CAUTION – Electrical shock hazard. Always wear the appropriate PPE when energizing the EI Residential System components.
Prerequisites:
The EI Battery, EI Inverter, EI ATS, and Smart Meter are installed and electrically connected as per the installation manual.
Note:
If you do not have access to the customer’s WiFi, then you must perform the manual bypass procedure in Section 3.6.
1.
Turn on the EI Battery DC switch.
2.
Turn on the EI Inverter DC Disconnect switch at the bottom of the inverter.
3.
Verify that the Rapid Shutdown Initiator is in the depressed (out) position.
4.
Turn on the inverter the white circuit breaker inside ATS.
5.
Turn on the internal EI ATS 200A main circuit breaker and all OCP and disconnect switches on the grid side.
6.
If the inverter does not on, please follow the battery force start procedure below to turn it on.
7.
Open the EI App and begin the commissioning process.
Note:
- The “battery” light on the ATS will turn solid green when the inverter detects the grid.
8.
Contact Tigo
Customer Care team
to enable the ATS
9.
Follow the manual bypass procedure in Section 3.6 to change the bypass switch from manual to auto bypass.
10.
Using a multimeter, check the grid, battery, and PV voltage on the EI Inverter terminal blocks. All reading should be within spec.
11.
Replace the EI ATS black safety cover, close the ATS door, and torque the Allen screws to 1.8ft-lbs (2.5Nm).
Note:
If the inverter does not turn on after Step 7, then follow this force start procedure.
1.
Open the cover to the right of the EI Battery power switch labeled Force Start.
2.
Press and hold the push button until the “leaf” LED on the battery cabinet is flashing green to force start the inverter.
Once the forced start process completes, the EI Inverter error light will flash red since it will not detect grid voltage.

Issue
Check
In grid-on operation the ATS does not
switch over when there is loss of grid.
1.
Turn OFF the EI Inverter and the grid.
2.
Open the ATS door and check the grid and INV conductors are properly connected to the correct terminals.
3.
The ATS requires an activation. Refer to Section 3.6. Call Tigo Customer Care team:
408-402-0202
Load panel has no power.
1.
Check the Status Display
(1)
for error codes and follow recommended steps if codes are active.
2.
The ATS requires activation. Refer to Section 3.6. Call Tigo Customer Care team.
3.
Verify ATS to EI Inverter communication cable is installed properly.
4.
If issues persist, please contact Tigo Customer Care team.
7. Troubleshooting
3.6 Manual Bypass Jumper Installation
The internal bypass switch is used to electrically bypass the EI ATS during
system maintenance. When switched to the ON position, grid power is
routed directly to the home electrical service panel. However, if
commissioning occurs at a later date, then the bypass feature must be
switched manually so that the home will receive grid power until the day
of final system commissioning.
Follow these steps to manually switch the EI ATS Bypass Switch if the
previous conditions exist:
1.
Turn off the internal EI ATS 200A breaker.
2.
Turn off the EI Inverter DC disconnect switch.
3.
Turn off the 2-pole breaker in ATS that feeds utility power to the EI
Inverter.
4.
Locate the 3-pin connector in the accessories kit and jump pin 1 and
pin 3 using a small wire.
5.
Plug the connector into the EI ATS terminal labeled RSD+ and RSD-.
6.
Remove the EI ATS black safety cover and turn the bypass switch to
the on position.
Note –
To change from manual to auto bypass, unplug the 3 pin
connector, remove the jumper wire, and plug the 3-pin
connector back into the RSD terminal. This ensures the
connector will be available for future maintenance or
troubleshooting.
