Rigoberto Depending on the autonomy and power you need, you should know that there is a wide variety of deep cycle batteries. In the link you have a 2V @ 2490AH. With what you can do a bank of 12; 24; 36; 48; 72; 96; 120; 220V You have to think that the bank's tension and capacity will need an appropriate charger for it. In addition, the inverter must be for the same supply voltage of the bank. The supply voltage of the inverters is normalized, you cannot use any voltage, otherwise you will not find chargers or inverters. You can find 300KW inverters, which are ready to use. http://webosolar.com/store/es/baterias-ciclo-porfundo/986-bateria-surrette-rolls-2-ks-33p-ciclo-profundo-2v-2490ah.htmlrigoberto
