FAQ

A
We recommend users to secure distance within 10 m. For more information, refer to Installation
Manual.
Q Who do I need to contact for any queries? What is the hot line number upon emergency?
A
First search your queries in the FAQ. In addition, you can find answers in the manuals and video
materials under [Customer Center > Download] in the website portal (https://myess.samsungsdi.com).
If no answer, contact us using [Customer Center > Customer Inquiry]. Upon any service-related
emergency, find the emergency contacts in [Customer Center > Service Center].
Q What should I do when I see “Smart meter Connection Error (E603)”?
A
This message appears when a smart meter is not connected in the right manner.
Check if you selected the right smart meter type (D0 type/S0 type) and model from the beginning of
the installation.
For the S0 Types, check if its pulse counts setting is matched with that of our Product.
Q I sometimes see “C128” Error on the web-monitoring screen.
A
Typically, Dynamic IP called DHCP is used for the Internet connection within households, which is
assigned newly every day or every two days by the Internet Company. For this type of IP, “C128”
error may be seen for a period of time to be assigned a new IP. However, it will disappear within 5
minutes when the server connection becomes stabilized
Q Could the installer get an alert/message or email when a failure comes up in one of his end users?
A
The website for installer services was opened in October 2015. You can find answers from the VOC
menu.
Q How much time does it take to fully charge the battery? @ Max charge power.
A It takes about 1.5-2 hours to fully charge the battery with the Max power of 2kW.
Q
Sometimes, it appears that the Product somewhat feeds the grid unintentionally when I check on the
web monitoring screen.
A
It takes about a minute for the product to detect load and reduce its energy production in case the
household load is somewhat reduced (e.g. turning off the heat transfer equipment). In such case,
some partial energy can be fed in to the Grid. Note that our newly developed Product will restrict
such Greed Feed-in. The reason why you see the same screen for five minutes on the web-
monitoring is because our Product’s monitoring cycle is 5 minutes. The actual product traces the load
before the web-monitoring screen is changed and restricts its outputs.
Q The current and voltage values of the Product are not matched to its power value.
A
When the Product is operated at a low power due to its small charging/discharging amount and
energy production, it has a greater volume of reactive power, which leads to inconsistency between
the power value and the current/voltage value.
Q
The numbers are different between the web monitoring and the product LCD (e.g. Grid, PV
generation). Why is that?
A
The ESS products measure the values for Grid and PV generation by itself every specific period of
time. Furthermore, the web monitoring acquires and displays data of the product at an interval of 1
minute. The sampling time difference can result in different values but the differences are not
expected to be great.
Q The battery shape on the LCD screen changes. The up arrow indicates charging or discharging?
A The up arrow indicates discharging.
Q What is the difference between smart mode and basic mode?
