Parameter
Description
Where to find:
Current Limit
Maximum current limit for solar charger.
Solar chargers cannot generate current
more than this limit.
Over Voltage
Maximum voltage limit for solar charger.
Solar charger cannot generate voltage
more than this limit.
Under Voltage
Voltage threshold. If solar rectifiers
generated voltage is less than this limit
then switch to AC from solar.
Low Solar
Current Thd.
Current threshold. If solar rectifier output
current is less than this limit, then switch
to AC from solar.
Low Solar current
time
When solar current is less than Low Solar
Current Threshold for this time limit,
generate the Low Solar current Alarm.
Load Priority Diff
voltage
This voltage defines the difference
between Solar charger voltage and AC
Rectifier voltage. AC rectifiers generate
less voltage comparatively solar rectifier
with keeping this voltage difference.
Input cut-off
High Voltage
:
When Solar charger input
voltage is more than this limit, switch
from solar to AC mode.
Low Voltage
:
When Solar charger input
voltage is less than this limit, switch from
solar to AC mode.
ID De-Register
All
:
De-register all Solar chargers with
EC500.
Individual
:
De-register individual Solar
charger with EC500.
Need to use LSS command if again
registration is required.
Redundancy
After enabling this function, the first solar
charger will activate, and the second
charger will go into sleep mode. If the first
solar charger fails for any reason, then the
second solar charger will come out of
sleep mode.
Alarm setting
Enable Solar charger alarms (S-Charger
Fail, S-Charger Comm Fail, Low Solar
Current) with severity.
