Warning:

When operating the PV strings, be aware that sunlight exposure can generate high voltages in the PV strings. Avoid contact with exposed electrical connectors 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.

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 model inverters. If exceeds, it may damage the inverter and is not covered by Deye's warranty.

3.7 Meter or CT installation

There are three selectable installation methods to measure the power consumption and to ensure zero power export to grid. The default installation method is to use the CTs (100A/50-mA) 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 100 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.

3.7.1 CT connection

*Note: When taking power from the utility grid, if the grid power displayed on the LCD screen is indeed negative, please adjust the installation direction of the CTs.

3.7.2 Meter connection without CTs

There are two kinds of smart meter, one is passthrough smart meter, and the other is Mutual inductance smart meter with CTs. The smart meter brands that Deye inverters have been matched with include CHINT and Eastron, The recommended models here are not all compatible models, It is recommended to purchase smart meter from authorized distributors of Deye, otherwise it may not be able to be used due to communication mismatch. The definition of the "Meter" port can be found in the Appendix part which is in the end of this user manual.

The LCD is touchscreen, below screen shows the overall information of the inverter.

1. The icon at the center of the screen indicates whether the system is under normal operation or not, displaying "ON" for normal status or displaying a code like "Comm./F01-F64" for communication errors or other errors. Please refer to the Error code list of alarms and errors in chapter 8 to find out solutions about the error.

2. At the top-center of the screen is the date and local time that must be set during commissioning.

3. System Setup Icon, Press this set button, you can enter into the system setup screen which including Basic Setting, Battery Setting, Grid Setting, System Work Mode, Generator Port Use, Advanced Function and Device info.

4. The main screen includes the icons for PV(left up), grid (right up), load (right bottom) and battery (left bottom). It also displays the energy flow direction by moving dots. When the power is approaching to a high level, the color on the panels will change from green to red, showing vividly the system status on the main screen.

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 from the grid (purchased).

-Negative battery power means charge, positive means discharge.

Work Mode

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.

graph LR
    A["Solar"] --> B["Battery"]
    B --> C["Backup Load"]
    C --> D["On-Grid Home Load"]
    D --> E["Grid"]

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.

Note:

Customer can only use export limit control function by CT or meter.

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 output 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.

System Work Mode

Battery Setting

System Work Mode

Time of use: it is used to program when to use grid or generator to charge the battery, and when to discharge the battery to power the load. Only tick "Time Of Use" then the follow items (Grid, charge, time, power etc.) will take effect.

Note: when in selling first mode and click time of use, the battery power can be sold into grid.

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.

For example

During 00:00-05:00,

if battery SOC is lower than 80%, it will use grid to charge the battery until battery SOC reaches 80%.

During 05:00-08:00,

if battery SOC is higher than 40%, hybrid inverter will discharge the battery until the SOC reaches 40%. At the same time, if battery SOC is lower than 40%, then grid will charge the battery SOC to 40%.

During 08:00-10:00,

if battery SOC is higher than 40%, hybrid inverter will discharge the battery until the SOC reaches 40%.

During 10:00-15:00,

If battery SOC is lower than 80%, hybrid inverter will charge the battery until the SOC reaches 80%. If the PV power is sufficient, the battery can be charged to 100%.

During 15:00-18:00,

when battery SOC is higher than 40%, hybrid inverter will discharge the battery until the SOC reaches 40%.

During 18:00-00:00,

when battery SOC is higher than 35%, hybrid inverter will discharge the battery until the SOC reaches 35%.

System Work Mode

It allows users to choose which day to execute the setting of "Time of Use".

For example, the inverter will execute the time of use page on Mon/Tue/Wed/Thu/Fri/Sat only.

Grid Setting/F(W)

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.

Reserved: This function is reserved. It is not recommended.

After setting grid parameters, please select "Lock out all changes" and enter password. If the engineer does not know the password, please contact your distributor.

GEN PORT USE

GEN PORT USE

GEN PORT USE

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. ON: 100%, OFF: 95%: When the battery bank SOC reaches 100%, Smart Load Port will switch on automatically and power the load connected. When the battery bank SOC < 95%, the Smart Load Port will switch off automatically.

Smart Load OFF Batt

- Battery SOC or voltage at which the Smart load will switch off.

Smart Load ON Batt

- Battery SOC or voltage at which the Smart load will switch on.

On Grid always on: When "on Grid always on" is checked, the smart load port will always keep switching on if hybrid inverter is 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 OFF: When the battery SOC or voltage rise to this set value and the hybrid inverter is operating in off-grid mode, the frequency of GEN port of hybrid inverter will be raised to 'AC Couple Frz High' to trip the Grid-tied inverter. It's invalid in on-grid mode.

*Micro Inv Input ON: When the battery SOC or voltage drops below this set value, the relay on GEN port of hybrid inverter will be switched on, then the Grid-Tied inverter will generate power and feed into hybrid inverter.

AC Couple Frz 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 Frz high) and the Microinverter will stop working.

MI export to Grid cutoff: Stop exporting power produced by the microinverter or Grid-Tied inverter to the grid.

*Note: Micro Inv Input OFF and On is valid for some certain FW version only.
