11 kW Off-Grid Solar System with 8.8 kWp PV and 10.24 kWh Battery

The existing 10KW System entry now presents its actual configuration first: an 11 kW inverter, 8.8 kWp PV array and corrected 10.24 kWh battery. Its main difference from the 16.08 kWh version is battery capacity, not inverter output.

Questions before quotation

What is the corrected battery capacity?

The 51.2V, 200Ah battery provides 10.24 kWh. The previous 14.3 kWh value has been removed.

Why does the H1 use 11 kW while the entry remains 10KW System?

The H1 presents the actual inverter output. The existing series entry and URL remain stable for continuity.

How does this differ from the 11 kW system with a 16.08 kWh battery?

Both use an 11 kW inverter and 8.8 kWp PV array. Their main difference is 10.24 kWh versus 16.08 kWh battery storage.
