General Guidelines and Requirements

• The battery may be installed in an outdoor or indoor location.
• Since the battery must be secured to a wall using the supplied mounting bracket, the installation location must be adjacent to a wall.
• When installed indoors, the battery must not be obstructed by any building structure, room furniture or equipment.
• The battery shall not be exposed to direct sun or rain.
• Since the battery has natural convection, the installation site must be clean, dry and well ventilated.
• The installation location must allow easy access to the battery for installation and maintenance.
• The front panel should not be covered.

Restricted Locations
Do not install the battery at any of following locations:

• residential rooms
• wall or ceiling niches
• entrance/exit areas or below a staircase/passage
• environments with humidity and condensed water level of over 90%
• earthquake zones where additional safety measures are required
• sites at altitudes of more than 2000 meters above the sea level
• sites exposed to direct sunlight or sites where the ambient temperature may exceed the specified maximum temperatures
• near flammable materials or gases or explosive environments

Clearance
Observe the following minimum clearance 20 cm from all sides of the battery module

• 30 cm from another battery module or any heat source, such as water heater unit, gas-fueled heater, air conditioning unit or any other equipment
• 100 cm from emergency exits
• 30 cm from doors
• 20 cm from windows or air vents
• 20 cm from other devices

Residential Barrier
In order to prevent a fire from spreading, install a non-combustible barrier on the other side of the wall or structural surface, on which the battery is installed. If the installation surface is not made of a non-combustible material, a non-combustible barrier can be installed between the battery and the wall or structural surface. If the Battery pack is installed on a wall or at a distance of 300mm from the wall that isolates the energy storage system from a residential space, the distance from other structures or objects must be increased.

Installation procedure

1. Install a floor stand (recommended by SolarEdge):

2. a. Place the floor stand at a distance of 3-5cm from the wall.
   NOTE
   The arrow should point at the battery module front.

3. b. To level the floor stand, adjust each of the four legs by turning the screw using a flat screwdriver.

4. c. When the floor stand is balanced, tighten the nut with an open wrench in order to secure the leg’s height, then close the nut. CAUTION!
   Before moving the battery module to its location, make sure that both the CB switch and the soft switch of the battery module are off.

5. Take the battery module out of the box, move it to the installation location. You can use the battery handles located at the top of the battery for convenience of moving and placing it on the the right position.

6. Place the battery module on the floor stand using the top handles.

7. Put the bracket on the wall, mark the drilling holes location, then remove the bracket and drill holes in the wall.
   NOTE
   Don’t drill through the bracket.

8. Assemble the supplied mounting bracket to the battery module using two M5 screws. Tighten the screws to a torque of 2.5Nm.
   NOTE
   For better cable routing, use the mounting bracket oval hole in a way to enable the maximum available distance between the battery module and the wall.

9. Secure the battery module to the wall with screws and wall plugs. When using only two screws, make sure to use the two outer screws as shown on the figure below.

10. When installing battery modules in a tower configuration (one on top of the other):

11. Before securing the wall brackets, make sure the battery modules are aligned (see the figure below).

12. Secure all battery modules to the wall as described above.

13. Note that the maximum allowed amount of battery modules in a tower is three.

Connecting a Single Battery Module
If you are installing a single battery module, connect it to the inverter as follows:

1. Make sure the battery module’s DC switch is off.
2. Before connecting the cables to the inverter, make sure the accessory kit is on the correct length. If you need longer cable, you will have to crimp the connectors yourself using one of the following kits:

IAC-RBAT-5KCNCT-01

| 10 DC connector (red) 10 DC connector (black) 10 RJ45 connector

10 waterproof RJ45 connector

---|---

IAC-RBAT-5KCNCT-02

| 20 DC connector (red) 20 DC connector (black)

20 waterproof RJ45 conn

3. Release the three screws and slide the side door, that covers control interfaces on the left side of the battery module, to allow clear and secure access to the battery module interfaces
4. Before continuing with the installation, please make sure the battery is OFF, then make sure that the front panel LEDs are OFF. If the battery is on, use the following procedure to turn it off:
5. a. To turn off the battery module circuit breaker, remove the cover screw, click the door open, turn off the circuit breaker.
6. b. Press the power button for 3-6 seconds until the indicator lights go out.
7. Connect the CAN-bus communication cable (RJ45) coming from the inverter, with the top battery module connector
8. Use the left grounding terminal to connect the battery module, depending on the local regulation, to the inverter grounding or to the main grounding
9. Use the upper pair of DC connectors (BAT- and BAT+) to connect power from the inverter. Note the polarity. Insert the connectors until you hear a click.

9. Turn on the battery modules, refer to Powering on the Battery Module on page 27. Press the soft switch shown on the figure below for 3-6 seconds, the LEDs will light. If this is a new battery (e.g. not RMA) only the first green LED or the first and second green LED should light constantly. No other LEDs should light. If you observe a different LEDs sequence, refer to LED Indications on page 1for LED troubleshooting, or contact SolarEdge support with the Battery module SN and the LED sequence. Until this is solved, do not proceed with the installation CAUTION!
Before turning on the battery module circuit breaker, make sure that the cables to the inverter are connected, with the DC cables, to the inverter at the right polarity. Failing to do so, may cause either the battery or the inverter to malfunction.

10. Turn on the circuit breaker.
11. Close the side door and route all the cables above the door.
12. Fasten the side door with the three screws

Connecting Multiple Battery Modules

CAUTION!
Before connecting additional modules, make sure the CB and the LEDs are OFF When installing multiple battery modules, connect them in parallel. Contact SolarEdge or your distributor to order the appropriate cable kit for your configuration. For cable kits and accessories, see What’s in the Package on page 9.

1. Open the side doors of the battery modules.

2. We recommend to turn off the soft switch in all battery modules.

3. Connect the DC, communication and grounding cables between the battery modules, as shown below (example; your actual configuration may differ).

4. Connect the DC and communication cable of the first or last battery module to the inverter. See the inverter installation guide for connection instructions.
   NOTE
   When you have two battery modules on top of each other, they are connected in a way that the top connectors of the lower battery module are connected to the bottom connectors of the upper battery module.

5. Fasten the side door with the three screws.

Powering on the Battery Module

1. Turn on the DC switch.
2. Press the power button for 3-6 seconds until the indicator lights are on.

Top Cover Installation
After installing the battery and making all the connections, install the top cover on the top battery module in every tower.

1. Take the top cover out of its box
2. Remove the top plate screws
3. Place the frame on top of the top battery module in the tower, secure it with the 3 screws provided in the kit
4. Assemble the top plate with the 5 screws
