Standard RS485 over MODBUS protocol. Features
such as digital/ analog inputs, diode/ fuse protection,
high voltage protection are all included.
PV COMBI CON is compatible with any standard
These String Monitoring boxes
can be customized as per the
user requirements both in terms
of mechanical layout and
PV COMBI‐CON is compatible with any standard
power supply that the user can provide for powering
up the control circuit. Surge protection is provided
both for strings and power supply. Suitable isolator/
MCCB is provided at the output to isolate the string
