Use Ba� V: Use Ba�ery Voltage for all the se�ngs (V).
Use Ba� %: Use Ba�ery SOC for all the se�ngs (%).
Max. A charge/discharge: Max ba�ery charge/discharge
current(0-220A for 12KW model, 0-250A for 14KW
model, 0-290A for 16KW model).
For AGM and Flooded, we recommend se�ng the max A
charge/discharge current as no more than ba�ery capacity
x 20%.
. For Lithium, we recommend Ah ba�ery size x 50% =
Charge/Discharge amps.
. For Gel, follow manufacturer' s instruc�ons.
No Ba�: �ck this item if no ba�ery is connected to the
system.
Ac�ve ba�ery: This feature will help recover a ba�ery that is over discharged by slowly charging from
the solar array or grid.
Disable Float Charge: For the lithium ba�ery with BMS communica�on, the inverter will keep the
charging voltage at the current voltage when the BMS charging current requested is 0. It is used to help
prevent ba�ery from being overcharged.

the grid. If �me of use is ac�ve, the ba�ery energy also
can be sold into grid.
The PV energy will be used to power the load and charge
the ba�ery, then the excess PV energy will flow to grid.
Power source priority for the load is as follows:
1. Solar Panels.
2. Ba�eries（when the actual ba�ery SOC is higher than
the target SOC).
3. Grid.
Zero Export To Load: Hybrid inverter will only provide power to the backup load connected. The hybrid
inverter will neither provide power to the home load nor sell power to grid, if the "solar sell" behind is not
enabled.
The built-in CT will detect current flowing back to the grid, if there is, the inverter will reduce the generate
power to only power the backup loads, smart loads and charge the ba�ery.
Zero Export To CT:
Hybrid inverter will not only provide power to the backup load connected but also give
power to the home load connected. If PV power and ba�ery power is insufficient, it will take grid energy
as supplement. The hybrid inverter will not sell power to grid, if the "solar sell" behind is not enabled. In
this mode, a external CT or smart meter must be installed. As to the installa�on method of the CT or smart
meter, please refer to the chapter 3.7 of this manual. The external CT or smart meter will detect the current
flowing back to the grid, if there is, the inverter will reduce generate power to prevent selling power to grid.
Solar Sell:
“Solar sell” is for Zero export to load or Zero export to CT: when this item is ac�ve, the PV energy
will first power the loads or charge the ba�ery, then the surplus PV energy can be sold back to grid.
Max. sell power:
Maximum power allowed to flow to grid.
Zero-export Power:
This parameter will ensure the zero-export by taking from the grid some small amount
of energy that has been set with this value. It is recommended to set it as 20-100W to ensure the hybrid
inverter won' t feed power to grid.
Energy Pa�ern:
Priority of PV power usage. When "Grid charge" is enabled, the default energy pa�ern is
"Load First", this se�ng will be invalid.
Ba� First:
PV power is firstly used to charge the ba�ery and then used to power the load. If PV power is
insufficient, grid will make supplement for ba�ery and load simultaneously.
- 36 -
Time of use: it is used to program when to use grid or
generator to charge the ba�ery, and when to discharge
the ba�ery to power the load. Only �ck "Time Of Use"
then the follow items (Grid, charge, �me, power etc.)
will take effect.
Note: when in selling first mode and click �me of use,
the ba�ery power can be sold into grid.
Grid charge: u�lize grid to charge the ba�ery in a �me
period.
Gen charge:
u�lize diesel generator to charge the ba�ery
in a �me period.
Time: real �me, range of 01:00-24:00.
Power: Max. discharge power of ba�ery allowed.
Ba�(V or SOC %): The target value of ba�ery voltage or
SOC during the current �me period. If the actual SOC or
voltage of the ba�ery is lower than this target value, the
ba�ery needs to be charged. If there is a energy source
like solar power or grid, the ba�ery will be charged; If
the actual SOC or voltage of the ba�ery is higher than
this target value, the ba�ery can discharge, and when
the solar power is not enough to power the load or the
“Selling First ”is enabled, the ba�ery will discharge.

For example, the inverter will execute the �me of use
page on Mon/Tue/Wed/Thu/Fri/Sat only.
For example
During 00:00-05:00, if ba�ery SOC is lower than 80%, it will use grid to charge the ba�ery un�l ba�ery SOC reaches 80%.
During 05:00-08:00, if ba�ery SOC is higher than 40%, hybrid inverter will discharge the ba�ery un�l the SOC reaches 40%. At
the same �me, if ba�ery SOC is lower than 40%, then grid will charge the ba�ery SOC to 40%.
During 08:00-10:00, if ba�ery SOC is higher than 40%, hybrid inverter will discharge the ba�ery un�l the SOC reaches 40%.
During 10:00-15:00, If ba�ery SOC is lower than 80%, hybrid inverter will charge the ba�ery un�l the SOC reaches 80%. If the
PV power is sufficient, the ba�ery can be charged to 100%.
During 15:00-18:00, when ba�ery SOC is higher than 40%, hybrid inverter will dischargethe ba�ery un�l the SOC reaches 40%.
During 18:00-00:00, when ba�ery SOC is higher than 35%, hybrid inverter will dischargethe ba�ery un�l the SOC reaches 35%.

V(W): It is used to adjust the inverter's ac�ve power
according to the set grid voltage.
V(Q): It is used to adjust the inverter's reac�ve power
according to the set grid voltage.
These two func�ons are used to adjust inverter's output
power (ac�ve power and reac�ve power) when grid
voltage changes.
For example: V2=110%, P2=20%. When the grid voltage reaches the 110% �mes of rated grid voltage,
inverter output power will reduce its ac�ve output power to 20% rated power.
For example: V1=90%, Q1=44%. When the grid voltage reaches the 90% �mes of rated grid voltage,
inverter output power will output 44% reac�ve output power.
For the detailed setup values, please follow the local grid code.
P(Q): It is used to adjust the inverter's reac�ve power
according to the set ac�ve power.
P(PF): It is used to adjust the inverter's PF according
to the set ac�ve power.
For the detailed setup values, please follow the local
grid code.
Lock-in/Pn 5%: When the inverter ac�ve power is less
than 5% rated power, the VQ mode will not take effect.
Lock-out/Pn 20%: If the inverter ac�ve power is
increasing from 5% to 20% rated power, the VQ mode
will take effect again.
Lock-in/Pn 50%: When the inverter output ac�ve power
is less then 50% rated power, it won't enter the P(PF)
mode.
Lock-out/Pn 50%: When the inverter output ac�ve
power is higher then 50% rated power, it will enter the
P(PF) mode.
Note : only when the grid voltage is equal to or higher
than 1.05 �mes of rated grid voltage, then the P(PF)
mode will take effect.
5.9 Generator Port Use Setup Menu
Generator input rated power: allowed Max. power from diesel
generator.
GEN connect to grid input: connect the diesel generator to the
grid input port.
Smart Load Output: Use the GEN port as an AC output port, and
the load connected to this port can be controlled on/off by the
hybrid inverter.
e.g. Power=500W, ON: 100%, OFF=95%: When the PV power
exceeds 500W, and ba�ery bank SOC reaches 100%, Smart Load
Port will switch on automa�cally and power the load connected.
When the ba�ery bank SOC < 95% or PV power < 500w, the
Smart Load Port will switch off automa�cally.

Smart Load OFF Ba�
• Ba�ery SOC at which the Smart load will switch off.
Smart Load ON Ba�
• Ba�ery SOC at which the Smart load will switch on. Besides, the PV input power should exceed the se�ng value (Power)
simultaneously and then the Smart load will switch on.
On Grid always on: When click "on Grid always on" the smart load will switch on when the grid is present.
off grid immediately off: The smart load will stop working immediately when the grid is disconnected if this item is ac�ve.
Micro Inv Input: To use the Generator input port as a AC input port of micro-inverter or other on-grid inverter.
＊Micro Inv Input OFF: When the ba�ery SOC or voltage rise to this set value and the hybrid inverter is opera�ng in off-grid
mode, the frequency of GEN port of hybrid inverter will be raised to 'AC Couple Frz High' to make the Grid-�ed inverter
trip. It's invalid in on-grid mode.
＊Micro Inv Input ON: When the ba�ery SOC or voltage drops below this set value, the relay on GEN port of hybrid inverter
will be closed, then the Grid-Tied inverter will generate power and feed into hybrid inverter.
AC Couple Fre High: If choosing“Micro Inv input”, as the ba�ery SOC reaches gradually se�ng value (OFF), During the
process, the microinverter output power will decrease linear. When the ba�ery SOC equals to the se�ng value (OFF),
the system frequency will become the se�ng value (AC couple Fre high) and the microinverter or on-grid inverter will trip
from hybrid inverter.
＊Note
: Micro Inv Input OFF and On is valid for some certain FW version only.
＊AC couple on load side
: Connec�ng the output of on-grid inverter at the load port of the hybrid inverter. In this situa�on,
the hybrid inverter will not able to show the load power correctly.
＊AC couple on grid side
: Connec�ng the output of on-grid inverter at the grid port of the hybrid inverter.
＊Note
: Some firmware versions don’t have this func�on.
Solar Arc Fault ON(Op�onal):
This feature is op�onal. A�er
enabling this func�on, the inverter will detect whether there
is a arcing fault on the PV side. If arcing occurs, the inverter
will report a fault and stop outpu�ng power.

for scheduling ac�ve power and reac�ve power.
Backup Delay:
When the grid cuts off, the inverter will output
power a�er this set �me.
For example, backup delay: 3ms. the inverter will give output
power a�er 3ms when the grid cuts off.
Note: for some old FW version, the func�on is not available.
BMS_Err_Stop:
When it is ac�ve, if the ba�ery BMS failed
to communicate with inverter, the inverter will stop working
and report fault.
Signal ISLAND MODE:
When "Single island mode" is checked
and the inverter switches from on-grid mode to off-grid mode,
the build-in NO relay on the neutral line of the Load port will
pull in automa�cally, then the neutral line of the load port will
bind to groud.
