How to Chose Solar inverter

When choosing a solar inverter, you need to consider the following key factors:

1. System type

Grid-connected system: Choose a grid-connected inverter to input solar power into the grid.

Off-grid system: Choose an off-grid inverter, usually used in conjunction with a battery.

Hybrid system: Choose a hybrid inverter that supports both grid-connected and off-grid operation.

2. Power matching

The rated power of the inverter should be slightly greater than the total power of the solar panel, usually 1.1 to 1.2 times.

3. Input voltage range

Make sure the input voltage range of the inverter matches the output voltage of the solar panel.

4. Efficiency

Choose a high-efficiency inverter (usually above 95%) to reduce energy loss.

5. MPPT (maximum power point tracking)

Choose an inverter with MPPT function to optimize the output of the solar panel.

6. Protection level

Choose the appropriate protection level (IP level) according to the installation environment. IP65 or higher is required for outdoor installation.

7. Brand and warranty

Choose a well-known brand, the warranty period is usually 5 to 10 years.

8. Monitoring function

Choose an inverter that supports remote monitoring, so that you can view the system status in real time.

9. Cost

Choose a product with high cost performance while meeting the needs.

10. Installation and maintenance

Choose an inverter that is easy to install and maintain to reduce later costs.

11. Certification and standards

Make sure the inverter meets local electrical and safety standards.

12. After-sales service

Choose a brand with perfect after-sales service to ensure timely technical support.

13. Scalability

If the system may be expanded in the future, choose an inverter that supports expansion.

Summary

Consider the system type, power, efficiency, protection level, brand, cost and other factors comprehensively, and choose the most suitable inverter.
