is more suitable for users who require more stable and continuous power support during outages.
