☆
When set E0.00 to 1, this voltage is CVT mode bus voltage set value;
When set E0.00 to 2, the voltage is the bus voltage given value when MPPT mode be
started, and also the initial value when search voltage.
Appropriate adjustments according to the site conditions.
Note: the set value should be lower than the bus voltage value, if the value is higher than
the bus voltage, the inverter may run at around 0Hz during starting.

MPPT Interval search time when set E0.00 to 2. It indicates the speed of MPPT
tracking ,lower numbers equate to better speed on MPPT tracking，but the MPPT
serching interval is short,may result in more fluctuations on output frequency of the
inverter.
