This is so because increasing the voltage of a system causes a reduction in the current through it and in turn reduces the size of the wires you need. This saves you losing voltage over a long cable from panels to converter. The 160 watts solar panel is a 24 volt. You need 4 six volt batteries or two 12 volt batteries.

Voltages above 24 are 24 volt panels. Using a 24 volt supply instead of a 12 volt supply greatly reduces the wiring cost to almost half the original cost. 12 volt panels usually contain 36 individual solar cells each cell at 0 5v comes at around 18 volt for the panel. Or 8 watts to 16 watts.

Alternatively you can tell this by physically seeing the panels.
