Can you use Enphase micro-inverters with solar trackers?

Compatibility and Limitations

Enphase micro-inverters are compatible with select solar trackers, such as the SolarMax 2 tracker from Array Technologies or the X-Series tracker from Alion Energy. However, this compatibility is limited to specific tracker models, and users should verify compatibility before installation. Enphase typically requires a maximum of 2-3 micro-inverters per tracker row.

Installation and Commissioning

When using Enphase micro-inverters with solar trackers, it’s essential to follow the manufacturer’s guidelines for installation and commissioning. This includes ensuring proper communication between the micro-inverters and the tracker’s monitoring system. Typically, this requires connecting the micro-inverters to a single point of connection (SPC) and ensuring that the tracker’s monitoring system can communicate with the micro-inverters. Enphase recommends using a maximum of 4 rows of trackers per micro-inverter connection.

Monitoring and Performance

Enphase micro-inverters provide real-time monitoring and performance data for each panel, which can be beneficial when used with solar trackers. The Enphase Enlighten monitoring platform allows users to track performance metrics, such as energy production and panel temperatures, for each individual panel. This level of granularity can help identify performance issues and optimize system performance when used with solar trackers.
