Connect DTSU666-H to SUN2000 50-60KTL-M0 inverter via FusionSolar App
This document describes how to connect Smart Power Sensor DTSU666-H to SUN2000 50/60KTL-M0 inverters with Fusion Solar App.
Prerequisites
When there are strong electromagnetic disturbances, which may affect communication, a shielded cable (with two twisted signal conductors) should be used. The terminal resistances (RT=120...150Ω) must be installed on the converter side and on the last instrument connected along the line. Thanks to these resistances, the reflected signal along the line are reduced. However, in case of short distances (max 100 m) or low communication speed (bps), there is no need of resistances.
Step 1
Connect the DTSU666-H to SUN2000 50/60KTL-M0.
