INSTALLATION MANUAL DL-300 DATA LOGGER
IMPORTANT INFORMATION
The DL-300 data logger is the hardware that connects Darfon hybrid inverters to the Darfon cloud monitoring system. Please read all
instructions before installing this data logger. And, store this installation manual where it can be accessed easily.
What You Need Before You Begin
■ Internet service
■ A computer with WiFi
FCC Compliance
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, you are encouraged to try to correct the interference by one or more of the
following measures:
■ Reorient or relocate the receiving antenna.
■ Increase the separation between the equipment and the receiver.
■ Connect the equipment into an outlet on a circuit dierent from that to which the receiver is connected.
■ Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the party responsible for compliance may void the user’s authority to operate the equipment.

MOUNTING THE DATA LOGGER
Location Requirements
■ The DL-300 has an IP20 rated enclosure, which means it must be installed indoors.
■ The RS485 cable is about 4’ long, so the data logger should be mounted no more than 3 feet away from the inverter.
■ The data logger requires an internet connection, be it wired, WiFi or cellular.
■ The data logger can be mounted to the wall, or elsewhere with the use of the din rail and din rail mounts.
Step 1. If the data logger cannot be secured to a stud in the wall, insert drywall anchors prior to installation.
Step 2. Place the data logger against the wall and secure with two screws.

INSTALLATION MANUAL DL-300 DATA LOGGER
CONNECTING TO THE INVERTER
Step 1. Unlock Bypass switch. If there is a screw on the rocker
arm that keeps the Bypass off, remove it with a small
Philips screwdriver.
Step 2. Switch on Bypass, so your load runs from grid while the
inverter is turned off. Make sure the breakers are in the
correct position. Grid and Bypass are on. Load is off.
Step 3. Turn off the main switch that is located on the side of
the inverter.
Step 4. Insert the black wire of the RS485 cable into the first pin,
(T0) D-, and the red wire into the second pin, (T0) D+, of
the data logger. Then use a small flathead screwdriver to
tighten the screws.
Step 5. Open the door on the inverter and remove the dead front cover if needed (See inverter manual for instructions). Look inside and
on the top bulkhead panel you should find a green socket (with 4 pins) labeled “RS485 S”.

INSTALLATION MANUAL DL-300 DATA LOGGER
Step 6. Connect the RS485 connector into the first two pins of
the port labeled “RS485 S” on the inverter. Push the
connector in hard so that it seats properly.
RS485 S RS485 M
Step 7. Insert the USB flash drive into the data logger.
Step 8. Internet Connection. There are three ways to establish an internet connection: LAN, WiFi or Cellular.
LAN Connection
Connect the ethernet cable to the
data logger and to the network/router.
WiFi Connection
Connect the antenna to the data logger.
Cellular Connection
Connect a non password protected
3G/4G dongle to the data logger.
Step 9. Connect the power adapter into the data logger and then to the power outlet.
Note: The power outlet needs to be a backed up so
the data logger will still work when there is no grid.

APPENDIX B: TROUBLESHOOTING
Problem - Not all the inverters are communicating with the data logger/portal.
Step 1. How many Darfon hybrid inverters are connected to the data logger? The data logger can only communicate with up to 3
inverters.
Step 2. Check all communication wires connected to the inverters.
Problem - I registered a new system, but I cannot see the data logger.
Step 1. Make sure the MAC address entered is the LAN MAC address and NOT the WiFi MAC address..
Step 2. Make sure the LAN MAC address was typed in correctly. It must be entered in the following format, xx:xx:xx:xx:xx:xx, with colons
between every two characters. For example, if the LAN MAC is 40D63C031E86, it should be entered as 40:D6:3C:03:1E:86.
Step 3. If the data logger is connected to the router via a LAN connection, make sure the RJ45 cable is properly connected to the data
logger and router. The WAN led indicator should be green.
Step 4. If the data logger is connected to a WiFi network, make sure that it is still properly connected by:
- Connect a computer to the data logger using the RJ45 cable.
- In a web browser, go to “192.168.10.1”. Then log in using the username root and the password SBC700pw.
- In the sidebar menu, click on “Network” and then “Wireless” to go to the Wireless Overview page. Then confirm that your
WiFi network is listed in both the Wireless Overview and Associated Stations sections.
