SOFAR Feed-in limitation box enables the real-time monitoring of grid-tied
situation through the integration of three-phase meter, logger which meets
the requirement of real-time adjusting inverter output power at power
consumption scenario. It can connect to many inverters and support data
transmission via Wi-Fi & Ethernet. It also supports the Feed-in limitation
application of parallel-connected machine for G3 series SOAFR inverters.

ATTENTION
· The SAR-100 should be installed indoors at a safe height, avoiding places
with humidity, dust, direct sunlight and corrosive vapors, and should be
shockproof and pressure resistant; the ambient temperature range
should be around -25°C to +60°C.
· Max. communication distance for RS485 should be less than 500m.
· Away from other wiring routes or pipes in doors, such as gas pipe, water
pipe, electric wire and etc.
· Away from metal structure to ensure wireless signal strength.

Step 1: Connect inverter output to the grid. Connect to phase line R ,S, T, N
accordingly.
Step 2: Connect voltage-sampling signal line, communication distance should
be less than 100m. Connect to phase line R ,S, T, N accordingly.
Step 3: Connect CT, communication distance should be less than10m. CT
direction should be from grid to load and make sure R-phase CT connect
to CT 1-1/2, S-phase CT connect to CT 2-1/2, T-phase CT connect to CT 3-1/2.
ATTENTION
· All electrical installations must be in accordance with local electrical
standards and permission must be obtained from the local electricity
authority before the SAR-100 can be connected to the grid by a
professional.
· When replacing components, ensure that the new replacement
components meet the trial requirements of the SAR-100.
· Ensure that the AC input voltage and current match the rated voltage and
current, otherwise the components will be damaged or will not work
properly.
· Appropriate ESD measures should be taken.
· Please ensure that the following wiring is carried out with the SAR-100
powered off.
· The CT corresponding to M1 is connected to the grid side and S1 and S2 are
connected as shown above with the direction of the arrow pointing from
the grid to the inverter.
· The CT corresponding to M2 is connected to the grid side and S1 and S2 are
connected as shown above with the direction of the arrow pointing from
the grid to the inverter.

6.5 Inverter address settings
Step 1: Default address for meter 1 is 1, default address for meter 2 is 100.
Step 2: ①For one inverter, inverter address: 2.
②For multiple inverters, inverter address: 2, 3, 4, 5……
Step 3: No need to set Feed-in limitation function at LCD screen.
• Address cannot be the same.
• Notice: Please make sure local Feed-in limitation function: OFF
NOTE
Step 4: RS485A-B cannot be reversed.
Step 5: All devices can connect to ground line.
· Phase sequence of CT should be consistent with the phase sequence of
voltage-sampling signal. ±1/2 cannot be reversed.
(Select current sensor according to the device capacity.)

*If the networking configuration is required, please follow the step and the
stick logger along with the inverter does not need to install. If the SAR-100
is only used for Feed-in limitation purpose, users can skip this step directly
and install the stick logger accordingly.

Step 7: If you choose to encrypt AP, you will go to [AP Encryption Modification],
enter your password and click “Save”.
Example: choose WPA2-PSK as encryption mode, AES as encryption algorithm,
password: 1234578 (Please remember the password.)
Users can select encryption mode according to actual situation. After AP has
been encrypted, it requires to connect AP again.
If you forget your password or want to cancel the encryption, please long
press Reset button for 4s to reset which will got to reconfiguration process.
AP password, network information and Feed-in limitation settings will
restore factory settings at this time.
