1.1 Data Logger Description
The Solis WiFi Data Logger is an external device which plugs directly into to a port on
the bottom of a Solis inverter. The logger relays information from the inverter to the
Solis monitoring platform, called SolisCloud. This logger connects to a local 2.4GHz
WiFi network, it is incompatible with 5GHz networks. Up to ten Solis inverters can be
daisy-chained together with RS485 to communicate through one WiFi logger. This
logger works with any Solis inverter that has a 4-pin COM port, please reference the
list below for all compatible Solis US inverter models.

1.3 LED Indicator Lights
The Solis S3-WIFI-ST data logger has three LED indicator lights. These lights depict
the status of the logger. There are three lights: NET, COM, and PWR. The chart below
explains what the lights mean when they are flashing, solid, or off. lf the LED lights are
all off when the inverter is getting proper voltages, please contact Solis Support.

Normal Operation:
Once the logger has been configured
properly, all three LED indicator lights should be solid.
Every Five Minutes:
The logger will transmit a data package to SolisCloud.
When this happens, the COM light will flash for a few
seconds. This is normal behavior and should not cause
any concern.

2.1 Pre-Installation Steps
Prior to installing the S3-WIFI-ST logger, the following steps must first be taken to
ensure that the logger will function properly once it has been installed.
1. The Solis inverter is completely installed and commissioned
2. The inverter address is 1: Go to Settings, then to Address, verify the number is 1,
if the number is not one, use the down button to change it to 1 and then press enter
3. Turn the inverter on with both AC and DC power
4. Ensure the WiFi network is 2.4 GHz, the logger does not support 5 GHz
5. Verify that WiFi network password is correct - check it by connecting with your phone
6. Check the signal strength of the WiFi network you plan to connect the logger to by
performing a network speed test.
See section 2.3 for instructions on how to connect multiple inverters to one logger

2.2 Installation Steps
Figure 2.1
COM Port
The data logger plugs into the 4-pin COM port on the bottom of the inverter wire box.
This port is protected by a black cap that screws on. The first step is to unscrew the cap.
Figure 2.1 shows the Solis-1P10K-4G-US inverter wire box as an example.
Other Solis inverters will have a similar green COM port on the bottom of the wire box.
Step 1: Locate the COM port and remove the protective cap
The minimum WiFi signal strength for the
logger is -90 dBm (20% RSSI) which equates
to approximately 11 Mbps upload speed.
Distance from the router to the logger should
be no more than 300 feet with no obstructions.
If there are obstructions, this distance is
significantly less. Please install a WiFi range
extender if the upload speed is under 11 Mbps.

Step 2: Attach the antenna and plug the logger into the COM port
A.Screw the antenna onto the logger. Then plug the logger into the COM port. Be sure
the LED indicator lights are facing forward. The logger will only plug in if the joint matches.
B.Twist the black lock ring at the top the logger clockwise until it feels snug against the
bottom of the inverter. Be careful not to rotate the silver casing during this step.
match the joint
2.3 Connecting Multiple Inverters to One Data Logger
First, the inverters must first be daisy-chained together with RS485. The logger can
support a maximum of ten inverters. If there are more than ten inverters on the same
system, then additional loggers must be installed. Please see the inverter manual for
instructions on how to complete the daisy chaining.
Step 1: Daisy chain the inverters together with RS485 communication cable.
Step 2: Plug the data logger into the first inverter in the daisy chain.
Step 3: Adjust the address for each inverter.
Note: The first inverter should be set to 01. Each of the other inverters in the chain must
be set to a number other than 1.To do this,follow the steps:
A. Go to the Settings menu of each inverter and then to the Address submenu.
B. Use the up/down buttons to change the address number
C. Press enter to save the new address of the inverter
For example:
Inverter 2 = address of 2, Inverter 3 = address of 3... Inverter 10 = address of 10
Step 4: Commission the logger like normal. Each inverter in the daisy chain will populate
into SolisCloud once the logger transmits the first data packet.
The logger will collect and transmit information from all of the inverters in the daisy chain
to SolisCloud. Only the logger gets added to the new plant on SolisCloud. The inverters
will automatically populate into the plant once the logger starts to report to SolisCloud.

Step 1: Connect your phone to the data logger’s access point network
3. Configuration
Open your phone WiFi settings and look for the WiFi network that starts with “Solis_”
followed by the data logger serial number. Tap that network to connect to it. Enter the
password and then tap Join. This is the logger access point (AP) network.123456789
If you get a message stating that the password is incorrect or if the logger WiFi network
does not appear in the list of nearby networks, press and hold the Reset button on the
back of the data logger for 15 seconds.
If the AP network still does not appear or if the password fails again, contact Solis Support.
Configuration and Commissioning Overview
Connect phone to logger
access point network
Go to logger configuration
page on a browser app
Select the desired WiFi
network & enter password
Wait ten seconds for the
logger to communicate
Download SolisCloud and then
register a new account
Create a new plant for
the system on SolisCloud
On the new plant, go to
add a device
Scan the sticker
on the logger
Wait five to ten minutes
for the logger to report
Once the logger reports, the inverter(s)
will auto-populate into the new plant The system has now been commissioned
