Solar system for an office with overnight backup power
A solar system sized for an office that carries lights, Wi-Fi and computers through a full night's power cut. Built around the Felicity Solar FLA48500 51.2V 25kWh LiFePO4 Battery, with 16 × Felicity Solar GK-1-72HTBD-580M 580W Solar Panel — order the rest online from the Felicity Solar catalogue.
If 4 hours are enough instead of 8, the storage needed falls to 6.7 kWh — 12.9 kWh installed across 1 battery unit(s), 9.6 kWh less. The array stays at 8.9 kWp. Solar system for an office with evening backup power

What the Felicity records say about this kit
The office profile sized here — 3 × air conditioner, 2 × lights & Wi-Fi, 4 × computers and kitchen (microwave & kettle) — reaches 9.2 kW in the instant its motors start and takes about 40.4 kWh across a day. On one phase that is a 10 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. 16 of them make 8.9 kWp at 5.7 peak sun hours a day and take roughly 42 m² of roof, where they add about 496 kg (31 kg a panel).
8 hours of this profile without mains come to about 13.5 kWh, and that is what the battery bank is sized against. One FLA48500 is 25 kWh by name, counted here as 22.5 kWh usable. The battery's record states a cycle life of more than 6,000 cycles and up to 15 units in parallel. One unit is 218 kg, which decides the vehicle you bring to our store in Dubai or Riyadh.
