01
AC output source
priority
UTI default
Utility Priority. Utility power is given priority to the
loads, the battery inverts to provide power to the load
only when utility power is unavailable.
SBU
Prioritises the use of PV to power the load and
switches back to the mains to power the load only
when the battery voltage is lower than the set value in
parameter item [4] (when connected to the BMS,
according to item [61]). When the battery voltage is
higher than the value set in parameter [5] (when
connected to the BMS, according to item [62]), it
switches back to the PV from the mains to supply the
load.
SOL
PV priority. Switching to mains to power the load when
PV is not effective or when the battery is below the
setting of parameter item [4].
02
AC output frequency
50.0 default
In mains mode the AC output frequency will adapt to
the mains frequency, otherwise the output will follow
the preset values.
60.0
04
Voltage point of battery
switch to utility
43.6 default
When parameter [01]= SBU/SOL, output source will
switch to utility from battery when the battery voltage
below the preset value. Setting
range:40~52V.
05
Voltage point of utility
switch to battery
56.8 default
When parameter [01]=SBU/SOL, output source will
switch to battery from utility when the battery voltage
above the preset value. Range:48~60V.
06
Battery charging mode
SNU default
Solar and utility charging the battery at the same time,
solar at the first priority, utility power as a supplement
when solar power is not sufficient. When solar power
