Overview
•
Integrated interface
•
Where to connect: Terminal strip inside the inverter
•
3-pin wiring
•
Communication address must be allocated.
•
Multi-string technology
Pico / Convert inverters are fitted with several MPP trackers: Each string input is monitored separately and
ideally adjusted to the connected modules.
Depending on any parallel connections inside the inverter the Solar-Log™ can read the data from up to 3
individual strings.
During the inverter detection, the Solar-Log™ automatically detects how many MPP trackers are active;
only the active MPP trackers are displayed. The inverter must be feeding data in for successful detection.
•
Installation steps
