About the Manual

2 Introduction
Feed-in limitation box supports the feed-in limitation application of paral-
lel-connected machine for SOFARSOLAR inverter. It enables the real-time
monitoring of grid-tied situation through the integration of three-phase meter,
logger and CT (Customers need to purchase CT by themselves according to
on-site situation), which meets the requirement of real-time adjusting inverter
output power at self-consumption scenario. It can connect to multiple inverters
and support data transmission via WiFi&Ethernet.

5.2 Location
The installation location must meet the following requirements.
• Please install near the crossroad of grid side and grid-tie side. The wiring
length of CT shall not exceed 10m.
• The location recommended is to avoid damp and dust environment. Direct
sunlight and aggressive vapour should also be avoided. The ambient tem-
perature range: -25°C ~ +60°C.
• The maximum communication distance to the inverter should be less than
500m. The communication line should be far away from strong electricity
such as power lines.
• The installation position should be away from metal structures to ensure
WiFi signal quality.

6.1 Check the Packing
Please ensure that the delivery list items are complete (list below):
/05*$&
eIf any item is damaged or missing, please contact SOFARSOLAR.
6.2 Device Installation
Installation Precautions
• It is recommended to install the data logger of the inverter and connect it
to the network.
• Power off the device before installation.
• Please use daisy-chain method when connecting the inverter through
RS485.
• Feed-in limitation box only supports one low-voltage bus and only supports
inverter access under the same low-voltage bus, which does not support
different low-voltage buses (As shown in the picture below).

6.4 Device Wiring
CAUTION
eAll electrical installations must be in accordance with local electrical stan-
dards and permission must be obtained from the local electricity authori-
ty before the SAR-100 can be connected to the grid by a professional.
eWhen replacing components, ensure that the new replacement compo-
nents meet the trial requirements of the SAR-100.
eEnsure that the AC input voltage and current match the rated voltage
and current, otherwise the components will be damaged or will not work
properly.
eAppropriate ESD measures should be taken
ePlease ensure that the following wiring is carried out with the SAR-100
powered off.

6.4.2 Device Hole Diagram
It is recommended to thread according to the diagram, in case of twining and
dislocation which might cause transmitting interference of RS485 communica-
tion and antenna (As shown in the picture below).

6.4.3 Connect to Inverter
The max. number of inverters that SAR-100 can connect to is 10. The A/B of the
inverter RS485 line is connected to the A/B position in SAR-100(As shown in
the picture below).
Baud rate for all inverters: 9600.
A is RS485+ and B is RS485-. If the RS485 link communication is abnormal,
please connect a 120Ω resistor between A and B point of the last inverter.

Inverter address settings:
1. M1 i.e. Meter 1 (Grid side) address: 001, M2 i.e. Meter 2 (Generation side)
address:100, which cannot be changed.
2. Inverter modbus address should be confi gured starting from 002, it is rec-
ommended to use continuous address as 002-011.
3. Please make sure inverter stand-alone feed-in limitation function: OFF.
Disable feed-in limitation at LCD screen according to SOFARSOLAR user
manual.

6.4.4 Connect to CT and AC Line
As shown in the picture above, the CT corresponding to Meter 1 should be
installed on grid side. S1&S2 should be connected as the above picture shows.
The arrow of CT installation should be from grid to inverter.
The CT corresponding to Meter 2 should be installed on generation side. S1&S2
should be connected as the above picture shows. The arrow of CT installation
should be from inverter to grid.
• The length of voltage input connection line should be less than 100m.
And connect to phase line R ,S, T, N accordingly.
• Communication distance between CT and meter should be less than 10m.
• CT of Meter 1 should be selected according to the electricity consumption
