Questions before quotation

What does 16 mean in this system configuration?

It describes battery energy capacity, calculated at approximately 16.08 kWh. It does not mean 16 kW inverter output.

What are the inverter and PV capacities?

The current inverter output is 11 kW and the PV array is sixteen 550W modules, totaling 8.8 kWp.

Why is the historical 15kw-system URL retained?

The historical 15kw-system URL remains to protect existing links, while visible names and specifications now show the technically accurate configuration.
