FAQs for the Felicity FLA 48460TG2-EU
How long does it take to charge this battery?
That depends on the available charging power of your inverter. With high charging power, the storage unit can be filled very quickly: At up to 12.5 kW (theoretical maximum), in practice this often corresponds to around about 2 hours for a full charge – depending on SOC, temperature and system limitations.
Can I connect two of them in parallel?
Yes. The storage unit is designed for parallel connection. With two units you get approx. 47 kWh capacity. In total, up to 15 units are possible in parallel (up to 352.5 kWh).
How does the battery communicate with the inverter?
Via CAN or RS485. Please check the compatibility and the necessary pin assignment/protocol selection in the documentation of your inverter.
