Function description in details

Smart grid-connected mode (default setting) : 4 conditions must

be met before the smart grid-connected mode is entered.

Grid-connected power is adjusted in real time according to the

solar power generation.

1: The SOC of the battery is more than 90%

On Grid Mode

2: Solar is charging

3: The grid power grid is normal and in the input range

4: Work mode switch is selected to the grid-connected mode

5 Work mode switch

Timing grid-connection mode (can be set via APP) : can set the

start time of grid-connection, grid-connection working time,

grid-connection current, SOC value.

Standby Mode

In this mode, can not work in off grid mode or on grid mode, but the battery will continue to be charged if there is solar energy.

In this mode, the system works in off-grid mode, and the AC

Explanation
When the system is in on-grid or off-grid work model,if select as “Standby”state, the system will be in standby state and need reset the work model as “Turn On” state before the system re-start work Setting between 0-23 hour and 0-59 minute. For example, set as 07:30, it means that the 1st charge period will start at 7:30

Set between 0-11 hour and 0-59 minute. For example, the setting is 01:20, it means the 1st charging period is 1 hour and 20 minutes (if the timing mode is started, but don’t want it charge,change the charge period to 00:00 directly, then 1st charge period will not work) Set between 20%-100%;for example,set as 50% it means the SOC of the 1st charge period will stop working once charging to 50%. The SOC will be compared with the charging time, whichever arrives first and which stops first. For example: SOC is set as 50%, while the charging time is set as 10 minutes and the battery is only charged to 40% in 10 minutes,the system will also stop charging after 10 minutes before SOC reaching to 50%. Another example: SOC is set as 50% and the charging time is set as 10 hours. If the battery is charged to 50% less than 5 hours,the system will also stop charging before reach the set time. (This charging here refers to the mains charging instead of solar charging.For solar charger,it will be automatically charged as long as there is solar power). Set between 1-40A. For example20.0 means the charge current of 1st charging period is 20A. (This charging here refers to the mains charging instead of solar charging.For solar charger,it will be automatically charged as long as there is solar power). Setting between 0-23 hour and 0-59 minute. For example, set as 11:00, it means that the 2nd charge period will start at 11:00. Set between 0-11 hour and 0-59 minute. For example, the setting is 00:20, it means the 2nd charging period is 0 hour and 20 minutes (if the timing mode is started, but don’t want it charge,change the charge period to 00:00 directly, then 2nd charge period will not work) Set between 20%-100%;for example,set as 70% it means the SOC of the 2nd charge period will stop working once charging to 70%. The SOC will be compared with the charging time, whichever arrives first and which stops first. For example: SOC is set as 70%, while the charging time is set as 10 minutes and the battery is only charged to 40% in 10 minutes,the system will also stop charging after 10 minutes before SOC reaching to 70%. Another example: SOC is set as 70% and the charging time is set as 10 hours. If the battery is charged to 70% less than 10 hours,the system will also stop charging before reach the set time.

(This charging here refers to the mains charging instead of solar charging.For solar charger,it will be automatically charged as long as there is solar power). Set between 1-40A. For example10.0 means the charge current of 2nd charging period is 10A. (This charging here refers to the mains charging instead of solar charging.For solar charger,it will be automatically charged as long as there is solar power). Setting between 0-23 hour and 0-59 minute. For example, set as 08:00, it means the system will discharge battery power to the grid (feed to grid) from 08:00 in 1st discharging period. Set between 0-11 hour and 0-59 minute. For example, the setting is 03:20, it means the 1st discharging period is 3 hour and 20 minutes (if the timing mode is started, but don’t want it discharge,change the discharge period to 00:00 directly, then 1st discharge period will not work) Set between 20%-100%;for example,set as 50% it means the system will stop discharge battery power to the grid (feed to grid) once the battery SOC reaches to 50% in the 1st discharge period. The SOC will be compared with the discharge time, whichever arrives first and it stops first. For example: SOC is set as 50%, while the discharging(feeding to grid) time is set as 10 minutes. When battery SOC discharges to 60%, but the discharge time already reach to 10 minutes,it will stop discharging(feeding to grid) also. Another example: SOC is set as 50% and the discharging time is set as 10 hours. If the battery is discharged to 50% less than 10 hours,the system will also stop discharging to grid before reach the set time. (This discharging/feeding to grid has nothing to do with solar power.For solar charger,it will be automatically charged as long as there is solar power). Set between 1-20A. For example20.0 means the charge current of 1st discharging period to grid is 20A. (This discharging here refers to battery power feeds to grid.For example,if it set as 20A, the battery power feeds to grid is: 26V*20A=520). Setting between 0-23 hour and 0-59 minute. For example, set as 12:00, it means the system will discharge battery power to the grid (feed to grid) from 12:00 in 2nd discharging period. Set between 0-11 hour and 0-59 minute. For example, the setting is 04:00, it means the 2nd discharging period is 4 hour(if the timing mode is started, but don’t want it

discharge,change the discharge period to 00:00 directly, then 2nd discharge period will not work). Set between 20%-100%;for example,set as 30% it means the system will stop discharge battery power to the grid (feed to grid) once the battery SOC reaches to 30% in the 2nd discharge period. The SOC will be compared with the discharge time, whichever arrives first and it stops first. For example: SOC is set as 30%, while the discharging(feeding to grid) time is set as 10 minutes. When battery SOC discharges to 50%, but the discharge time already reach to 10 minutes,it will stop discharging(feeding to grid) also. Another example: SOC is set as 30% and the discharging time is set as 10 hours. If the battery is discharged to 30% less than 10 hours,the system will also stop discharging to grid before reach the set time. (This discharging/feeding to grid has nothing to do with solar power.For solar charger,it will be automatically charged as long as there is solar power). Set between 1-20A. For example20.0 means the charge current of 2nd discharging period to grid is 20A. (This discharging here refers to battery power feeds to grid.For example,if it set as 20A, the battery power feeds to grid is: 26V*20A=520). Set based on the current time according to the format strictly 1. Intelligent grid-tied mode, this mode is recommended first to ensure that the battery is fully charged; Smart grid-tied mode (default setting): Four conditions need to be met to enter the smart grid-tied mode, and the grid-tied power is adjusted in real time according to the solar power generation. 1) Battery SOC is more than 90% 2) With solar charging 3) The grid power is normal and the voltage is within the input range 4) The mode switch is selected in grid-tied mode

2. Timed grid-tied mode: work according to the set start time, duration, SOC, and current

When you set the parameters in the APP and find that the settings are messed up, you need to restore the factory settings, you can press the ON/OFF button for 8 times, the system will restore the factory settings, and return to the default set
