*Tips
：
In fact, the application of the product is closely associated with solar sell and
environment. only you correctly preset the parameters of solar cell and additional use of the
parameters (“F0.02 and F0.04” ) the highest utilization efficiency can be achieved.
1. Firstly, according to the solar sell panel to preset the parameters F0.05 and “F0.06”. If
you don’t want to use the terminals “ S1~S4 ”,“S1 and S2
”
must be connected to“COM”,
otherwise it doesn’t work normally.
2. Secondary, presetting the lower frequency limit “F0.02” of ensuring that the pump can
work in this frequency.
3. After having the lower frequency limit, you need to appropriately regulation the
start-up voltage. Under the normal condition of sun light, if it starts and stops frequently, you
should properly increase the start-up voltage, of course, you also can properly reduce the value
of the lower frequency limit.
According to the environment as well as in combination with proper these two parameters
can use solar energy more efficiency.
