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.
