- If you enroll in a new account, respond to the email message sent to verify your email address
2. Tap + to configure a new system
3. Enter the system name and turn on date and tap Next
4. Confirm your location and tap Create to save the system information
Select Equipment - Scan for Inverter
1. Tap Select Equipment
2. Tap Scan
3. Tap Add
Configure Inverter
The following symbols will guide you through commissioning:
- Section complete - Section incomplete - Section requires correction
1. Tap Internet Settings
2. If using Wi-Fi, drag the screen down to refresh the list of networks and connect to desired network
For a wired connection, select Ethernet and apply the appropriate settings
3. Perform updates as needed
4. Tap Inverter Settings, select the Grid Code, configure Advanced Options, and tap Save
Add PV Modules
1. Tap PV Modules
2. Edit inverter model and MPPTs if needed, then tap Add String
3. Select a Manufacturer, Model, and PV Modules count and tap Save
If the PV Module is not on the list, press the + sign at the top right corner to add a new item
4. Repeat until all strings are added and tap Done
For assistance commissioning Tigo TS4s, ensure you have the Paper Map as described here: Commissioning a TS4 System - Getting Started – Tigo Help Center
Then, skip to the Configure Layout section of this article: Create and Edit a TS4 System - Using EI App (Mobile) – Tigo Help Center.
View Inverter Real-Time Production, Warning, and Fault Data
1. Return to the EI Setup screen and tap the three-dot icon on the top-right corner of the screen
2. Tap Real-Time Data
Batteries
1. Tap Batteries & Meters
2. Tap Scan Barcode for Warranty and capture the battery barcodes
Changing EI Battery Modes
1. Tap the Settings icon (bottom right).
2. Tap Energy/Battery Management.
3. Select the desired battery mode. This setting can be changed by the homeowner.
ATS
1. On the EI Setup page, tap Inverter Settings
2. Tap Advanced Options
3. Tap ATS
4. Scan and Save the barcode
5. Update the ATS if needed.
6. Perform a backup test to ensure backup functionality. Below are the steps:
- Ensure system is fully commissioned
- Verify the inverter is synced to the grid and producing (Sun LED will be SOLID GREEN)
- Turn off grid power and confirm the backup loads are still on
Commission the Generator
1. Tap the Settings icon (bottom right).
2. Tap Generator Management
3. Select the inverter that controls the generator and tap Connect
4. Select a generator mode and tap Save
-
Auto (default) – The generator starts if the battery state-of-charge (SOC) falls below 20% and stops when the SOC reaches 95%
-
On – The generator runs continuously to power loads and charge the battery. This mode can help if loads exceed the power available from the solar array and battery
- Pause – The generator does not run until the Auto or On mode is set
Test Generator Functionality
Prior to following the steps below: Turn off the grid power to the Tigo ATS
- The ATS will shift to backup mode
- The Tigo Inverter and Battery will also switch to backup mode
- The house will now be running on solar and battery power
STEP 1 Test Generator Manual Start
Attention! If you manually start the generator then you must manually stop it.
Although the generator will stop charging the batteries at 95%, the generator will continue to run until it is manually shut off. |
STEP 2 Test Manual Stop
|
STEP 3 Test Generator Auto Start
Attention! You must leave the generator running in ON mode until the battery reaches a 95% state of charge to test the auto stop feature.
If you manually start the generator then you must manually stop it. |
Verify Generator Energy Flow While Generator is Running
Attention! When the generator is running, it is the only source powering the loads. However, both the generator and the PV can charge the batteries at the same time. Notice how the energy flow shows no flow from the Inverter to the Home. This is because the Generator powers the loads, and the rest of the generator power charges the battery. This is normal behavior. |
STEP 4 Test Generator Auto Stop
|
If the system experiences abnormal behavior during these tests, manually stop the generator and perform necessary troubleshooting.
Troubleshooting
Issue | Solution |
The generator will not auto start |
|
The generator will not charge the batteries |
