BATTERY INSTALLATION

Safe and reliable installation requires trained and certified technicians. Therefore, the purpose of this section is only to serve as a guideline as all scenarios cannot be covered.

WARNING :

• DO NOT short-circuit the battery terminals. Doing so can cause bursts in amperage and lead to irreversible damage to the system and the battery.
• Please verify the polarity before connecting wiring. Reversing polarity can and will destroy the
• Please use circuit breakers, fuses, or disconnects appropriately sized by a certified electrician, licensed installers, or regional code authorities to protect all electrical equipment.

Inspection :

Please check for visible damage including cracks, dents, deformation, and other visible abnormalities. The top of the battery and terminal connections should be clean, free of dirt and corrosion, and dry. If any problems are detected with the battery, please contact us for assistance. Refer to the last page of the manual for contact information.

Cable Sizing :

Battery cables (sold separately) should be appropriately sized to handle the expected load. Please refer to the following table for the ampacities of copper cables with different gauge sizes.

The above values are from NEC Table 310.15(B)16 for copper cables rated at 35 C (167 ”I ), operating at an ambient temperature of no more than 30 C (86 T ). Lengths in excess of 6 feet (1829 mm) may require heavier gauge cable to avoid unacceptable voltage drop.

Connecting Batteries in Banks :

WARNING :

• DO NOT string the battery in series. Doing so can cause catastrophic failure.

CAUTION :

• DO NOT string different types of batteries, batteries with different rated capacity, or batteries from different manufacturers in
• Please avoid too high a voltage difference between paralleled batteries, despite the auto-balancing function, to avoid triggering the over-current
• In parallel battery banks, the cables between each battery should be of equal length to ensure that all batteries in the system can work equally together.
• It is not recommended to connect more than 4 batteries in parallel if taking advantages of the auto-balancing function.

To string multiple batteries in parallel, first connect the positive terminals of batteries to each other. Then do the same with the negative terminals. Finally, connect the positive and negative terminals of the first battery to the system. This type of arrangement is used to increase the overall battery capacity while keeping the voltage the same.

Copper Cable

Securing Cable Connections

CAUTION :

• Please secure all cable connections to the proper specification in order to ensure good contact between the cable lugs and the terminals. Over-tightening cable connections can cause terminal breakage and loose cable connections can cause terminal meltdown or fire.
• Please use an insulated Philips screwdriver to tighten the cable connections.
• To ensure good contact between the cable lugs and the terminals, please use the appropriate number of washers to allow for as much thread engagement as possible without bottoming out the terminal bolt. The correct number of washers can be determined by hand-tightening the terminal bolt with just the cable lug in place and observing the gap that is present. Use the number of washers needed so that the washer stack is slightly larger than the observed gap.
• It is very important to ensure the cable lug contacts the top surface of the terminal and that a washer is placed on top of the lug. Do not place a washer between the battery terminal and the cable lug as this can cause high resistance and cause excessive heating of the connection.

NOTE :

• Please use the included Long Terminal Bolts when needed to secure multiple cable lugs on one battery terminal.

Cell Balancing :

The Smart Lithium Iron Phosphate Battery employs bypass resistors to maintain balance between each group of cells within the battery. During the charging process, balancing will start when the highest voltage cells reach a specified threshold voltage and the voltage difference between the highest and lowest voltage cells exceeds the setting value. The bypass resistor will continuously draw energy from the highest voltage cell and dissipate the energy as heat until the voltage difference is less than the setting value. This behavior will slowly bring the entire array into balance and allow the battery to deliver full capacity without any cells experiencing an over-voltage or under- voltage condition.

TROUBLESHOOTING

If any problems occur during battery operation, please refer to the following instructions or contact us for assistance:

• If the Activation Switch is plugged into the UP Communication Port of a battery in active mode, but the LED light on the Power Button does not become bright blue, the battery may have entered protection mode and is in need of special attention.
