Note that only professionals may install or replace DTU. Do not try to repair the DTU without approval from Solenso. If the DTU is damaged, send the DTU back to your installer for repairing/replacement. Disassembling the DTU without approval from Solenso will invalidate the remaining warranty period. -

It converts the DC output of PV modules into grid-compliant AC power. It sends the output information of PV modules and the operation data of the microinverters to the DTU, which is the hardware basis of module-level monitoring. With conversion efficiency up to 96.5% and MPPT efficiency up to 99.9%, Solenso microinverters are among the high-quality microinverters in the world. -

(input port) to cease the output of active power or limit active power to a regulated level. This logic input can be the RS485 port, Ethernet port, and so on. The DTU provides the MQTT protocol over RS485 port for this remote active power control. For more information, refer to the “MQTT Implementation Technical Note”. -

Add connection status, which displays the signal strength between each microinverter with connected DTU, so that the installer can adjust the DTU installation location accordingly. This function simplifies DTU installation and avoids a second visit for installer due to the poor connections between DTU and certain microinverters. - Page 8 Note: The initial password of the end-user account is: 123456 It can be edited by the cleints on the Personal Center of My Solenso. The newly-added site will be displayed on the station list under the Installer account. Please hold on for a while.
