3.5 Grid connection and backup load connection

· Before connecting to the grid, a separate AC breaker must be installed between the inverter

and the grid, and also between the backup load and the inverter.This will ensure the inverter

can be securely disconnected during maintenance and fully protected from over current.Check

the recommended values in the following tables according to local regulations in each country.

The recommended speciﬁcations for AC breakers here are based on the Max.Continuous AC

passthrough current of inverter, you can also choose the AC breaker of backup side according

to the actual total operating current of all the backup loads.

· There are three terminal blocks with "Grid" "Load"and "GEN" markings. Please do not misconnect

3.6 PV Connection

3. Make sure all the wires are securely and completely connected.

Before connecting to PV modules, please install a separately DC circuit breaker between

inverter and PV modules. It is very important for system safety and eﬃcient operation to

use appropriate cable for PV module connection.

Be sure that AC power source is disconnected before attempting to wire it to the

unit.

To avoid any malfunction, do not connect any PV modules with possible leakage

current to the inverter. For example, grounded PV modules will cause leakage

current to the inverter. When using PV modules, please ensure the PV+ & PV-

of solar panel is not connected to the system ground bar.

It is requested to use PV junction box with surge protection. Otherwise, it will

cause damage on inverter when lightning occurs on PV modules.

4. Some appliances, such as air conditioners and refrigerators, may need a time delay before

recconneting them after a power outage. This delay allows the refrigerant gas to stabilize and

prevents potential damage. Check if your appliance has a built-in time-delay function before

connecting it to our inverter. Examples of appliances that may require a delay include:

Air conditioners: Balancing refrigerant gas.

Refrigerators: Stabilizing the compressor.

Freezers: Allowing the cooling system to balance.

Heat pumps: Protecting against power ﬂuctuations.

This inverter will protect your appliances by triggering an overload fault if no time delay is

present. However, internal damage may still occur. Refer to the manufacturer's documenta-

tion for speciﬁc time-delay requirements.

Warning:

Please use its own DC power connector from the inverter accessories. Do not

interconnect the connectors of diﬀerent manufacturers. The Isc current of PV

modules should not exceed the Max.PV Isc current of this inverter. If exceeds,

it may damage the inverter and is not covered by Deye's warranty.

When operating the PV strings, be aware that sunlight exposure can generate high

voltages in the PV strings. Avoid contact with exposed electrical connecters or

terminals to prevent electrical shock or injury. For safety, it is best to operate the

PV strings at night or when PV modules are not exposed to sunlight. If daytime

operation is necessary, cover the PV modules to minimize sunlight exposure and

prevent high voltage generation. Remember to turn oﬀ the DC breaker or switch

before performing any maintenance or adjustments. Do not turn oﬀ the DC

breaker or switch when high voltage or high current is present to avoid damage or

hazards. Prioritize personal safety.

3.7 Meter or CT installation

3.7.1 CT connection

There are three selectable installation methods to measure the power consumption or to ensure zero power

export to grid. The default installation method is to use the CTs（300A/5A） that come with the packaging

box. When the distance between the AC distribution box and the hybrid inverter exceeds 10 meters, which

means that the wire length of the CT needs to exceed 10 meters, it is recommended to use a smart meter

instead of three CTs. In addition, in a parallel system, if the current to be measured is greater than 300 A, the

default three CTs also need to be replaced with smart meters or larger CTs. Please contact the Deye support

team to conﬁrm which speciﬁcation of CT or smart meter to use.

Note: For the parallel system, the lead-acid battery and 'No Batt' mode are not supported.

All inverters connected in parallel must be the same model. Please use lithium battery which

is on the "Deye Approved Battery list".

Each inverter should have its own separate battery set.

Ensure that the DIP switches of each

hybrid inverter in the parallel system

are switched to the OFF state.

Note: The idle parallel ports of the ﬁrst and last inverters

need to be plugged in with matching resistors.

Some clariﬁcations about the system status are as follows:

-PV power will always be positive.

-In single inverter system, load power will always be positive. In a parallel system, the load

power may be negative, which means that the other inverters supply power to this inverter

through the load port.

-A negative Grid power means energy being exported to the grid (sold), whereas positive means

energy being imported form the grid (purchased).

-Negative battery power means charging, positive means discharging.

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, then the excess will ﬂow to grid.

Power source priority for the load is as follows:

1. Solar Panels.

2. Batteries（when the actual battery SOC is higher than

the target SOC).

3. Grid.

Max Solar Power: the maximum DC input power allowed.

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 power ﬂowing back to the grid and will reduce the power of the inverter only to supply the

backup load and charge the battery. Load consumption=Backup load.

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 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, external CTs or

smart meter must be installed. For the installation method of CTS or smart meter, please refer to the section 3.7 .

The external CTs or smart meter will detect power ﬂowing back to the grid and will reduce the power of the inverter

only to supply the backup load, home load and charge the battery. Load consumption=Backup load+home load.

Solar Sell: "Solar sell" is selectable for Zero export to load or Zero export to CT. When activating it, the surplus of

the energy generated by the PV can be sold back to grid. When it is active, the energy generated by the PV array

will ﬁrst power the loads or charge the battery, and then export 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 Pattern: Priority of PV power usage. When "Grid charge" is enabled, the default energy pattern is "Load

First", this setting will be invalid.

Batt First: PV power is ﬁrstly used to charge the battery, and the excess power will be used to power the load. If

PV power is insuﬃcient, grid will make supplement for battery and load simultaneously.

Load First: PV power is ﬁrstly used to power the load, and the excess power will be used to charge the battery. If

PV power is insuﬃcient, Grid will provide power to load.

Grid Peak-shaving: when it is active, grid power will be limited within the set value. If the grid peak-shaving

power plus PV power plus battery power cannot meet the power consumption of the load after peak-shaving, the

grid peak-shaving will be invalid, and the power taken from the grid can exceed this set value.

Grid Charge：uses the grid to charge the battery in the selected

period of time.

Gen charge:

utilize diesel generator to charge the battery

in the

selected period of time.

Time: real time, from 0:00 to 0:00 the next day.

Note: For more ﬂexible and controllable use of batteries, it is

recommended to enable the "Time Of Use" function.When the

inverter is operating in on-grid mode and "Time Of Use" is not

enabled, the inverter can charge normally, but only discharge to

provide the inverter's self-consumption power, without discharging to

power the loads.

Power: Max. discharge power of battery allowed.

Batt(V or SOC %): The target value of battery voltage or SOC during

the current time period. If the actual SOC or voltage of the battery is

lower than the target value, the battery needs to be charged. If there

is a energy source like solar power or grid, the battery will be

charged; If the actual SOC or voltage of the battery is higher than the

target value, the battery can discharge, and when the solar power is

not enough to power the load or the "Selling First "is enabled, the

battery will discharge.

Assuming that at the end of the previous time period, the actual

battery level reaches or approaches the target value of the previous

time period.

F(W): It's used to adjust the output active power of inverter

according to the 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

51.2Hz, the inverter will decrease its active 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

grid code.

V(W): It is used to adjust the inverter's active power

according to the set grid voltage.

V(Q): It is used to adjust the inverter's reactive power

according to the set grid voltage.

These two functions are used to adjust inverter's output

power (active power and reactive power) when grid

voltage changes.

Lock-in/Pn 5%: When the inverter active power is less

than 5% rated power, the V(Q) mode will not take eﬀect.

Lock-out/Pn 20%: If the inverter active power is

increasing from 5% to 20% rated power, the V(Q) mode

will take eﬀect again.

For example: V2=110%, P2=80%. When the grid voltage reaches 110% of the rated grid voltage,

inverter will reduce its active power output to 80% of the rated power.

For example: V1=94%, Q1=44%. When the grid voltage reaches 94% of the rated grid voltage,

inverter will output reactive power that accounts for 44% of the rated power.

For the detailed setup values, please follow the local grid code.

P(Q): It is used to adjust the output reactive power of

inverter according to the set active power.

P(PF): It is used to adjust the PF of inverter according

to the set active power.

For the detailed setup values, please follow the local

grid code.

Lock-in/Pn 50%: When the output active power of

inverter is less than 50% of inverter's rated power, it

won't enter the P(PF) mode.

Lock-out/Pn 50%:When the output active power of

inverter is higher than 50% of inverter's rated power,it

will enter the P(PF) mode.

Note : only when the grid voltage is equal to or higher

than 1.05 times of the rated grid voltage, then the P(PF)

mode will take eﬀect.

LVRT/HVRT: When the voltage of the power grid reaches

the set HV or LV, the relay at the inverter grid port will

remain closed for the set time to maintain stable grid

connection without tripping.

operating in on-grid mode.

Micro Inv Input: Use the GEN port as an AC couple input port,

which can be connected with micro-inverter or other Grid-Tied

inverter.

＊Micro Inv Input ON: When the hybrid inverter operates in

oﬀ-grid mode and the SOC or voltage of battery drops to this set

value, the relays on GEN port of hybrid inverter will turn to

normally closed(ON), then the Grid-Tied inverter will generate

solar power and feed into hybrid inverter. When the hybrid inverter
