3. Overview
3.1 Screen
SolisAC-Coupled inverter adopts LCD screen, it displays the status, operating information and
settings of the inverter.
3.2 Keypad
There are four keys on the front panel of the inverter ( from left to right):
ESC, UP, DOWN and ENTER keys. The keypad is used for:
Scrolling through the displayed options (the UP and DOWN keys);
Access and modify the settings (the ESC and ENTER keys).
4. Installation
4.1 Select a Location for the Inverter
To select a location for the inverter, the following criteria should be considered:
Exposure to direct sunlight may cause output power derating. It is recommended to avoid
installing the inverter in direct sunlight.
It is recommended that the inverter is installed in a cooler ambient which doesn't
exceed 104℉/40℃.
3.3 Terminal Connection
Figure 3.1 Keypad
Solis AC-Coupled inverter is different from normal on-grid inverter, please refer to the instructions
below before start connection.
WARNING:
Please refer to the specification of the battery before configuration.

NOTE:
Nothing should be stored on or placed against the inverter.
WARNING:
The inverter must be mounted vertically.
Install on a wall or strong structure capable of bearing the weight of the inverter (15kg).
Install vertically with a maximum incline of +/- 5 degrees, exceeding this may cause output
power derating.
To avoid overheating, always make sure the flow of air around the inverter is not
blocked. A minimum clearance of 300mm should be kept between inverters or objects
and 500mm clearance between the bottom of the inverter and the ground.
4.2 Mounting the Inverter
Dimensions of mounting bracket:
Once a suitable location has be found according to 4.1, please refer to figure 4.3 and figure
4.4 and mount the wall bracket to the wall.
The inverter shall be mounted vertically.
The steps to mount the inverter are listed below:
1. Select the mounting height of the bracket and mark the mounting holes.
For brick walls, the position of the holes should be suitable for the expansion bolts.
Visibility of the LEDs and LCD should be considered.
Adequate ventilation must be provided.

2. Lift up the inverter (be careful to avoid body strain), and align the back bracket on the
inverter with the convex section of the mounting bracket. Hang the inverter on the
mounting bracket and make sure the inverter is secured (see Figure 4.5)
4.3 Assemble the Battery Cables
Step 1. Please unlock the 4*M4 screws on the battery port protection cover as shown in the below
figure.
Step 2. Insert the battery power cables (in package) into the water-proof swivel nut on the cover,
(Break the plastic film on it).
Step 3. Fasten the battery power cables onto the BAT+ and BAT- terminals on the inverter. Please
make sure the labels on cable and inverter match up.
Step 4. Lock the 4*M4 screws and fix the cover onto the inverter.
Step 5. Connect the other side of the battery power cables to the battery.
Please make sure to remove the cover at the bottom of the inverter before assembling the
terminals.
Remove the cover as shown in the picture and follow the direction to lift the cover, make sure
the buckles on the left and right sides are correctly loosened.
WARNING:
To avoid DC Arc, Solis recommends installing DC switch between batteries and
AC-Coupled Inverter.
Ensure the correct polarity of batteries before connecting to the inverter.
WARNING:
Incorrect polarity of the battery cable may lead to permanent damage on
the device.

There are two AC terminals and the assembly steps for both are the same
(AC backup port and AC grid port).
Step 1. Please unlock the 4*M4 screws on the AC ports protection cover as shown in the below
figure.
Step 2. Insert the AC grid cables and AC backup cables into the corresponding water-proof swivel
nut on the cover, (Break the plastic film on it). Make sure you use a cable within the correct
specifications as shown in the table below.
Remove a length of 40mm of the cable jacket and strip the wire insulation to a length of 10-12mm.

Step 3. Fasten the AC cables onto the terminals on the inverter. Please make sure the correct
polarity. Ensure that the correct conductor is fastened (0.7 N.m. torque) to the correct terminal.
Step 4. Lock the 4*M4 screws and fix the cover onto the inverter.
4.5 CT Installation
RAI-3K-48ES-5G inverter requires a CT to measure the power flow to/from the grid.
This will provide information to the RAI-3K-48ES-5G inverter about when to charge or discharge
the battery thus maximizing the self-consumption rate.

NOTE:
To use this function, please contact the manufacturer.
2. Logic interface communication cable (Only for UK)
Logic interface is required by G98 and G99 standard that can be operated by a simple switch or
contactor. When the switch is open circuited the inverter can operated normally. When the
switch is closed, the inverter will reduce it’s output power to zero within 5s.
Pin5 and Pin6 of RJ45 terminal is used for the logic interface connection.
Please follow steps below to assemble DRM RJ45 connector.
Step 1. Insert the network cable into the communication connection terminal of RJ45.
4.6 Assemble Other Cables
1. Battery CAN communication cable
DO CT/Meter
CAN DRM
Step 2. Use the network wire stripper to strip the insulation layer of the communication cable.
According to the standard line sequence of figure 4.16 connect the wire to the plug of RJ45, and
then use a network cable crimping tool to make it tight.
Step 1. Take out the CAN cable (terminal marks ‘CAN' on one end and 'to Battery' on the other end).
Step 2. Unscrew the swivel nut from CAN port.
Step 3. Insert the RJ45 terminal with CAN label into the CAN port, then fasten the swivel nut.
Step 4. Connect the other end to the battery.
Step 3.Connect RJ45 to DRM port (logic interface) .
NOTE:
The CAN cable enables the communication between the inverter and the Li-ion
battery from BYD, PYLON, etc.
Please check for latest model compatibility before installation.

It includes “Stg mode select” which defines different working logic of the hybrid inverter. There
are two options in the Stg Mode Select: Time charging and Off-grid.
Another default mode is Auto mode (Maximize the self-consumption rate) which is
not shown in the setting. Once the inverter is started, it is working in the Auto mode.
If want to switch back to Auto mode, simply turn off the other modes, then it is automatically
operating in the Auto mode, even though it is NOT shown on the screen. The user can set the
time periods, for when the inverter charges and discharges the batteries,
using Time Charging Mode.

6. Commissioning
6.1 Preparation of Commissioning
Ensure all the devices are accessible for operation, maintenance and service.
Check and confirm that the inverter is firmly installed.
Space for ventilation is sufficient for one inverter or multiple inverters.
Nothing is left on the top of the inverter or battery module.
Inverter and accessories are correctly connected.
Cables are routed in safe place or protected against mechanical damage.
Warning signs and labels are suitably affixed and durable.
6.2 Commissioning Procedure
If all the items mentioned above meet the requirements, proceed as follows to start up the
inverter for the first time.
6.2.1 Switch on the AC-backup and AC-grid.
6.2.2 Follow the picture below to select grid standard.
6.2.3 Switch on the DC circuit breaker between inverter and battery.
6.2.4 (Optional) When the battery equipped is Pylon Li-ion Battery,
or BYD battery, turn on the switch on the battery manually.
6.2.5 The relay will make 'clicking' sounds and it will take a short-time
to work automatically.
6.2.7 The system willwork properly.
This function is applicable by maintenance personnel only, wrong
operation will prevent the inverter from working properly.

CAUTION:
Do not touch the surface when the inverter is operating. Some parts may be hot and
cause burns. Turn OFF the inverter (refer to Section 6.2) and let it cool down before
you do any maintenance or cleaning of inverter.
Note:
Never use any solvents, abrasives or corrosive materials to clean the inverter.
Solis AC-Coupled inverter does not require any regular maintenance. However, cleaning the
heatsink will help inverter dissipating heat and increase the lifetime of inverter. The dirt on the
inverter can be cleaned with a soft brush.
The LCD and the LED status indicator lights can be cleaned with cloth if they are too dirty to be
read.
The inverter has been designed in accordance with international grid tied standards for safety,
and electromagnetic compatibility requirements. Before delivering to the customer the inverter
has been subjected to several test to ensure its optimal operation and reliability.
In case of a failure the LCD screen will display an alarm message. In this case the inverter may
stop feeding energy into the grid. The alarm descriptions and their corresponding alarm messages
are listed in Table 7.1:
