Selling First: This Mode allows hybrid inverter to sell
back any excess power produced by the solar panels to
the grid. If time of use is active, the battery energy also
can be sold into grid.
The PV energy will be used to power the load and charge
the battery and then excess energy will flow to grid.
Power source priority for the load is as follows:
1. Solar Panels.
2. Grid.
3. Batteries (until 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 battery.
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 battery power is insucient, it will take grid energy
as supplement. The hybrid inverter will not sell power to grid. In this mode, a CT is needed. The installation
method of the CT please refer to chapter 3.6 CT Connection. 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 battery and home
load.

For example:
Solar Sell:
“Solar sell” is for Zero export to load or Zero export to CT: when this item is active, the surplus
energy can be sold back to grid. When it is active, PV Power source priority usage is as follows: load
consumption and charge battery 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 Pattern:
PV Power source priority.
Batt First:
PV power is firstly used to charge the battery and then used to power the load. If PV power is
insucient, grid will make supplement for battery and load simultaneously.
Load First:
PV power is firstly used to power the load and then used to charge the battery. If PV power is
insucient, grid will make supplement for battery and load simultaneously.
Max Solar Power:
allowed the maximum DC input power.
Grid Peak-shaving:
when it is active, grid output power will be limited within the set value. If the load
power exceeds the allowed value, it will take PV energy and battery as supplement. If still can’t meet the
load requirement, grid power will increase to meet the load needs.
5.8 Grid Setup Menu
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 active 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
grid code.

V(W): It is used to adjust the inverter active power
according to the set grid voltage.
V(Q): It is used to adjust the inverter reactive power
according to the set grid voltage.
This function is used to adjust inverter output power
(active power and reactive power) when grid voltage
changes.
For example: V2=110%, P2=20%. When the grid voltage reaches the 110% times of rated grid voltage,
inverter output power will reduce its active output power to 20% rated power.
For example: V1=90%, Q1=44%. When the grid voltage reaches the 90% times of rated grid voltage,
inverter output power will output 44% reactive output power.

＊Micro Inv Input ON: when the battery SOC is lower than setting value, Microinveter or grid-tied inverter will start to
work.
AC Couple Fre High: If choosing“Micro Inv input”, as the battery SOC reaches gradually setting value (OFF), During the
process, the microinverter output power will decrease linear. When the battery SOC equals to the setting value (OFF),
the system frequency will become the setting value (AC couple Fre high) and the Microinverter will stop working.
Stop exporting power produced by the microinverter to the grid.
＊
Note
: Micro Inv Input OFF and On is valid for some certain FW version only.
＊AC couple on load side
: connecting the output of on-grid inverter at the load port of the hybrid inverter. In this
situation, the hybrid inverter will not able to show the load power correctly.
＊AC couple on grid side
: this function is reserved.
＊Note
: Some firmware versions don’t have this function.

The energy storage inverter is designed according to the grid-connected operation standard
and meets the safety requirements and electromagnetic compatibility 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 generation date;
4. The problem description (including the fault code and indicator status displayed on the LCD)
is as detailed as possible.
5. Your contact information.In order to give you a clearer understanding of the inverter's fault
information, we will list all possible fault codes and their descriptions when the inverter is not
working properly.
