problem about battery parameters in simscape

Hi I have a power pv panel power P=135 w; Vmpp = 38 V and = Impp=3.5 A I need the output voltage V=220 v, so we should put 6 panels in series 6 *38 = 220v My problem is how I can parameter the battery following my power. I want to use ''battery'' in simscap matlab library. Thank you in advance
