2.5 How it works

- 6 -
Morning
Afternoon
Optimized self consumption will be
achieved. ESS are used to store the
excess energy produced by PV system.
Extra energy will be fed into the grid
when ESS are fully charged and system
has already meet its load requirement.
Evening
Night
ESS will power the AC load when the
sun sets.
If the ESS capacity is insufficient to meet
self consumption requirement, electricity
will be obtained from the grid.
2.6 Features
The RAYSTECH Residential ESS has following features:
Energy storage unit: This battery is suit for PV solar system compatibility.
Battery management system (BMS): The battery built-in BMS monitor. It
prevents the battery from running outside of the design, limitations. See
Troubleshooting on Chapter 8.
Monitor: The battery BMS built-in with WIFI module, the battery running
information could be seen in mobile phone and computer.

- 7 -
Easy firmware update: The BMS firmware can be updated to the latest version.
See Chapter 9 Firmware Update.
Expandability: The battery capacity can be increased by adding other batteries.
See part 5.4 cable connections.
3 Guidance for disconnection of batteries during shipment
1) Cartons that have been crushed, punctured, or torn in such a way that contents
are revealed shall be set aside in an isolated area and inspected by a skilled
person. If the package is deemed to be not shippable, the contents shall be
promptly collected, segregated, and either the consignor or consignee
contacted.
2) The DC circuit of RAYSTECH Residential ESS has been disconnected before
outgoing.
3) A precautionary label had been affixed to the shipping carton to alert
individuals as to the battery within the package have been disconnected;
otherwise, the battery should not be transported.
4) We have conducted comprehensive tests to ensure the equipment they
distribute around the world is safe for shipping transport. These products shall
be handled with care and immediately inspected if visibly damaged. lf the
cartoon visibly damaged,please contract with RAYSTECH customer careline to
confirm whether the battery could be used safely or not.
4 Installation Prerequisites
4.1 Installation location
Make sure that the installation location meets the following conditions:
The building is designed to withstand earthquakes.
Far away from the sea to avoid salt water and humidity.
The floor is flat and level.
No flammable or explosive materials nearby.
Optimal ambient temperature is between 15℃ and 30°C.

- 8 -
Temperature and humidity stays at a constant level.
Minimal dust and dirt in the area.
No corrosive gases present, including ammonia and acid vapor.
The RAYSTECH Residential ESS is rated at IP20, so the battery could be installed
indoor.
If the ambient temperature is outside the operating range, battery will protect itself
by shutting down. The battery optimal operate temperature is 15°C to 30°C.
Frequent exposure to severe operating condition would exacerbate the
performance and lifetime of the battery.
4.2 Installation process
The battery should be installed according to the following flow chart.
4.3 Installation materials
Following installation materials should be prepared by installers.
Power cable

- 9 -
Data cable
Ground wire
Bipolar external isolator, when two or more battery systems in parallel, each of
them shall have a bipolar isolator.
NOTICE
Make sure that the cross-sectional area of charging cables is 25 to 35
mm2.
A breaker between RAYSTECH battery and inverter was recommended
to install, and the breaker’s min. current should be over 150A or
following with local regulations.
4.4 Tools
To install the battery pack, those following tools are probably required:
Phillips screwdriver
Torque wrench
Cable crimper
Wire clamp
Voltmeter
Tape measure
Drill
Flat-head screwdriver
In order to protect operator and installer’s safety, please select and use suitable
tools and measuring instruments that are certified for precision and accuracy.
4.5 Safety instruments
When dealing with the battery, following safety gears should be equipped. Installers
must meet the relevant requirements of IEC 60364 or the domestic legislation and
other relevant international standards.
Insulated glove
Safety goggles
Safety shoes

- 10 -
4.6 Network cable
If needed, the network cable should be made like this diagram. But the network
cable between battery and Inverter should be made following the definition of
Inverter. If available, use a LAN cable tester to check whether the cable is faulty.
4.7 Storage
If the battery is not to be installed immediately, or removed from operation and
needs to be stored for a long period, please choose an appropriate location to
store it. Instructions for storage are:
Do not stack more than 8 battery boxes.
The temperature of battery stored recommended in the range of -20°C to 25°
C.
Do not expose to water
The ESS box should be upright and not stacked upside down when storing the ESS
box.
If the ESS needs to be stored over 3 months, the DC circuit of battery suggests to
be disconnected. Otherwise, the battery would discharge at a minimum rate and
capacity degrades depended on storage time, the battery self-consumption is less
than 5w. And, if the battery stored over 6 months, it is suggested to connect the
battery with inverter and commission the system.

User Manual
5.2 Checks before installation
There are a few things to check before installing the battery to ensure that it has no
defects.
Check item 1: Check the battery voltage.
WARNING
If this checking process is executed for any reason
after the battery is fully installed, make sure that the
inverter is turned off or break the connection
between battery and inverter while checking the
battery.
Press and hold the panel button for about 4s and then
release it after the two LED lights on, measure the voltage at
the terminal interface with a voltmeter. If the voltage is lower
than 48 V, do not use the battery and contact RAYSTECH
customer careline or your distributor.
5.3 Installation the battery
NOTICE
The symbol located on the front of battery, For Parallel connection, the
earth wire was recommended to be installed.
5.3.1 Connect with 51.2Vdc Inverter
To prevent the battery from moving, make sure the battery fixed to a wall.
NOTICE

that the wall or platform is capable of supporting the battery’s weight.
5.3.1.1 Wall mounting

- 12 -
1. Determine bracket mounting place
to be fixed using this Positioning
cardboard.
2. Drill holes in the wall for the M8
expansion screw anchors, which
depth should be at least 50 mm.
Tighten the screws to a torque
around 2.5 N∙m.
3. Fasten the battery to bracket, fasten
the holes with M6 screws with
2.0N∙m roughly.
4. Meanwhile, two or four batteries
could be installed by theses brackets.
Note: if more than 4 batteries installed, a cabinet recommended to be selected for
the battery’s stable.
5.3.1.2 Ground installation
Meanwhile, RT-5100S battery also could be installed on floor, the installation step
as following:
1. Fix the bracket to battery’s mounting
holes one by one.

- 13 -
2. If more power and energy needed, 2
to 4 batteries could be installed in
one stack.
3. If the number of batteries at the
range of 5 to 8, a cabinet is
recommended to be selected.
5.3.2 Address selection of Master and Slave battery(ies) connection
