Parameter
Description
Where to find:
Load Current
Total Load current is the sum of any analogue input
configured as Load current. Otherwise, if Battery
Current is available, the Load current is calculated as
Rectifier Current
–
Battery Current. Otherwise it is
unavailable.
Battery Current
Total Battery current is the sum of any analogue
inputs configured as Battery current. If positive
battery is being charged.
Solar Current
Total current produced by the Solar chargers
controlled by EC500.
Sum of Reported
Rectifier Currents
The sum of the currents reported by all rectifiers.
Where there is no analogue input configuration as
Rectifier current. This will be the same value as
Rectifier current.
Load Power
The power being supplied to the load. Load current x
Bus voltage.
System Power
Calculated as Bus voltage x Rectifier current if system
operating at Mains supply or DG.
Calculated as Bus voltage x Load current if system
operating at Battery bank.
Solar Power
The total power produced by the solar chargers
controlled by EC500.
AC Voltage
Single Phase System:
At the time of polling which
rectifier communicates with EC500 first time and
provides the data of AC voltage that rectifier is
determined for voltage measurement.
Three Phase System:
Similarly, at polling time which
rectifier communicates with EC500 and provide
specific phase data (R,Y or B) that rectifier is
considered for AC measurement for respective
phase.
Rectifier Delta
Temperature
Each Rectifier provides its delta, subtraction of
Rectifier Ambient temperature
–
Max Heat Sink
temperature.
Battery
Temperature
Each Battery module provided itself through
communication.
ANALOG INPUTS
The analog inputs (AI) monitor variable dc voltages (bus voltage sense, general purpose analog inputs, current
sensors or temperature sensors).
Generally, the system analog inputs are configured at the factory and do not need to be changed.
➢
To configure an analog input
•
Web go to Menu>System Config>Hardware Mapping, select Tab for analog inputs Battery,
Load, Cabinet, String Monitoring and User Analog Channels.
The table shows the available number of analog inputs. The actual number of analog inputs
available depends on the number of I/O boards or modules connected.
