Battery Dimensions

Features

The Lithium Series Dual 48V 5.1 kWh battery has the following features:

Designed for use in photovoltaic applications.
Battery Management System (BMS): The BMS system built into the battery that monitors its operation and does not allow it to work outside the bounds of the design regime (V, I).
Expandability: The system’s accumulation capacity can be expanded by incorporating more batteries.
Can be connected in series and parallel connection.
Wi-Fi module: The battery has a built-in Wi-Fi module, so you can see the battery information and operate it remotely..

ASSEMBLY AND CONNECTION

PARALLEL CONNECTION

Batteries may be connected in parallel up to a maximum of 8. All batteries must be grounded. It is suggested to connect the installation ground to the rack at the same point as all battery lands.

Connection between batteries:

Up to 8 batteries are allowed to be used in parallel.
The batteries used in parallel must be the same batch of cases with the same SOC.
The Voltage difference of batteries used in parallel must be within 1V.
The dimensions of parallel cable must be the same.

Connection between batteries

Connection between battery and inverter:

Connection between battery and inverter

2AWG power cable (35 mm2)

NOTE: Each power cord can carry a maximum of 200 A, so every two batteries would need to connect a new cable to the inverter. However, if the inverter is 5 kW only with one cable it would be enough to be at the limit of the maximum current recommended.

Warning when doing a battery expansion: It is very important that in the case of connecting batteries that are not new (for example, we add a new battery to an existing system), we previously perform a voltage balancing (without load) between them to avoid over currents that could damage the system. As an alternative to balancing voltages, balancing can be done by equalizing the SOC of the batteries. In addition, when connecting new batteries, we must take into account that the number of batteries at the time of connection must be similar to the number of batteries that are already connected in the system. For example, if we have five batteries installed and we want to connect a new one, we must first connect the new battery with two of the five that were already in place to balance them, and then connect these three with the other three remaining batteries in the system. Batteries should always be connected in groups of similar numbers so that a large group cannot damage a smaller group of batteries at the time of connection.

SERIE CONNECTION

Batteries may be connected in serie up to a maximum of 8. All batteries must be grounded. It is suggested to connect the installation ground to the rack at the same point as all battery lands.

Connection between batteries:

Up to 8 batteries are allowed to be used in series.
The batteries used in series must be the same batch of cases with the same SOC.
The Voltage difference of batteries used in parallel must be within 0.1V.
The dimensions of parallel cable must be the same.

Connection between batteries

For the series connection of the batteries, we need yo modify the battery cables first. These are designed so that the negative connector only fits the negative terminal, the same with the positive one. For the modification, we need to disassemble the head of the cable we want to interchange of pole, to later assemble the one we need to install.
We well require a M5 HEX wrench, a flat head screwdriver (optional), and both cables

series connection

The process will be described in the followen steps:

Unlock the head
• We need to ensure that the head of the cable is in the unlock position.
Withdraw the head of the connector
• We need to slightly move up both locking flange in order to unlock the head piece.
Unscrew
• We will use the M5 HEX wrench to withdraw the screw which ensures the head position of the cable.
Withdraw head
• We need to withdraw completely the head of the cable. Once done that, we will interchange it by the analogue cable
Final assemble
• We proceed to assemble the heads of cables once we have interchanged the head of the cables, following the previous steps inversely

CONFIGURATION WITHOUT COMMUNICATIONS

For those cases where the battery is intended to operate connected to an inverter without communications, it’s not necessary to select a specific configuration of the DIP switches and the batteries do not need to be connected each other with the communication cable.

DIP CONFIGURATION

Each module has 5 DIP switches (SW1, SW2, SW3, SW4 and SW5) that will be configured differently according to the system requirements, the battery connection and the inverter.

Dip Configuration

SW1 is for communication protocol with inverter. If CAN protocol is used, 1 and 2 must be ON. If 485 protocol is used, 3 and 4 must be ON.

SW4 and SW5 work to communicate with the inverter and depend on the communication cable and the inverter protocol.

If using a pin-to-pin cable, the DIP configuration is as follows:

SW2 and SW3 are for communication between batteries. It depends on whether it is series or parallel connection, or if is master or slave. The switch configuration must be as follows:

| Please make sure the SW2 DIP switch is selected correctly. if the battery is connected in parallel mode, but DIP8 is at ON position, it may occur a serious and dangerous fault. Instead, if battery is connected in series mode, but SW2 DIP8 is at OFF position, it may occur a serious and dangerous fault.

On and Off

To turn on, press the power button for few seconds. The BMS will start and the LED will light up.

To turn off the batteries, press the power button for more than 5 seconds.

Faults and troubleshooting

Each error is presented with a description. If the Fault light is on, check the error in the APP. If the battery cannot be seen on the app, please check the battery status first. If the battery status is OFF, turn on the battery and then check that you are connected to the Internet.

Appendix

SECURITY INSTRUCTIONS

Please read the battery instructions before use.
Keep the battery away from high voltage and out of reach of children.
In operation, the battery should be kept in the set temperature ranges (between -10ºC and 50ºC) and a humidity less than 80%.
During handling, be very careful to avoid bumps/falls of the battery.
Be careful not to touch the contacts at the same time.
The battery, at the end of its useful life, requires a recovery process, not disassemble it.
Avoid locating batteries in damp places to avoid danger.
When not in use for a long time, store the battery intact and let the battery be half charged. Wrap the battery with non-conductive material to avoid direct contact of the metal. Store the battery in a cool, dry place.
Never expose the battery to fire or water.

SAFETY WARNINGS

Do not disassemble the batteries. The inside of the battery has a protective mechanism and a protective circuit to avoid danger. Improper disassembly will damage the protection function permanently, leaving the battery without safety conditions.
Never short-circuit the poles of the Battery. Avoid contact of positive and negative poles with metals.
Keep the batteries away from fire and extreme temperatures. Monitor the distance to thermal bulbs, stoves, etc.
Keep the battery away from the water. Always be careful that the battery is not located in damp places where the dew point can be reached.
Do not use batteries that have physical damage that may be due to falls or bumps.
Do not weld near the battery.
Overheating will result in the loss of the protective function of its life cycle, even, it could render the battery useless and in extreme cases self-ignition of the battery occurs.
Connect this battery only with identical batteries up to a maximum number of 8 in series or parallel.
If the battery has liquid leakage, avoid contact with it completely. It can be harmful to the skin, and if you touch the eyes, wash, and go to the hospital immediately for treatment.
