We present the simultaneous measurement of the interaction rates R-pp, R-Be, R-pep of pp, Be-7, and pep solar neutrinos performed with a global fit to the Borexino data in an extended energy range (0.19-2.93) MeV with particular attention to details of the analysis methods. This result was obtained by analyzing 1291.51 days of Borexino Phase-II data, collected after an extensive scintillator purification campaign. Using counts per day (cpd)/100 ton as unit, we find R-pp = 134 +/- 10(stat)(-10)(+6)(sys), R-Be = 48.3 +/- 1.1(stat)(-0.7)(+0.4)(sys); and R-pep(HZ) = 2.43 +/- 0.36(stat)(-0.22)(+0.15)(sys) assuming the interaction rate R-CNO of CNO-cycle (Carbon, Nitrogen, Oxigen) solar neutrinos according to the prediction of the high metallicity standard solar model, and R-pep(LZ) = 2.65 +/- 0.36(stat)(-0.24)(+0.15)(sys) according to that of the low metallicity model. An upper limit R-CNO < 8.1 cpd/100 ton (95% C.L.) is obtained by setting in the fit a constraint on the ratio R-pp/R-pep (47.7 +/- 0.8 cpd/100 ton or 47.5 +/- 0.8 cpd/100 ton according to the high or low metallicity hypothesis).
