Work Mode
Selling First: This Mode allows hybrid inverter to sell
back any excess power produced by the solar panels to
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 and then excess energy will flow to grid.
Power source priority for the load is as follows:
1. Solar Panels.
2. Grid.
3. Ba�eries (un�l programable % discharge is reached).
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. The built-in CT will detect
power flowing back to the grid and will reduce the power of the inverter only to supply the local load 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. In this mode, a CT is needed. The installa�on
method of the CT please refer to chapter 3.6 CT Connec�on. The external CT will detect power flowing back
to the grid and will reduce the power of the inverter only to supply the local load, charge ba�ery and home
load.

Solar Sell:
“Solar sell” is for Zero export to load or Zero export to CT: when this item is ac�ve, the surplus
energy can be sold back to grid. When it is ac�ve, PV Power source priority usage is as follows: load
consump�on and charge ba�ery and feed into grid.
Max. sell power:
Allowed the maximum output power to flow to grid.
Zero-export Power:
for zero-export mode, it tells the grid output power. Recommend to set it as 20-100W
to ensure the hybrid inverter won' t feed power to grid.
Energy Pa�ern:
PV Power source priority.
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.
Load First:
PV power is firstly used to power the load and then used to charge the ba�ery. If PV power is
insufficient, Grid will provide power to load.
Max Solar Power:
allowed the maximum DC input power.
Grid Peak-shaving:
when it is ac�ve, grid output power will be limited within the set value. If the load
power exceeds the allowed value, it will take PV energy and ba�ery as supplement. If s�ll can’t meet the
load requirement, grid power will increase to meet the load needs.
- 37 -
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.
Note: when the grid is present, only the “�me of use”
is �cked, then the ba�ery will discharge. Otherwise,
the ba�ery won’t discharge even the ba�ery SOC is
full. But in the off-grid mode (when grid is not
available, inverter will work in the off-grid mode
automa�cally).
Power: Max. discharge power of ba�ery allowed.
Ba�(V or SOC %): ba�ery SOC % or voltage at when the

FW: this series inverter is able to adjust inverter output
power according to grid frequency.
Droop F: percentage of nominal power per Hz
For example, “Start freq F＞50.2Hz, Stop freq F＜51.5,
Droop F=40%PE/Hz” when the grid frequency reaches
50.2Hz, the inverter will decrease its ac�ve power at
Droop F of 40%. And then when grid system frequency
is less than 50.1Hz, the inverter will stop decreasing
output power.
For the detailed setup values, please follow the local

V(W): It is used to adjust the inverter ac�ve power
according to the set grid voltage.
V(Q): It is used to adjust the inverter reac�ve power
according to the set grid voltage.
This func�on is used to adjust inverter output power
(ac�ve power and reac�ve power) when grid voltage
changes.
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.
For example: V2=110%, P2=80%. When the grid voltage reaches the 110% �mes of rated grid voltage,
inverter output power will reduce its ac�ve output power to 80% rated power.
For example: V1=94%, Q1=44%. When the grid voltage reaches the 94% �mes of rated grid voltage,
inverter output power will output 44% reac�ve output power.
