The distance between your solar panel array and the inverter can impact system performance and efficiency. Here are some factors to consider when determining the best distance:

1. Voltage Drop: Longer distances can result in higher voltage drop, especially with DC systems. It’s important to calculate the voltage drop based on the distance and the wire gauge to ensure that the voltage at the inverter remains within the acceptable range.
2. Wire Gauge: Using thicker wire (lower gauge) can help reduce voltage drop over longer distances. Ensure that the wire gauge is suitable for the current carrying capacity of the system.
3. Efficiency: Shorter distances between the solar panels and the inverter can improve system efficiency, as less energy is lost during transmission.
4. Installation Considerations: Consider the ease of installation and maintenance when determining the distance. Longer distances may require more materials and labor for installation and future maintenance.
5. Inverter Location: The inverter should be installed in a location that is easily accessible for maintenance and meets any safety requirements. Consider proximity to other system components and the main electrical panel.
6. Manufacturer Recommendations: Follow the manufacturer’s recommendations for the maximum distance between the solar panels and the inverter to ensure optimal performance and warranty coverage.

In general, keeping the distance between the solar panel array and the inverter as short as feasible, while considering the above factors, is recommended for best performance and efficiency.
