FAQ

A
You can set it up in the same way as you set up PV installation capacity, Feed In capacity, and energy
meter on the installation registration screen (SIM).
Q Do I need the DC/AC Breakers?
A
Yes, you need the DC disconnection switch on the PV side and the AC breaker on the AC. For more
information, refer to 5.7 Distribution Box Locking Method in Installation Manual.
Q
It appears to be the “Wrong number” when I (Installer) try to register my given Serial number at the
Web portal.
A
Pop-up message appears when registering a serial number at the Web portal, saying “Check if you
input the serial number correctly.” This message is just to inform users to recheck their input serial
number. However, a lot of users think that this message means “The number you just input is a
wrong number”. We have received many calls related to this user’s misunderstanding.
Q Where is the installation/Web registration manual? Can’t Samsung SDI provide one?
A
For more information, in the website portal (https://myess.samsungsdi.com), access [Customer Center
> Download] and refer to Installation Manual.
Q How the Web-portal data will be processed if the network connection is lost?
A
When the network connection is lost, there are no data remaining at the Web-portal.
However, data related to error occurrence and the other normal data are stored, in the SD card
embedded inside the Product, per each error occurrence and every 10 seconds, respectively.
Samsung SDI’s headquarter can check applicable data, if necessary.
Q Is it okay to connect only one PV module to the strings?
A
Yes, it is. There will be no problem in the Product’s operation by doing so.
To know more about PV connection, refer to section 5.9 in Installation Manual.
Q How can I join the Web monitoring portal?
A
Type “https://myess.samsungsdi.com” and connect the website. (Please note the https procedure.) If
required, select “Go to Customers” or “Go to Installer” for login. For more information, in the website
portal (https://myess.samsungsdi.com), access [Customer Center > Download] and refer to Installation
Manual.
Q How can I create the Installer Account?
A
Request for creation of your account to SDI’s Sales Person in your region or by email to the following
email address: [e-mail].
For more information, refer to Installation Manual.
Q
I have connected my ESS to the Internet. Still, I see the sate called “Standalone” at the engineer
page.
A
It is because the Product was not connected to the server well.
Check if the Internet cable is connected well to the LAN port on the side.
Reboot the router and check if the Internet connection of that router is okay.
Q What digital meter probe shall be used?
A
We recommend users to use a KMK 111 optical probe.
For more information, refer to Installation Manual.
Q
Please provide Samsung SDI’s recommended methodology for “initial setting” when using the EM24
DIN Digital Meter. (Installers of Garlo gavazzi and memodo are mostly using this.)
A
Select “1000 pulse/kWh” and proceed installation.
For more information, refer to Input of Installation Information, Installation Manual.
Q Up to which distance from the Product is the Digital meter capable of operating?
