Features
The Lithium Series 24V 2.24 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.
Operation
Battery front
Assembly and 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. Batteries do not require
communication to operate efficiently connected in parallel, either between
them or between battery and inverter. For proper operation of the batteries,
it is sufficient to program the voltage range for the operation with the
following parameters.
- Operating minimum voltage : 23,2V
- Operating maximum voltage: 28,4V
Inverter settings:
- Charge voltage: 28.2V
- Flotation voltage: 27.2V
- Low battery shutdown voltage: 23.5V
- Charge current per unit: 40A
- Equalization disabled.
Warning when doing a battery expansion: It is very important that in the case of connecting batteries in parallel 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 overcurrents 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 six batteries installed and we want to connect two new ones, we must first connect the two new batteries with one of the six 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.

Connection between batteries:
Connect the power cord by plugging the cable into the connectors on the front of the battery. -
Connection between battery and inverter:
25 mm2 power cable section.
NOTE : Each power cord can carry a maximum of 100 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 sufficient to be at the limit
of the maximum current recommended.
NOTE: When battery triggered low SOC, (that means when you find the only
one SOC light is on, or all the SOC light is off), please charge the battery
to till the low SOC alarm disappeared.
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.
- Never connect this battery in series and connect it in parallel only with identical batteries up to a maximum number of 6.
- 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.
