What the Felicity records say about this kit
The house profile sized here — 2 × air conditioner, fridge, lights & Wi-Fi, TV, washing machine and kitchen (microwave & kettle) — reaches 8.1 kW in the instant its motors start and takes about 25.4 kWh across a day. On one phase that is a 9 kW inverter. Felicity's single-phase hybrids in this catalogue cover 3–8 kW (T-REX-3KLP1G01 to IVGM8KLP2G1), so no hybrid model is named for this kit. At this size the Felicity listings are the 10 kW single-phase off-grid IVAM10048P1G1 and the 10 kW three-phase hybrid IVGM10KLP3G1.
The array is Felicity's own panel, the GK-1-72HTBD-580M, rated 580 W with 51.47 V open-circuit and 42.59 V at maximum power in its record. 10 of them make 5.6 kWp at 5.7 peak sun hours a day and take roughly 26 m² of roof, where they add about 310 kg (31 kg a panel).
8 hours of this profile without mains come to about 8.5 kWh, and that is what the battery bank is sized against. One LPBA48350TG1 is 17.92 kWh by name, counted here as 16.1 kWh usable.
