Solar system for a farm with evening backup power
A solar system for a farm that keeps water pumps, the fridge and the freezer running through a few hours of evening power cuts. Built around the Felicity Solar T-REX-4KLP1G01 4kW Single-Phase Hybrid Solar Inverter, with Felicity Solar FLS48050SCG1 51.2V 2.56kWh LiFePO4 Battery and 3 × Felicity Solar GK-1-72HTBD-580M 580W Solar Panel.
The same battery (2.3 kWh installed across 1 unit(s)) covers 4 hours and 8 hours alike: 1.1 kWh needed here, 2.2 kWh there, both within it. The array stays at 1.5 kWp. Solar system for a farm with overnight backup power
What is inside
What the Felicity records say about this kit
The farm profile sized here — 2 × water pump, fridge, freezer and lights & Wi-Fi — reaches 3.9 kW in the instant its motors start and takes about 6.7 kWh across a day. Felicity's T-REX-4KLP1G01 is the 4 kW single-phase hybrid unit that covers it. Its record gives a battery window of 40–60 V, 2 MPPT trackers working at 100–500 V, a PV ceiling of 550 V and an IP65 enclosure.
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. 3 of them make 1.5 kWp at 5.7 peak sun hours a day and take roughly 8 m² of roof, where they add about 93 kg (31 kg a panel). The strings are wired so that their voltage stays inside the T-REX-4KLP1G01's 100–500 V MPPT range.
4 hours of this profile without mains come to about 1.1 kWh, and that is what the battery bank is sized against. One FLS48050SCG1 is 2.56 kWh by name, counted here as 2.3 kWh usable. At 51.2 V nominal the bank sits inside the T-REX-4KLP1G01's 40–60 V battery window. The battery's record states a cycle life of more than 6,000 cycles and up to 4 units in parallel. One unit is 31 kg, which decides the vehicle you bring to our store in Dubai or Riyadh.
