This paper presents a study about an autonomous (off-grid) photovoltaic (PV) system making use of the novel Lithium Iron Phosphate (LiFePO4) as a battery pack for isolated rural houses. More particularly, this paper study and test the behaviour and efficiency of a low-cost isolated PV system for typical rural houses near Luena in Angola. The propos...

... The solar regulator is a device that is positioned between the solar modules and the batteries, also known as a charge controller. It is the guarantor of the energy level stored in the batteries [12]. ...
... The battery capacity must be able to cover all the electrical needs (E c ). When we size the batteries' capacity, we apply the following dimensioning rule [12,14]: ...
... Off-grid inverter produces a voltage wave, with an independent frequency from the grid. Not only does the inverter convert DC to AC power, but it may also regulate the PV system if correctly dimensioned according to the battery voltage levels [12,14]. Table 5 summarizes the recommended international standards for inverters intended for photovoltaic applications. ...
