code
After modifying parameters 2,3,4,5,6,7,8 and 13 in the table
above, the next operation cannot be performed until the
inverter is reset.
NOTE
Under-voltage fault code caused by insufcient solar radiation
is not recorded.
Too Dark and Low voltage protection fault codes caused by
insufcient solar radiation will not be recorded.
NOTE
The control parameter of the inverter must be changed with
caution, else the system will malfunction.
NOTE
Scope
Record the last 4 fault codes. It will only display the
Read Only
first six characters of the fault code here for
d e s c r i p t i o n s s e e c h a p t e r 4 .
Start delay time in seconds after power on or
1-6000
shutdown.
Once the output frequency is less than the weak
light frequency (set value of Pr.14) and
continuously last for a period (this set value)
1-6000
inverter will enter weak light protection and report
Too dark. Unit: s
The Restart delay time after system enters weak
light protection.
1-6000
Unit: s
Water level signal detection effective delay time. If
water level signal has no change within the time
set by this value, it is a valid water level signal,
0-6000
otherwise the time will be cleared to re-
accumulate. Unit: s
The delay time after water level return normal from
source low protection.
If countdown time is more than 999 seconds, the
1-30000
screen will still show 999 with the numbers
blinking.
Unit: s
The delay time after water level return normal from
tank full protection.
If countdown time is more than 999 seconds, the
1-30000
screen will still show 999 with the numbers
blinking.
Unit: s
