1. Performance Parameters

Efficiency: The higher the conversion efficiency of the inverter, the less energy loss. Inverters with an efficiency of over 95% usually have better cost-effectiveness.
Output Power: Ensure that the output power of the inverter can meet your needs. If the power is too low, it may limit the overall output of the system; if the power is too high, it may lead to unnecessary waste.
Voltage Range: Check if the inverter's input and output voltage ranges are compatible with your system and grid requirements.

2. Reliability and Durability

Brand and Reputation: Choose well-known brands and products with good user reviews to improve the reliability of the inverter.
Warranty Period: A longer warranty period (such as 5-10 years) usually indicates the manufacturer's confidence in the product's quality.
MTBF (Mean Time Between Failures): The longer the MTBF, the better the product's durability.

3. Features and Functions

MPPT (Maximum Power Point Tracking): Inverters that support MPPT can improve the overall efficiency of the system.
Communication Capabilities: Inverters with remote monitoring and management functions allow for convenient system management and maintenance.
Protection Level: Inverters with a protection level of IP65 or higher can operate stably in outdoor environments.

4. Cost

Initial Cost: Is the purchase price within your budget?
Installation and Maintenance Costs: Consider the difficulty of installation and future maintenance costs.

5. Application Scenarios

Suitability: Is the inverter suitable for your intended application scenarios, such as residential PV systems or commercial PV systems?
Scalability: Is the system easy to expand, and can it adapt to future additions of PV modules?

6. Energy Efficiency and Economic Analysis

LCOE (Levelized Cost of Electricity): Calculate the LCOE of the system using the inverter, reflecting the cost per kilowatt-hour over the entire lifecycle.
ROI (Return on Investment): Evaluate the ROI after using the inverter.

7. After-Sales Service

Service Network: Does the supplier have a comprehensive after-sales service network to ensure timely repairs when equipment issues arise?
Technical Support: Does the supplier provide professional technical support to help resolve issues encountered during installation and use?
