Adopt voltage given mode; reference voltage is a fixed value, given by H00.03.
1：Max power point tracking（MPPT）
Using max power point tracking the given reference voltage, the reference voltage will not stop
changing until the system stable，the maximum power point of this searching mode is limited by range
of H00.04 and H00.05
2：Automatic MPPT
System track the maximum power point automatically, adaptive to different solar panel, can track
and get maximum power point rapidly.
No matter which reference voltage mode adopted, when bus voltage higher than reference
voltage, the target frequency will change to upper limit of PI output frequency; when bus voltage lower
than reference voltage, target frequency will change to lower limit of PI output frequency.

When H00.03 is 1, MPPT voltage will track within H00.04~H00.05, H00.05 must be larger than
H00.04, the smaller the difference between them, the narrower the tracking range, tracking will be
faster. But the voltage point of max power must fall in this range.
