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.

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.

For example:
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 make supplement for ba�ery and load simultaneously.
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.

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＜50.2,
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 50.2Hz, the inverter will stop decreasing
output power.
For the detailed setup values, please follow the local

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.
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.

7. Fault informa�on and processing
The energy storage inverter is designed according to the grid-connected opera�on standard
and meets the safety requirements and electromagne�c compa�bility requirements. Before
leaving the factory, the inverter undergoes several rigorous tests to ensure that the inverter
can operate reliably.
1. Inverter serial number;
2. Distributor or service center of the inverter ;
3. On-grid power genera�on date;
4. The problem descrip�on (including the fault code and indicator status displayed on the LCD)
is as detailed as possible.
5. Your contact informa�on.In order to give you a clearer understanding of the inverter's fault
informa�on, we will list all possible fault codes and their descrip�ons when the inverter is not
working properly.
The 1st priority power of the system is always the PV power, then 2nd and
3rd priority power will be the ba�ery bank or grid according to the se�ngs.
The last power backup will be the Generator if it is available.
If any of the fault messages listed in Table 7-1 appear on your inverter and the
fault has not been removed a�er restar�ng, please contact your local dealer or
service center. You need to have the following informa�on ready.
