Internet. RJ45 cable should be simultaneously matching with EnverBridge module.
5.1 Working Mode
The working modes of an Envertech EnverBridge are:
Start up
Active
Fault
Standby
The detailed working mode descriptions are as below:
Start up
Start up mode is for a newly installed EnverBridge.This startup mode must base on the
proper AC, micro-inverter, Ethernet cables connecting.
Active
When the EnverBridge is in normal operation process, this insures that the power
available from micro-inverter array is exported to the utility grid.
Fault
If the system does not operate correctly, Envertech EnverBridge will stop automatically
and enter into Disable mode.The Envertech EnverBridge system keeps detecting the
disable information, it will be in disable mode until fault release. If the inoperative
EnverBridge has been repaired and match to the electrical utility grid, the whole system
would enter operation mode after 60 seconds to 5 minutes. Be aware that only qualified
personnel should maintain the ENVERTECH Micro-Inverters.
Standby
When the EnverBridge is in operation process but keeps with low voltage and current in
micro-inverter side for a certain time.The EnverBridge manages transition from“Active”
to“Standby”. In “standby”mode, Micro- Inverters keep detecting the energy output of
each micro-inverter. When the output energy
reaches the power generation conditions, the inverter would enter into“Active”from the
“Standby” state.
• The equipment maintenance only can be carried through
by service department of Envertech, or the service centre
or professional authorized by Envertech. Maintenance
personnel should be familiar with all the warnings in this

6.1.1 Function of LCD
6.2 LCD 1602 interface
6.2.1Start-up interface

Then the network unlocking starts and on the screen of LCD “All MI LID clear” shows
on the first line and “...”on the second line, which indicates the overall network
unlocking process is taking place (as shown below).
Upon the completion of the overall network unlocking the network construction
between EnverBridge and MI starts. On the first line of the LCD 1602 screen “MI
connecting” indicates the connection to MI has started and“x MI connected” on the
second line shows how many MI units have been connected with x indicating the
numbers of MI units connected.
EnverBridge gets into monitoring working status following the starting-up of Enver-
Bridge. The monitoring information will be displayed on LCD, which includes four
parts,namely,IP address, the current power, power production and the numbers of MI
units (as shown below).
IP address shows on the first line of LCD screen. For example, 192.168.0.201 indicates
a normal network connection and 192.160.0.254 indicates an abnormal network
connection.
The figure of power efficiency which shows at the beginning of the second line
indicates the real-time power efficiency. For example,4895W.
The figure of power generation output which shows at the middle of the second line
indicates the overall amount of power generation. For example, 184KWh or 100MWh
The power generation output is calculated to the accuracy of KWh. If the output rises
up to MWh ,the number displayed is rounded off automatically. (Please refer to the
long distance or local server to get a detailed information.)
After the completion of network construction the EnverBridge start-up process
finishes and EnverBridge is in normal monitoring working status. It will take a
relatively long period of time before the monitoring interface information shows up
on the LCD screen. EnverBridge will unlock and construct the network again
automatically if there is a failure of network construction.
