Questions before quotation

Why is the product series called 5KW while the inverter lists 5500W?

The existing series name is 5KW System, while the detailed configuration lists 5500W pure sine wave load power.

What are the PV and battery capacities?

Eight 550W modules provide 4.4 kWp, and the 51.2V, 200Ah battery provides approximately 10.24 kWh.

Can this system be selected from the small-business label alone?

No. Equipment starting power, maximum simultaneous load and monthly electricity use must be checked.
