DCM-PV module

DCM-PV module

PERIPHERAL MODULE FOR MEASUREMENT OF DC SIDE QUANTITIES IN PV PLANTS

The DCM-PV module is installed upstream of the inverter to measure the DC quantities produced by the photovoltaic panels:

  • DC current from PV strings (30 A max) **
  • DC voltage from PV strings (600 V max) **
  • DC power from PV strings (18 kW max)

DCM-PV is directly connected to the DC bus coming from PV strings by mean of terminal blocks
(option: specific field connectors (i.e. MC4 type)).

DCM-PV is arranged in IP65 enclosure, with key door. It is powered directly by E2M-PV module, which is connected to via a RS485 bus over Modbus RTU protocol.

In case of multi-string inverters or plants with multiple inverters, it is necessary to install more than one DCM-PV module:
the E2M-PV recording module can manage up to 6 distinct DCM-PV modules.

** On demand, models with different current and voltage range can be assembled.

  • RS485 field bus terminal blocks with independent input and output blocks.
  • Independent overvoltage suppressors for positive and negative DC rails from PV panels.
  • Overvoltage suppressor independent for field bus.
  • Supply voltage: 12 Vdc from E2M-PV module.
  • Plastic enclosure IP65 30x35x20 cm, with door key and sealed cable glands.

** On demand, models with different current and voltage range can be assembled.
