5). MPPT voltage range
y0.04 and y0.05 are respectively the lowest voltage and highest voltage under the MPPT mode.
Smaller the range between the two, the faster is the tracing of maximum power, but the bus voltage
during normal operation must fall within this range else the maximum power point may not be tracked.
Generally, the factory default value is OK.
6). Setting of fault point and fault delay reset time
If clients need to use the pre-warning of weak light, water-logged, under-load, failure monitoring point,
delay time and reset time, water-logged/controlled function can be set as y0.15~y0.19 on demand;
under-load function can be set as y0.20~y0.22; weak light function as y0.13~y0.14. Users can also go
for the default values.
7). Parameter setting after the system’s normal operation
When the water yield is normal, and system is running steadily, the commissioning is completed. And
then set b1.00=1, to change the terminal operation mode. Set auto reset times, E0.27=5 (as per
system requirement).
