The Transmitter HT10 is part of Hoymiles Rapid Shutdown solution. When paired with Hoymiles rapid shutdown
HRSD and powered on, HT10 sends a “permission to operate” signal to HRSD, to make PV modules connected
in series and then connect to string inverter, thus producing power.
In case of emergency, PV system would enter module-level rapid shutdown mode by simply disconnecting the
AC powerof Transmitter or using an external initiator.
