* Professional personnel can use pins 11 and 12 to realize data acquisition and external
control functions. The communication protocol is Modbus RTU. For details, please contact
us.
* If customers want to use the inverter dry contact to control external equipment (such as
a heat pump), it can be used with our Adapter Box.
* Only DRM 0/1/5 are available, others are under development.
* The inverter can be shut down through DRM0.
