Description of the required specifications of the various components (Charge Regulator and PV Inverter).

Regulator Specifications:

The input voltage ------ Rated = 24 V ----- Should sustain 2*(Voc-each PV panel)

                                                                                                   = 2*21.6 = 43.2

                            So, choose  Vin 50 V

The output voltage ----- (2*10.8 [21.6]– 2*14.4[28.8]) >>>> (20V-30V)

                            So, choose Vout (20V-30V)   

The input power > Ppv,

                            So, choose Prat = 1000 W.

Inverter Specifications:

                              Choose Vin (20V – 30V)

                              Choose Vout (210V– 230 V) ac 1-ph , 50 Hz

                              Choose Prat > Pconnected
