Do not subject it to any strong force. To help prevent damage, leave the battery in its shipping packaging until it is ready to be installed.
• [Warning]: Do not insert foreign objects into any part of the Wattsonic Li-LV Battery.
• [Warning]: Do not expose the Wattsonic Li-LV Battery or its components to direct flame.
• [Warning]: Do not install the Wattsonic Li-LV Battery near heating equipment.
• [Warning]: Do not immerse the Wattsonic Li-LV Battery or its components in water or other fluids.
• [Caution]: Do not use cleaning solvents to clean the Wattsonic Li-LV Battery, or expose it to flammable or harsh chemicals or vapors.
• [Caution]: Do not use fluids, parts, or accessories other than those specified in this manual, including non-genuine Wattsonic parts or accessories, or parts/accessories not purchased directly from Wattsonic or a Wattsonic-certified party.
• [Caution]: Do not place the Wattsonic Li-LV Battery in a storage condition for more than one (1) month, or permit the electrical feed to be severed for more than one (1) month, without placing it into a storage condition according to Wattsonic's specifications.
• [Caution]: Do not paint any part of the battery, including internal or external components or the exterior shell or casing.
• [Caution]: Do not connect the Wattsonic Li-LV Battery directly to photovoltaic (PV) solar wiring.
• [Caution]: When installing the Wattsonic Li-LV Battery in a garage or near vehicles, keep it out of the driving path. If possible, install it on a side wall and/or above the height of vehicle bumpers.

Environmental Conditions

• [Warning]: Install the Wattsonic Li-LV Battery at a height that prevents damage from flooding.
• [Warning]: Operating or storing the Wattsonic Li-LV Battery in temperatures outside its specified range might cause damage.
• [Warning]: Do not expose the Wattsonic Li-LV Battery to ambient temperatures above 60°C (140°F) or below -30°C (-22°F).

Standard Packing List

• Li-LV LFP Battery Module
• Battery Backsheet (mounting bracket)
• Battery<-->Inverter Cables (power cables for connection between battery and inverter)
• Battery<->Inverter RJ45 Communication Cable (cable for data communication)
• M6 Expansion Screws (fasteners for mounting)
• COM Resistor (component for signal strength)

Installation Instructions

Mechanical Installation

Single battery installation

Step 1: Confirm the exact mounting position of the battery backsheet. Ensure a minimum of 200mm clearance above ground. Use M6 expansion screws to fix the battery backsheet on the wall according to the fixed position.

Step 2: Hang the battery module onto the mounted battery backsheet.

Multiple battery installation

Step 1: Confirm the exact mounting position of the battery backsheet. Ensure backsheet spacing is greater than 20mm. Use M6 expansion screws to fix the battery backsheet on the wall according to the fixed position.

Step 2: Hang the battery module onto the mounted battery backsheet.

Electric Connection

Top connection interface

The interface includes:

1. Battery<-->Inverter Power Cables (+)
2. Battery<-->Inverter Power Cables (-)
3. Communication cables (up)
4. Communication cables (down)
5. Battery Reset Button
6. DC Isolator
7. Grounding Point

Cables Connection and COM Resistor

Step 3: Connect battery power cables and communication cables as shown in the diagrams. Plug the COM resistor into the last communication interface, which is open. The COM resistor is mandatory for strengthening the CAN Bus signal, regardless of whether it's a single battery or multiple batteries in parallel.

Wattsonic standard parallel kits

Maximum withstand current is 100A. For larger load demands, a DC Combiner box can be configured.

Start the Battery Array

Step 4: Pull on the DC Isolator to the ON position.

Indicator Light Status

• Green: Normal operation, 30% < SOC < 100%
• Flashing Green: Normal operation, 10% < SOC < 30%
• Red: Alarm or Protection
• None: Power Off or Sleep

System Setting

NORMAL OPERATION

During normal operation, if Li-LV LFP Battery Modules are installed correctly, the inverter and battery will start communication immediately and begin processing power commands. Refer to the inverter manual for further configuration instructions.

• [Warning]: Do not operate Li-LV LFP Battery Module unless all covers are in place.
• [Warning]: Do not disconnect anything from or add anything to Li-LV LFP Battery Module.
• [Caution]: Do not try to communicate with Li-LV LFP Battery Module using third-party tools or diagnostics for the Li-LV LFP Battery Module and the inverter.
• [Caution]: Do not lean on, stack anything on top of, or hang anything from Li-LV LFP Battery Module or the conduit.

LI-LV LFP BATTERY MODULE CARE

Keep the top edge of the Li-LV LFP Battery Module clear of articles to maintain optimal airflow. To clean the Li-LV LFP Battery Module, use a soft, lint-free cloth. The cloth can be dampened with only water if needed; it should not be dripping.

• [Caution]: Do not use cleaning solvents to clean Li-LV LFP Battery Module.
