Tools
The following tools are required to install the battery pack:

• Wire cutter
• Crimping Modular Plier
• Screw Driver

NOTE

• Use properly insulated tools to prevent accidental electric shock or short circuits.
• If insulated tools are not available, cover the entire exposed metal surfaces of the available tools, except their tips, with electrical tape.

Safety Gear
It is recommended to wear the following safety gear when dealing with the battery pack:

• Insulated gloves
• Safety goggles
• Safety shoes

Installation

Inventory of items
Thoroughly inspect the packaging upon receipt of goods. If there is any item missing or if there is any damage to the external packaging or to the unit itself upon unpacking, please contact us immediately.

Installation Location
Make sure that the installation location meets the following conditions:

• The installation site must be suitable for the size and weight of the battery.
• Must be installed on a firm surface to sustain the weight of battery.
• The area is water proof.
• There are no flammable or explosive materials in proximity
• The ambient temperature is within the range from 0°C to 45°C.
• The temperature and humidity is maintained at a constant level.
• There is minimal dust and dirt in the area.

CAUTION
If the ambient temperature is outside the operating range, the battery pack stops operating to protect itself. The optimal temperature range for the battery pack to operate is 0°C to 45°C. Frequent exposure to harsh temperatures may deteriorate the performance and life of the battery pack.

Minimum clearances
Observe the minimum clearances to walls, other batteries or objects as shown in the diagram and picture below in order to guarantee sufficient heat dissipation

Installing the Battery Pack

Mounting to a wall

WARNING
In order to avoid electrical shock or other injury, inspect existing electronic or plumbing installations before drilling holes.
The battery is heavy, please handle with care to avoid damage to the product or injury to the installer.

1. Choose suitable firm wall with thickness greater than 200mm.
2. Use the mounting frame as a template, mark the hole position.
3. Drill 4 holes according to the hole position, it is ø10 with depth 100mm.
4. Hammer the M8 screws to the above holes, and screw the nut. Note: Do not position screws flush to the wall – leave 10 to 20 mm exposed.
5. Fix the mounting frame to the 4 screws.
6. Raise the battery a little higher than the mounting frame whilst maintaining the balance of the battery. Hang the battery on the frame through the match hooks.

WARNING
Falling equipment can cause serious or even fatal injury: never mount the inverter on the bracket unless you are sure that the mounting frame is firmly mounted on the wall after thorough checking.

Parallel use of battery

Parallel use of battery ( All off-grid solar inverters )
Rosen power wall battery is a smart battery to match all off-grid solar inverter ( 48VDC) types. When the battery needs to be used in parallel, the maximum connection is 14 units, but we recommend 2-4 units according to application. The lithium battery have matched for Growatt SPF series off-grid solar inverter .
When connecting with other off-grid 48VDC solar inverters, it does not need to add CAN/RS485 communication cables with inverters, if inverter brand factory does not have CAN/RS485 port, just plug and play use.
