2: MPPT mode
Bus voltage is given as the maximum power search result, F0.03 is set to 8, photovoltaicmode.
When starting but before the searching, the bus voltage is given as E0.01, atintervals after the
search, the search result is as given value
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
thebus voltage, the inverter may run at around 0Hz during starting.
Voltage setting default value(V)
MPPT Voltage search interval time
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
When using the sleep function, set F6.13 = 1 (valid).
During the operation of the inverter, when the running frequency is less than E0.09 sleep
frequency, after the E0.11 sleep delay time, the inverter enters the sleep state and decelerates to
stop.
If the Solar inverter dormant, run command valid, after E0.03 awakens the delay time,
frequency converter to start.
Upper limit of MPPT search voltage
MPPT maximum voltage in the process of search value.
Search lower limit of voltage default(V)
Lower limit of MPPT
search voltage
Search value of lower limit voltage in MPPT search process.
Search lower limit of voltage default(V)
PID Maximum voltage deviation value
When Photovoltaic mode works, by changing parameters, can limit given bus voltage and
current bus voltage’s PID maximum input voltage deviation value
When inverter into hibernation, if the bus voltage gradually higher than the set voltage(E0.07),
the inverter will start automatically.
Wake-up voltage default Value(V)
