5.7 System Work Mode Setup Menu

System Work Mode Setup Menu

Work Mode
Selling First: This Mode allows the hybrid inverters to sell back any excess power produced by the solar panels to the grid. If the time of use is active, the battery energy also can be sold into the grid.
The PV energy will be used to power the load and charge the battery and then excess energy will flow to the 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: The 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 the 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 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 are insufficient, it will take grid energy
as a supplement. The hybrid inverter will not sell power to the grid. In this mode, a CT is needed. For 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, and charge the battery and home load.

Installation of Hybrid Inverter DEYE - Page 2

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 the grid. When it is active, PV Power source priority usage is as follows: load consumption and charge the battery and feed into the grid.
Max. sell power: Allowed the maximum output power to flow to the grid.
Zero-export Power: for zero-export mode, it tells the grid output power. Recommend setting it as 20-100W to ensure the hybrid inverter won‘t feed power to the 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 insufficient, the grid will make a supplement 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 insufficient, Grid will provide power to load.
Max Solar Power: allowed the maximum DC input power.
Grid Peak-shaving: when it is active, the grid output power will be limited within the set value. If the load power exceeds the allowed value, it will take PV energy and a battery as a supplement. If still can’t meet the load requirement, grid power will increase to meet the load needs.

System Work Mode - Time of use 1

Time of use: it is used to program when to use a grid or generator to charge the battery, and when to discharge the battery to power the load. Only tick “Time Of Use” and then the following items (Grid, charge, time, power, etc.) will take effect.
Note: when in selling the first mode and clicking time of use, the battery power can be sold into the grid.

System Work Mode - Time of use 2

Grid charge: utilize the grid to charge the battery in a time period.
Gen charge: utilize a diesel generator to charge the battery in a time period.
Time: real-time, range of 01:00-24:00.
Note: when the grid is present, only the “time of use” is ticked, then the battery will discharge. Otherwise, the battery won’t discharge even if the battery SOC is full. But in the off-grid mode (when the grid is not available, the inverter will work in the off-grid mode automatically).
Power: Max. discharge power of battery allowed.
Batt (V or SOC %): battery SOC % or voltage at when the action is to happen.

System Work Mode - Time of use 3

For example
During 01:00-05:00,
if the battery SOC is lower than 80%, it will use the grid to charge the battery until the battery SOC reaches 80%.
During 05:00-08:00,
if the battery SOC is higher than 40%, the hybrid inverter will discharge the battery until the SOC reaches 40%. At the same time, if the battery SOC is lower than 40%, then the grid will charge the battery SOC to 40%.
During 08:00-10:00,
if the battery SOC is higher than 40%, the hybrid inverter will discharge the battery until the SOC reaches 40%.
During 10:00-15:00,
when the battery SOC is higher than 80%, the hybrid inverter will discharge the battery until the SOC reaches 80%.
During 15:00-18:00,
when the battery SOC is higher than 40%, the hybrid inverter will discharge
the battery until the SOC reaches 40%.
During 18:00-01:00,
when battery SOC is higher than 35%, the hybrid inverter will discharge
the battery until the SOC reaches 35%.

Grid Setting

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 active power at Droop F of 40%. And then when the 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.

Grid Setting 2

Lock-in/Pn 5%: When the inverter active power is less than 5% rated power, the VQ mode will not take effect.
Lock-out/Pn 20%: If the inverter active 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 110% times of rated grid voltage, the inverter output power will reduce its active output power to 80% rated power.
For example: V1=94%, Q1=44%. When the grid voltage reaches 94% times of rated grid voltage, the inverter output power will output 44% reactive output power.
For the detailed setup values, please follow the local grid code.

Grid Setting 3

Lock-out/Pn 50%: When the inverter output active power is higher than 50% 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 rated grid voltage, then the P(PF) mode will take effect.

On Grid always on: When click “on Grid always on” the smart load will switch on when the grid is present.
Micro lnv Input: To use the Generator input port as a micro-inverter on grid inverter input (AC coupled), this feature will also work with “Grid-Tied” inverters.

* Micro lnv Input OFF: when the battery SOC exceeds setting value, Microinveter or grid-tied inverter will shut down.
* Micro lnv Input ON: when the battery SOC is lower than setting value, Microinveter or grid-tied inverter will start to work.

AC Couple Frz High: If choosing”Micro lnv 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.
Ml export to grid cutsoff: Stop exporting power produced by the microinverter to the grid.

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