6.1 Controlli pre-installazione

• Ispezionare la batteria per eventuali danni fisici.
• Ensure all connection cables and components are rated for the battery's voltage e corrente.
• Verify that the installation environment is dry, well-ventilated, and within the specified operating temperature range.
• Confirm that your charger is compatible with LiFePO4 batteries and can provide the correct charging voltage (57.6 ± 0.8V).

6.2 Collegamento della batteria

1. La sicurezza prima di tutto: Before making any connections, ensure all power sources are disconnected and wear appropriate PPE.
2. Posizionamento: Place the battery in a stable, secure location.
3. Connessioni terminali: Connect the positive (+) terminal of the battery to the positive (+) terminal of your system (inverter, charge controller, etc.). Connect the negative (-) terminal of the battery to the negative (-) terminal of your system. Use M8 terminal bolts and ensure connections are tight to prevent resistance and overheating.
4. Parallel Connections (for higher capacity): This battery supports parallel connections for increased capacity (up to 4P for 20.48kW total energy). When connecting batteries in parallel, ensure all batteries are at a similar state of charge before connecting. Use appropriately sized cables for parallel connections to ensure even current distribution.
5. Connessioni in serie: NON FARE connect this battery in series. This battery is designed for 48V systems and does not support series connections. Attempting to connect in series may damage the battery and void the warranty.
