5. Configuració i instal·lació

Proper setup is crucial for optimal performance and safety. Always ensure all connections are secure and correct polarity is observed.

5.1 Càrrega inicial

It is recommended to fully charge the battery before its first use. Use a compatible LiFePO4 charger with a charging voltage de 14.6V.

5.2 Connecting to an Inverter

1. Assegureu-vos que l'inversor estigui APAGAT.
2. Connect the positive (+) terminal of the battery to the positive (+) input of the inverter using appropriate gauge cables.
3. Connect the negative (-) terminal of the battery to the negative (-) input of the inverter.
4. Secure all connections tightly using the M8 terminal bolts.
5. Once connections are secure, you may turn on the inverter.

5.3 Series and Parallel Connections (Capacity Expansion)

The DATOUBOSS 12V 300Ah LiFePO4 battery supports both series and parallel connections to expand voltage or capacity. Always ensure all batteries are of the same type, capacity, and state of charge before connecting.

• Connexió paral·lel: Connect positive to positive and negative to negative terminals to increase total capacity (Ah) while maintaining 12V. For example, connecting four 12V 300Ah batteries in parallel creates a 12V 1200Ah system.
• Connexió de sèrie: Connect the positive terminal of one battery to the negative terminal of the next to increase total voltage. Per example, connecting four 12V 300Ah batteries in series creates a 48V 300Ah system.
• Series-Parallel (4S4P): For large-scale systems, you can combine series and parallel connections. For instance, a 4S4P configuration with 12V 300Ah batteries can create a 51.2V 1200Ah system with 61.44kWh usable energy.
