Questions before quotation

Does 3 kW mean the PV array is also 3 kWp?

No. The current array is six 300W modules, totaling 1.8 kWp. The 3 kW value describes the inverter output class.

What is the listed battery capacity?

The current 25.6V, 100Ah battery provides approximately 2.56 kWh.

How long can the system provide backup?

Runtime must be calculated from simultaneous load, daily energy use, usable battery capacity and available solar charging.
