About Photovoltaic Energy StorageFigure 5 – Phase shift Phase shift is represented as an angle (Ф) and current may be in advance or delayed of voltage. If capacitance of the circuit prevails current is advanced; if inductance prevails current is delayed. This phase shift provokes that "useful power" (active power – unit: W or kW) is lower than the power supplied (apparent power – unit: VA or …
